2 Pallet Eco Vacuum Cooler
This Eco model is designed for smaller and growing packhouses that need two-pallet batch capacity while keeping the system footprint and utility demand under close control.
Standard and Eco design comparison
For two-pallet projects, evaluate whether shorter runs, regular product changeovers and partial loading justify a variable-speed evacuation strategy. Any comparison should use the same actual pallet mass, packaging and achievable product-temperature result.

Eco engineering focus
- Variable-speed vacuum pumping matched to operating demand
- Cooling programmes set around product and process requirements
- Refrigeration duty selected around the real cooling load
- PLC/HMI control for repeatable cycles
Project sizing
Final equipment selection will depend on pallet dimensions, product type, mass per pallet, starting and target temperature, required cycle time, cycles per hour, electrical supply and ambient conditions. No fixed percentage energy-saving claim will be published until the supporting evidence and comparison basis are documented.
The Cold Change 2 Pallet ECO Vacuum Cooler is an application-engineered configuration for smaller and growing packhouses that need two-pallet batch capacity, repeatable cooling programmes and closer control of electrical demand.
It should be compared with the standard 2 Pallet Vacuum Cooler using the same product, pallet mass, packaging, starting temperature, required final temperature and production schedule.
ECO engineering for smaller batch operation
Two-pallet installations may operate with shorter production runs, frequent product changeovers or a mixture of full and partial batches. The ECO approach is intended to coordinate variable-speed vacuum pumping, refrigeration and controls around the verified duty instead of relying on nominal motor ratings alone.
- Variable-speed vacuum pumping selected for the process requirement
- Refrigeration capacity matched to product load and temperature reduction
- PLC and touchscreen HMI programmes for repeatable cycles
- Assessment of full-load, single-pallet and seasonal operation
- Review of electrical supply, ambient temperature and operating hours
- Monitoring or remote-support options where included in the specification
No universal percentage saving applies to every site. Any standard-versus-ECO comparison should state the product, load, temperature duty, cycle result and measurement basis.
Where two-pallet capacity can fit
A two-pallet chamber can suit farms, packhouses, trial facilities and specialist producers that need more throughput than a single-pallet system without moving directly to a larger chamber. It may also suit operations where different crops or batches must remain separated.
Practical throughput depends on cooling time, loading and unloading time, incoming product temperature, working hours and the number of batches required during peak periods. Machine selection should therefore be based on kilograms or pallets per hour rather than capacity per cycle alone.
Information needed for correct sizing
Cold Change can assess the representative operating duty before confirming pump and refrigeration selection. Useful project information includes:
- Product and packaging type
- Pallet dimensions and product weight per pallet
- Starting and required final temperatures
- Required pallets, kilograms or tonnes per hour
- Expected number of cycles and daily operating hours
- Frequency of full and partial loads
- Seasonal production peaks
- Available electrical supply and installation conditions
This information allows the proposed ECO configuration to be assessed against the actual cooling process and site utilities.
Products and cooling suitability
Vacuum cooling is suitable for products that can release a controlled amount of moisture under reduced pressure. Product structure, packaging and the required temperature reduction must be reviewed before cycle performance is specified.
- Mushrooms
- Lettuce and leafy vegetables
- Broccoli
- Cauliflower
- Celery and selected vegetables
- Cut flowers
- Turf
- Other suitable products following technical assessment
Product trials or validated operating information may be required for unfamiliar loads. Cooling time and final temperature should not be guaranteed until the relevant duty data are confirmed.
Controls and operating records
The control system can be configured with repeatable programmes for different products and load conditions. The final sequence coordinates vacuum pumping, refrigeration and product-temperature targets around the agreed process.
Depending on the selected specification, operators may be able to review cycle duration, product temperature, alarms, service information and energy data. Required languages, user permissions, records and remote-support functions should be agreed during project engineering.
Installation and material handling
A compact system still requires suitable access, safe clearances and integration with the surrounding process. Project planning can include:
- Forklift or pallet-truck loading access
- Single-door or alternative loading arrangement where applicable
- Equipment service and maintenance clearances
- Drainage and cleaning requirements
- Interfaces with packing and downstream cold storage
- Refrigerant and electrical requirements for the installation country
Compare adjacent capacities
The standard 2 Pallet Vacuum Cooler provides the reference product configuration. The ECO version is intended for projects where variable-speed pumping and duty-based energy evaluation are priorities.
For smaller batches, compare the 1 Pallet ECO Vacuum Cooler. For increased throughput, compare the 4 Pallet ECO Vacuum Cooler. Final selection should be based on the required production rate and available loading window.
