8 Pallet Eco Vacuum Cooler

8 Pallet Eco Vacuum Cooler

This Eco model is aimed at larger fresh-produce operations that need eight-pallet batch capacity while managing vacuum pump demand, refrigeration load and cycle scheduling efficiently.

Eco engineering focus

• Variable-speed vacuum pumping matched to demand
• Refrigeration selection based on actual duty
• PLC/HMI programmes for repeatable product cycles
• Utility and ambient-condition review during project design

Standard versus Eco: loading and cycle scheduling

Compare the eight-pallet Eco design with the standard 8 Pallet Vacuum Cooler against the production profile, not just nominal chamber capacity. An eight-pallet batch may be economical only when incoming pallet spacing and dispatch timing support repeatable loading; evaluate full and partial batches over an actual shift.

Request measured electricity for pumps, refrigeration and auxiliary equipment, kWh per tonne accepted at the required temperature, starting and finishing core-temperature distributions, cooling uniformity and pallet-handling time. Confirm pallet footprint, stacking, vapour release and drainage needs before choosing door layout or conveyor equipment. Final Eco benefits must be demonstrated on the specified duty.

Project sizing

Final configuration will depend on product type, pallet mass, starting and target temperatures, required cycle time and installation conditions. Energy-performance claims will only be published with a documented comparison basis.

The Cold Change 8 Pallet ECO Vacuum Cooler is intended for larger fresh-produce operations that require eight-pallet batches while assessing vacuum-pump demand, refrigeration duty and production scheduling as one complete system.

It should be evaluated alongside the standard 8 Pallet Vacuum Cooler. A meaningful comparison uses the same product, pallet configuration, starting temperature, required final temperature, cooling acceptance criteria and operating shift.

ECO design for higher-throughput batches

At eight-pallet capacity, equipment selection must consider more than chamber volume. Pump response, refrigeration recovery, pallet arrival timing and loading delays can all affect the energy used per accepted batch and the practical number of pallets processed during a shift.

• Variable-speed vacuum pumping selected around the required evacuation profile
• Refrigeration capacity matched to product load and cycle schedule
• PLC and touchscreen HMI programmes for repeatable product recipes
• Assessment of full, partial and mixed production periods
• Review of electrical supply, ambient conditions and daily operating hours
• Monitoring and remote-support options where included in the final specification

No fixed percentage saving applies to every installation. ECO performance should be assessed against the agreed duty using measured total-system electricity, achieved product temperatures, cooling uniformity and accepted throughput.

Production flow and cycle scheduling

An eight-pallet machine can process a substantial batch, but its value depends on coordinated material flow. Pallets should arrive at the chamber in a sequence that supports repeatable loading without unnecessary waiting, while cooled pallets need a clear route to downstream cold storage or dispatch.

Project evaluation should include:

• Pallets or tonnes required per hour and per shift
• Expected harvest or production peaks
• Loading, door-closing, cooling and unloading time
• Availability of full eight-pallet batches
• Frequency and reason for partial batches
• Forklift, pallet-truck or conveyor movements
• Downstream cold-room capacity and dispatch timing

This assessment helps determine whether eight-pallet capacity is appropriate or whether a smaller or larger chamber would provide a better operational fit.

Information required for system sizing

Cold Change can assess the representative cooling duty before confirming vacuum equipment and refrigeration selection. Useful project data includes:

• Product type, packaging and pallet arrangement
• Average and maximum product weight per pallet
• Pallet dimensions and stacking height
• Starting and required final product temperatures
• Required cycle time and hourly throughput
• Daily operating hours and seasonal production variation
• Available electrical supply and installation environment
• Required data, language and remote-access functions

Where energy performance is compared, the basis should state whether the result is electricity per batch, per pallet or per tonne of accepted product at the required temperature.

Products and process suitability

Vacuum cooling is suited to 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 fresh-produce or process applications following technical review

Product trials or validated operating information may be required for unfamiliar loads. Cooling time and final temperature should not be guaranteed before the relevant product and duty information is confirmed.

Controls and operating evidence

The control system can be configured with repeatable programmes for different products and loading conditions. The final sequence coordinates vacuum pumping, refrigeration and product-temperature targets around the agreed process.

Depending on specification, operating records may include cycle duration, product temperature, alarms, service information and energy data. The required measurement points, retention period, user access and remote-support functions should be agreed during project engineering.

Doors, conveyors and chamber integration

The loading arrangement should be selected around the site layout and production flow. Options may include forklift or pallet-truck loading, a single-door chamber, a through-flow arrangement or project-specific conveyor interfaces where technically suitable.

Before final design, confirm pallet footprint, load height, transfer equipment, safety clearances, drainage, cleaning access and service space. Door and conveyor choices should support the required shift throughput rather than being added without an agreed handling plan.

Compare adjacent capacities

The standard 8 Pallet Vacuum Cooler provides the published reference configuration. The ECO model is intended for projects where variable-speed pumping and duty-based energy assessment are priorities.

For lower throughput, compare the 6 Pallet ECO Vacuum Cooler. For larger batches, compare the 10 Pallet ECO Vacuum Cooler. Final selection should be based on the required production rate, loading window and site material flow.
