Cryogenic Batch Freezers for Pharmaceutical Applications 

Our CES Pharmaceutical Systems division continues to deliver high quality, flexible solutions to the Life Science industry and has been strongly engaged with the rapid
development of vaccine manufacturing.

This year 2021 we can announce that again a Cryogenic Pharmaceutical Batch Freezer has been delivered to our customer GSK in Belgium.

The Pharmaceutical Batch Freezers are delivered according the User Requirements Specifications (URS).

Please contact us for more information.

CES delivered last month multiple new Cryogenic Batch Freezers to customers in Germany, Denmark, Italy, France and Malaysia

The CES batch freezer offers the benefit of full cryogenic freezing or rapid crust freezing and chilling for handling and packaging of delicate or soft products.
The CES batch freezer is an efficient freezing method that uses indirect spray for rapid freezing. Cold vapor is recirculated by means of recirculation fans.
Nozzles are adjustable to cope with changing freezing requirements or items requiring slower freeze times to prevent surface fractures.
Freezer controls are arranged in a user friendly, easy to operate control panel HMI Siemens.
Cryogenic spray and batch cycle time are easily adjustable for any variety of food items.
All CES Batch Freezers are equipped with the most up-to-date safety control systems.

In total CES has produced about 800 Cryogenic Batch Freezers that have been deliverd world-wide.

Cryogenic Tunnel Freezer

CES was asked to produce a Cryogenic Tunnel Freezer for a specific application linked to a packaging problem.
The product needed to be ‘crust’frozen all around except the bottom of the product. In this way actual problems with the full automatic packaging machine could be solved.

For this application CES installed a Cryogenic tunnel Freezer with a blue polyethylene conveyor belt. At a setpoint of -50°C the product will have a ‘crust’ frozen on top
and on the sides. The bottom of the product is not frozen as the Polyethylene conveyor belt is acting as an insulator.

So job well done and happy customer in Italy !

CES – Cryogenic Long-tunnel for freezing of fish in different sizes.

CES had delivered a cryogenic (LIN) long tunnel for freezing of fish in different sizes to a long established German company. It was the target to replace an older tunnel,
that couldn´t be rented anymore by our client, by an excellent scalable, flexible cryogenic machine.
This was perfect possible for CES.

The freezer – in one of the CES-standard-belt widths of 1220 mm –has been designed, on wish of our client to freeze large and heavy fish in one piece.
That was the reason to design the strong standard-CES-heavy duty belt system and gearbox in reinforced version for very heavy loads.
The infeed and outfeed heights of the old tunnel needed to be exactly the same for the new machine. That was the reason to design the tunnel in an slight angle.
The freezer has been equipped with the proven HOTL-hydraulic lifting system.

CES had delivered, together with the machine, exhaust ventilators CT250 and insulated exhaust systems too, all in stainless-steel.
The machine is controlled and monitored by a Siemens-PLC with touch-panel.
The CES-CTC-Software allows, despite an easy and neatly arranged operation, a very detailled adjustment of the unit and process-parameter.
All relevant states of the LT are indicated on the touch-screen in one view.

Despite the very tight time frame for manufacturing, delivery and installation could this project be handed over to our client exact in time.
The planned production could start without delay.

Bosch India CTC Chamber

CES received the first enquiry for a possible installation of a new Sub-Zero Treatment Chamber from Bosch Nashik (India) in February 2018.
CES was able to manufacture exactly what Bosch Nashik India demanded and this after many very interesting conference calls with Bosch India (and Germany)
to determine the exact specifications or User Requirments Specifications.
A FAT protocol and SAT protocol was also established between CES and Bosch.

This CES Sub-Zero Treatment Chamber was installed in February 2020 in India and I’m happy to confirm that the SAT (Site Acceptance Test) has been approved by
both companies.

CES was, is and will remain the leading manufacturer for Sub-Zero Treatment + Quenching Chambers worldwide with a temperature range
between -160°C to +350°C according AMS2750 and CQI9.

Tumbler Freezer Meatless (The Netherlands)

The veggie market is in full expansion and operation. Our long-term existing customer in The Netherlands who is providing the food industry unique texturized
plant-based ingredients for over 15 years is in full development and needed therefore a bigger capacity freezer.

First CES provided a testunit to be 100% sure that the newly build Cryogenic Tumbler Freezer would do the job.
 The test results were very positive. 100% IQF freezing was established.

CES installed a newly build Cryogenic Tumbler Freezer with an integrated Immersion Nitrogen bath at infeed to crust the product before fedded into the Tumbler.

