2 Pallet Vacuum Cooler – CC-VC-200
The Cold Change 2 Pallet Vacuum Cooler is a compact industrial vacuum cooling system designed for the rapid pre-cooling of fresh produce, vegetables, flowers and other temperature-sensitive products.
Also commonly referred to as a vacuum chiller, vacuum pre-cooler or vacuum cooling machine, the CC-VC-200 uses vacuum technology to rapidly remove field heat and product heat following harvest or production.
With capacity for 2 pallets per cooling cycle and loads of up to 800kg per pallet, this industrial vacuum chiller is ideally suited to growers, packhouses and food processors that require fast cooling without the capacity or footprint of a larger multi-pallet machine.
Vacuum cooling can dramatically reduce the time required to bring suitable products towards their required storage or transportation temperature, helping protect product quality and maintain an effective cold chain.

What Can Be Vacuum Cooled?
Cold Change vacuum cooling systems can be configured for a wide variety of fresh produce and food applications, including:
- Mushrooms
- Lettuce
- Broccoli
- Cauliflower
- Leafy vegetables
- Spinach
- Herbs
- Celery
- Sweetcorn
- Fresh vegetables
- Flowers and cut flowers
- Turf
- Selected bakery products
Different products have different cooling characteristics. Cold Change can therefore configure the vacuum chilling cyclearound the product, pallet weight, loading arrangement, starting temperature and required final temperature.
How Does Vacuum Cooling Work?
Unlike conventional air cooling, vacuum cooling does not rely solely on cold air gradually removing heat from the outside of the product.
Products are loaded into a sealed vacuum chamber and the pressure inside the chamber is reduced.
As the pressure falls, the boiling point of water also falls. A small quantity of moisture within or on suitable products begins to evaporate at a low temperature.
This evaporation absorbs heat from the product, allowing heat to be removed rapidly throughout suitable produce.
This is why a vacuum cooler or vacuum chiller can achieve extremely fast and uniform pre-cooling for certain fresh produce compared with conventional cooling methods.
Vacuum Cooling Mushrooms
Vacuum cooling is particularly suited to many mushroom applications because freshly harvested mushrooms can require rapid removal of product heat before storage, packing and transportation.
A 2 pallet mushroom vacuum cooler can be an excellent option for smaller and medium-sized mushroom growers, specialist producers or facilities requiring a dedicated lower-capacity vacuum chilling machine.
Rapid pre-cooling can help mushrooms reach their required cold-chain temperature much sooner after harvesting.
Read our complete Vacuum Cooling Mushrooms Guide for more information about mushroom cooling cycles, cooling times and the potential benefits of vacuum cooling.
Lettuce & Leafy Vegetable Cooling
Vacuum cooling is widely used for lettuce and other leafy vegetables because suitable leafy produce can be cooled rapidly throughout the load.
For growers handling lettuce, spinach and other leafy crops, rapid post-harvest pre-cooling can significantly reduce the time between harvesting and reaching the required cold-chain temperature.
A 2 pallet vacuum cooling machine can therefore provide a compact solution for farms and packhouses that need rapid lettuce or leafy vegetable cooling.
Read our Vacuum Cooling Lettuce Guide and Vacuum Cooling Leafy Greens Guide for more information.
Broccoli, Cauliflower & Vegetable Cooling
Freshly harvested broccoli continues to respire after harvest. Rapid removal of field heat can therefore be an important part of post-harvest temperature management.
A vegetable vacuum cooler can provide growers and packhouses with a rapid method of reducing product temperature before cold storage, packing and transportation.
Vacuum pre-cooling can also be suitable for other vegetables, including cauliflower and selected high-moisture produce, depending on the product and application.
Benefits of Vacuum Cooling & Vacuum Chilling
Depending on the product and application, the benefits of industrial vacuum cooling can include:
- Rapid removal of field and product heat
- Cooling cycles measured in minutes rather than hours
- Uniform cooling throughout suitable pallet loads
- Rapid post-harvest pre-cooling
- Faster movement into cold storage
- Improved temperature management
- Support for maintaining product quality
- Potential extension of product shelf life
- Repeatable automatic cooling cycles
- Reduced cooling load on downstream cold storage
- Improved cold-chain efficiency
- High product throughput from a relatively compact cooling system
Intelligent PLC Control
The CC-VC-200 can be supplied with a 12-inch touchscreen HMI and PLC control system designed to provide straightforward operation and clear information throughout each cooling cycle.
Multiple cooling programs can be configured for different products and operating conditions, allowing operators to select the appropriate program for the product being cooled.
This is particularly useful where the same vacuum cooling machine is used for different crops or products.
Manual control backup can also be incorporated into the system.
Smart Remote Monitoring
Cold Change vacuum coolers can be supplied with an optional Smart Monitoring System, providing remote access to important operating and production information.
Depending on the selected specification, this can include:
- Energy consumption
- Cooling cycle times
- Product temperatures
- Service alerts
- Machine alarms
- Breakdown alerts
- Historical operating information
Remote connectivity can also assist Cold Change engineers with machine diagnostics and technical support.
Energy-Efficient Pre-Cooling
Every cooling application is different.
Rather than taking a one-size-fits-all approach, Cold Change can optimise the vacuum pumps, refrigeration system and control program around the customer’s actual product and production requirements.
Factors considered can include:
- Product type
- Product weight
- Starting temperature
- Required final temperature
- Required cooling time
- Number of cycles per hour
- Daily production
- Ambient conditions
Energy-saving options can also be incorporated during system design.
Refrigerant & Low-GWP Options
Cold Change can offer different refrigeration configurations depending on the application, installation country and local requirements.
Lower-GWP and natural refrigerant options can be discussed during system design where appropriate.
Our objective is to provide an efficient refrigeration and vacuum system matched to the customer’s cooling requirements.
Custom Vacuum Cooling Machines
Different growers and processors use different pallet sizes, containers, trolleys and production layouts.
Cold Change can therefore manufacture custom vacuum cooling systems to suit individual applications.
Systems can be designed around specific:
- Pallet dimensions
- Product weights
- Production capacities
- Cooling times
- Loading arrangements
- Factory and packhouse layouts
- Refrigeration requirements
If the standard CC-VC-200 dimensions aren’t suitable, contact us with your product and production requirements.
Need a Different Capacity?

Different cooling technologies suit different products, so Cold Change can help determine whether vacuum cooling, vacuum chilling, blast chilling or hydro cooling is the most appropriate solution for your application.
Scientific Research into Vacuum Cooling
Vacuum cooling has been extensively researched for fresh produce applications including mushrooms, lettuce, leafy vegetables and broccoli.
The technology is particularly interesting for products where rapid and uniform removal of field heat is required following harvest.