Another happy existing customer who can count on the enormuous experience of the CES staff.


Mechanical Spiral Freezer 

CES was asked to replace an old spiral freezer on exact the same footprint ! Infeed and outfeed of the products needed to be imperatively on the exact same location.
As if this was not already easy the client also asked a 30% raise in production capacity.
CES managed to do all this within a timeframe of 3 weeks at site of the client.
The installed CES spiral is equipped with :
• CO2 DX evaporators with sequential defrosting system – Spiral is running 24h/24h
• Full CIP (Cleaning In Place) system
• Belt width of 915mm adapted to receive 2 production lines of Brussels Waffles

Frozen Food Challenge … Bring it On !

Special Requirements are No Problem for CES !

CES delivered two new box freezers to a well-known producer of fish products in Germany. The new CES machines replace two very old machines from another company.

The existing machines were equipped with long ramps in front of the doors, while the new CES-freezers are designed without outer ramps. No problem !

The new freezers feature :
• Fully welded interiors and exteriors
• Stainless steel hinges and locks, standard
• A standard CES PLC System for easy operation and handling during production.

The machines are somewhat custom made ; they are a bit longer for our customer’s long trolleys.
Also, the interior freezing room features a protective skirting on both sides and on the back wall. Additionally,
CES has modified the bottom-integrated ramp to meet the customer’s requirement that none of his sensitive products fall from the trolleys during loading and unloading.

The customer also wanted to avoid using any painted parts, so CES equipped the freezers with stainless-steel fan motors instead of standard fan motors. To round out the project, CES has also delivered stainless-steel made exhaust tubing for the two box freezers.

CES Meets Special Demands with Expertise and Responsiveness

CES delivered a new box freezer to an electroplating workshop in Germany. Our customer removes coating from his electroplating frames.

The CES freezer features standard, fully welded construction inside and out, as well as stainless steel locks and hinges.
The machine is controlled by a CES-standard-Siemens-PLC for easy operation and handling during production.

Basically, it is a standard CES box freezer, but one which needed slight reconfiguration to meet client demands.
First, he required extended inner height for optimal positioning of frames inside the machine.
Second, he required a special reinforced roof area to support a transport system that easily loads and unloads the frames.

CES met these requirements with no difficulties.

Clearly visible is the special extended height of the machine


CES salutes a three-time customer ! Aubert & Duval, a specialist in heat treating Aeronatutic components, has invested to increase their reactor shaft production capacity.
Having been satisfied with CES heat treatment boxes on separate occasions in 2010 and 2015, Aubert & Duval once again turned to us for a third machine.
Not only were the latest developments incorporated into this most recent order, they were also retrofiitted into the two existing machines in order to extend their production cycles.
In fact, CTC are able to treat shafts during a 6-8 week operation without stopping.
CES has integrated high-performance cryogenic valves, an injection system to keep an overpressure in the machine during the opening for the change of workpieces.

The aeronautical qualification AMS 2750-E was carried out in September for a commissioning validation.

CES Replaces Linear Tunnel with Three Box Freezers

ESCAL is a major player in frozen seafood that made its name with escargot. An existing linear tunnel freezer at their Strasbourg facility could no ensure
optimal freezing in the face of increased demand. In addition, the trip through the freezing tunnel required extensive product handling and placement in perforated plastic boxes.

Both of these conditions created potential quality hazards for a sensitive product such as snail.

The customer therefore opted for the integration of three new freezing boxes in place of the tunnel.
A test was performed upstream with a dual flow CES test box to validate the process.

CES engineering means quality escargot – bon apetit !

Another Successful VEGGIEFOOD freezing project in Belgium

CES develops, engineers, and manufactures our in-line cryogenic 3-belt tunnel freezers to process all kinds of foods, ranging from small products to bigger parts.

The unique hydraulic CES Top Lifting System is a proven technology in use for more than 30 years.
We designed the system according the highest hygienic standards to provide the customer a very easy cleaning and maintenance experience.

Our end-customer has chosen Liquid Nitrogen as their cryogenic gas for two important reasons; first, LN is highly flexible, with an operating temperature
from ambient to -150°C. Second, LN delivers perfect high-end quality of their cryogenically frozen products compared to mechanical freezing of the same product.

So, eat your vegetables – they’re delicious, thanks to CES!


CES had a full year to prepare for this project, which consisted of dismantling an existing multi-belt linear freezer and mounting a new mechanical
spiral freezer in a very limited space. But after that year of preparation, we would have only three weeks to execute !

After confirming the dimensions of the machine for its integration into a very limited space, we built this freezer in the CES factory.
In this way we could avoid any disappointment during the August installation – when the plant was down for summer holidays.

                                                                                                        MOUNTING IN CES FACTORY


CES techs dismantled the roof and part of the walls to facilitate and expedite handling due to the tight schedule.
The cold production managed by SOS FROID was also partially implemented before the plant shutdown.

This freezer can process 750 kg per hour of nems (Vietnamese egg rolls) just out of the fryer, with a delta of 105 ° C.
It is equipped with a sequential system that allows it to work continuously, with a horizontal flow, a stainless steel belt and a stainless finish on all the insulating panels.

The electric cabinet is equipped with the latest Siemens hardware. This manages both the production recipes and the machine parameters with ease.
An Ethernet communication to the cold production API manages the exchanger’s inversions as well as the various informations for this direct expansion CO2 project.

BONCOLAC and CES : The Sweet Life !

French processor BONCOLAC is a major player in frozen desserts and frozen appetizers.
When the company expanded its Rivesaltes factory, BONCOLAC chose CES to supply two cryogenic freezing boxes.
These liquid nitrogen freezers preserve the organoleptic and structural qualities of the products during defrosting.

CES built the boxes for mirror integration. The cell crate and all technical elements are in the technical room. Only the electrical cabinets are accessed from the production room.

Dessert, anyone ?

CES Delivers BIG Results in a SMALL Footprint

CES recently delivered two new box freezers to a leading German egg product processor.
The new machines join four long-standing CES S-type box freezers on the production floor.
Rising demand meant production increases would take the four existing units to capacity.

The CES box freezers are fully welded inside and out, with stainless steel hinges and locks, as well as insulated bottoms and stainless steel fan wheels.

In addition, CES provided an upgraded Programmable Logic Controller (PLC) and updated interfaces to deliver seamless control, easy operation,
and superior handling to units new and old.

Of course, increased production rarely allows for increased production SPACE ! The site had floor space and height limitations,
so the customer requested a unit that could deliver results in a smaller footprint. We heard him, and provided him a small,
but indeed heavy duty batch freezer based on our CES-standards. He was able to increase production smoothly and effectively !

If your output is growing faster than your floor space, CES can help. So, put our engineering expertise and responsive service to the test . Contact us today !

Cryogenic Shrink Fitting

Freezing equipment for high-end electric vehicle assembly ready to ship. CES can provide equipment for cryogenic treatment and shrink fitting.

Cryo-treating with subsequent tempering can improve material properties resulting in stress relief, plus increased toughness and wear resistance. Shrink Fitting, or
“compression fitting,” is a process that inserts a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. The shrink fitting process can be
used as an alternative to conventional press fitting, or more likely, to permit a mechanical fit that otherwise could not be accomplished via the mechanical force of press fitting.

The Standard of Clean

The acronym SS is often associated with stainless steel, but when referring to the latest CES design-build the SS means, Sanitary and Safe. The challenge that was given to us
by the customer was based on stringent standards set by AMI (American Meat Institute) and the ever-growing OSHA safety requirements. The result is a CO2 tunnel that is
cleanable at a microbiological level and safe enough to meet any production floor specifications.

To ensure AMI sanitary standards were met, strict attention and detail were paid to the product zone of the tunnel. All surfaces are finished to 16 Ra and all welds are
continuous,smooth and polished to ensure that there are no niches in the zone. To eliminate pooling and allow for self-draining, there are no horizontal surfaces in the
product zone. The UHMW belt supports and FDA approved silicone gasket material used in the COP design are compatible with the product, environment, and cleaning
chemicals. Finally, standoffs and our signature top lifting design allow for easy access to locations where disassembly is not possible.

The electrical cabinet and controls were designed and tied together by CES and certified by UL 508A. Using all Allen Bradley components, six variable frequency drives were
used to control the stainless steel fans in three separate cooling zones. This allows the operation of the top fans at different speeds than the side fans in each zone, maximizing
air flow while ultimately preserving product position. A CO2 monitor, proximity switches, and interlocks were integrated to meet OSHA Class 2 Safety requirements.

The new challenge has become finding a tunnel that’s cleaner and safer!

CES strength is present in aeronautics

CES was retained by a French aeronautic group to supply a chamber for cryogenic heat treatment. This equipment was integrated into the various phases of heat treatment to
increase the mechanical resistance of components as part of the reactors of civil planes, such as driving shafts. Parts are loaded from a deck by automatic conveyors through
a hydraulic operated guillotine style door. The chamber is capable of holding up to 4 tons of parts per batch and may reach temperatures of -150F for several hours in order to
meet the stringent aeronautical standard, AMS 2750-E
CES Freezing equipment has the eternal life

Please take a look at both pictures. It pertains to CES equipment that is 25 and 18 years old.

Both the 18-meter long tunnel and the spiral freezer were recently overhauled in our factory and have been installed at other customers to start a second life.

Both look like new and goes to show that CES Freezing equipment is engineered and built to the highest quality standards leading to an extended life and lowers the cost of

The way CES Freezing equipment is designed and built enables the customer to move it around inside and outside their facility.

Next time you are considering buying new freezing equipment keep CES and their design capabilities in mind. Also if you have CES freezing equipment that needs
overhauled contact us.

The expertise and reactivity of CES

From design to installation in only 6 weeks, this liquid CO2 tunnel freezer is utilized to crust freeze the outside surface of meat products. The crusting allows more accurate
slicing during further processing.

One of the unique features of this particular tunnel freezer is the dual belt design. The two parallel belts can be driven at different speeds allowing the user to simultaneously run
multiple products with different residence times. This gives the customer twice the flexibility of one tunnel.

As always, standard to all CES freezers are the hydraulic operated top-lifting design, PLC, and color touchscreen. The top-lifting design allows for increased access to the
inside of the freezer for maximum sanitation, while the PLC and color touch screen provides advanced control capabilities and ease of use.

CES installs two cryogenic Box-Freezers for Cooling of sausages before slicing

CES has installed two large cryogenic Box-Freezers for cooling sausages before the slicing process. The two freezers are specially equipped with over-sized doors,
each machine has two doors. The freezers have been installed between cold storage and the slicing room at the customer's facility. This was done to give them the
capability to freeze the product easily while shifting the trolley to the freezer in the cold room, processing the meat and after the process putting it in the slicing room.

Additionally the bottom of the freezers had to be designed as a heavy duty version to be capable to handle the weight of the equipment and the product trolley that
weights up to 2500kg. Another request of the customer was to open the doors only after cleaning with the CO2-gas completely, and with no air from outside the building
should be used to avoid contamination of the product. Instead of dry, clean air from the production room should be used. CES has designed a special system with an
automatic stainless-steel blower-fan, installed on top of each freezer. CES also delivered all additional necessary insulated piping for exhaust and CO2 to bring the gas
outside the building without any dripping of water and to ensure a high-quality CO2-supply for the freezers.
Slicing the cost of freezing Kebab

CES completed the installation of a new nitrogen spiral line for freezing sliced Kebab meat. This new system will be replacing the customers’ existing immersion freezer making
the process much more efficient and increasing the overall capacity at the same time. Reducing liquid nitrogen consumption by up to 65% and increasing output allows our
customer to improve their bottom line. CES spiral freezers provide much more accurate temperature control and product uniformity compared to immersion style freezers and
minimize maintenance costs at the same time. Designing this solution to fit the customers’ existing production floor layout reduced installation downtime and kept expenses at
a minimum.

No matter how you slice or skewer it this Kebab line was a win-win for our customer.

Mechanical Cooling of Cookie Butter Spread Jars

CES successfully installed a new Mechanical Cooling tunnel to chill this delicious Belgian alternative to peanut butter. A custom designed solution replaces the company’s
existing rack and cart cooling system and virtually eliminates all previous manual product handling and labor. Expertise and know-how enabled our engineers to design
a variable speed vertical airflow system which greatly improves cooling efficiency, temperature uniformity, and product throughput. This fully automated system provides reliable
and continuous cooling for up to 18,000 jars per day.

Worlds largest cryogenic tunnel
CES’ North American facility recently completed the world’s largest cryogenic tunnel freezer for one of the most delicious products. This is an exceptional project that was
completed this summer at our customer’s new top-of-the-line production site.

At almost 100 feet in length with a usable belt width of 5 feet, it is three times larger than the most common size tunnel freezer. We are expecting to see more of these giant
sized freezers in the future due to the continued growth of the frozen food market share. The consumer demand for convenience foods and specifically frozen meals is ever
growing. Increasing the freezer size while maintaining the quality of the freezing process does not always have an obvious solution. The challenge lies in uniformly
distributing the cryogen and properly recirculating the cold gases throughout the system. CES’ decades-long freezing experience allow us to overcome these challenges
and engineer efficient and reliable solutions to meet our customer’s goals.


For this new production line of delicious products, our customer decided that the advantages of cryogenic freezing outweighed those of the typical mechanical refrigeration
system setup. Cryogenic freezing provided a high level of flexibility for product changeovers and increased freezing speeds. The initial capital investment and integrations
cost was significantly lower compared to conventional freezing methods while providing a better quality frozen product and flexible processing parameters. Another major
factor was the quick turnaround time that CES can offer to manufacture cryogenic equipment as well as the very short installation and implementation time. Due to our
extensive experience and in-house engineering and manufacturing capabilities, we can quickly build a fit-to-suit freezing solution for any size production line. This allowed
us to complete this major freezing project in only twelve weeks from start to finish.

 CES ingenuity Increases Plant Efficiency and Production Capacity

One of the largest bake-off bakeries turned to CES to engineer, manufacture and install a new Double Drum Proofing spiral and a mechanical spiral freezer. The client
specializes in sweet and savory puff pastry take-&-bake products ranging from croissants to chocolate bread.

Due to the sticky nature of some of these products the conventional low-tension spiral drive systems was not a good solution. CES partnered with Intralox to integrate
the DirectDrive system for both of these massive spiral applications. The Intralox DirectDrive system is an ideal solution for challenging applications where sugar or
coatings interfere with the typical drum overdrive found in low-tension spiral drive applications.

The Double Drum Proofing spiral houses 2,300 meters (7,500 ft) of conveyor belting and is capable of running at speeds of up to 27 meter (89 ft) per minute with a usable
belt width of 1 meter (40 inches). Temperature uniformity is maintained between +28°C and +32°C (+82°F - 89°F) with a variable humidity of 72% to 85%. CES’ experience
and the implementation of state-of-the-art technology allow this new proofing solution to operate 24 hours a day, 7 days a week.

CES designed and manufactured many spiral freezers but none as large as the one installed for this project at this client's facility. Providing 1,150 meters (3,800 ft) of belt length
and 640kw (182 tons) of refrigeration capacity makes this one of the largest mechanical freezing systems ever created. Using a sequential defrost system allows the
customer to produce 24/7 without the need for a shutdown. The Intralox DirectDrive system provides for smooth and reliable operation of all 41 tiers of conveyor housed
in this massive masterpiece.

Our customer was very pleased with the timely completion and installation of the project as well as the low-cost maintenance the integration of new spiral technologies
provided. CES is a licensed Intralox DirectDrive system integrator and is therefore among a select few companies that can provide their customers with this exciting new

Total Cryogenic Project

CES executed a 'Total Cryogenic Project' at a large poultry processing company in Belgium including:

Two Cryogenic Tunnels and curve belt, more than 50 meters vacuum LIN Piping designed to the customer's specifications. Four frequency-controlled exhaust systems
(2 exhausts on each machine) with more than 20 meters of insulated exhaust

CES installed two Cryogenic Tunnels with a total freezing length of 27m [88.5ft] on a belt width of 1.22m [48in].

The Tunnels are equipped with a hydraulic opening top section, ideal for cleaning and perfect hygienic conditions.

Both machines are equipped with specially designed in- and outfeed belts. The height difference between infeed belt and tunnel b
elt is only 20mm [0.78in].

They are equipped with LIN-injection systems on both in- and outfeed sections (the client is able to have a go- or counterflow of the LIN gas) This results in less LIN
consumption for cooling and freezing of product. The two machines are controlled by one central PLC unit.

The client can program 100 different recipes according to their wide range of product.

Complete Freezing/Glazing line for shrimp

CES designed, manufactured and installed a complete Freezing/Glazing line for a shrimp producer in Europe.

CES installed a complete freezing/glazing line with a capacity of approximately 2.2 tons/hour at the leading shrimp producer in Europe. The line consists of one immersion
freezer and three freezing tunnels, two with a length of 10 meters and one with a length of 9 meters. Furthermore, four vibrating glazing units were delivered. The width of
the complete line was 1.22 meters.

The individual quick freezing (I.Q.F.) of raw, peeled small and medium-size shrimp is a real challenge, as known by seafood processors worldwide. An innovative freezing
method recently developed by CES has proven to be very successful. Raw, peeled shrimps are very sticky and slimy, and the often vibratory feeders are unable to
separate the sticky shrimp before they entering the freezer, making the I.Q.F. freezing impossible.

CES clearly understands this problem and can offer you its innovative freezing method bringing a solution for the problem you have been trying to solve for such a long time.

CES has also a vast experience with developing equipment to freeze other delicate fish products such as tuna, salmon, surimi, coated fish products, etc....
