1 Pallet Eco Vacuum Cooler

1 Pallet Eco Vacuum Cooler

The Cold Change 1 Pallet Eco Vacuum Cooler is part of the Cold Change Eco vacuum cooling range, developed for compact specialist growers, pilot-scale production, research and lower-volume packhouses.

The Eco concept is intentionally separate from the standard 1-pallet product page. Its search and product positioning will focus on energy-efficient vacuum cooling, variable-speed vacuum pumping and application-matched system design, while the established standard page continues to target the core 1-pallet vacuum cooler search.

Standard and Eco design comparison

For a single-pallet project, compare complete-cycle electrical demand at the same compact load and product-temperature target. Limited space, lower daily cycle count and changing product batches may matter more than headline pump capacity.

Planned Eco engineering focus

• Variable-speed vacuum pump configuration matched to operating demand
• Cooling-cycle control based on product and process requirements
• Refrigeration duty selected around the actual cooling load rather than a generic one-size specification
• PLC/HMI control with repeatable product programmes
• Project-specific review of electrical supply, ambient conditions, batch mass and throughput

1 pallet project sizing

Final equipment selection will depend on pallet dimensions, product type, mass per pallet, starting temperature, target temperature, required cycle time, cycles per hour and site conditions. The 1-pallet Eco page will therefore be built around engineering selection rather than an unsupported fixed performance claim.

Energy-efficiency wording

The page will describe the engineering measures used to reduce unnecessary energy demand, but no fixed percentage saving will be published until the supporting evidence, test conditions and comparison basis are documented.

Request a project assessment

Customers considering a 1-pallet Eco vacuum cooler will be asked for the same project inputs used for a standard industrial vacuum cooling assessment so the final system can be matched to the real duty.

The 1 Pallet ECO Vacuum Cooler is the compact ECO option for pilot-scale cooling, specialist crops, small production batches and operations whose throughput varies from day to day. It is intended for projects where a single-pallet chamber is the right physical fit and where pump control, site services and operating pattern need to be considered together rather than reduced to a headline energy figure.

Where a single-pallet ECO system fits

A one-pallet chamber can suit growers, packers, research teams and product-development sites that need repeatable vacuum-cooling cycles without installing a larger chamber than their normal batch size requires. Typical project questions include how often the cooler will run, whether batches are full or partial, the temperature and moisture condition of incoming product, the target temperature, and how quickly the next batch must be ready.

The ECO configuration is most relevant when utilisation is low or variable, when the cooling load changes between products or seasons, or when the site wants the pump package selected around actual duty rather than a single fixed operating point. It is not automatically the best choice for every one-pallet project: the conventional 1 pallet vacuum cooler remains the direct comparison where a simpler standard arrangement better matches the operating pattern.

Variable-speed pumping and project-specific control

The ECO concept uses variable-speed pump control so the pumping system can be configured around the required cycle and load profile. The practical benefit depends on the complete design: product, batch mass, starting temperature, target temperature, chamber leakage, refrigeration duty, ambient conditions, cycle frequency and the site’s electrical supply all matter. Cold Change therefore treats energy use and cycle performance as project calculations, not universal promises.

Controls can be arranged around validated recipes for different products or batch conditions. That supports repeatable operation while still allowing commissioning adjustments to suit the real product and site. The final pump arrangement, refrigeration package and controls are specified during quotation.

Products and applications

Vacuum cooling is commonly assessed for produce and materials that can release moisture under reduced pressure. Depending on the crop, packaging and process, applications may include mushrooms, lettuce, broccoli, cauliflower, celery, cut flowers and turf. Suitability should be confirmed against the actual product, harvest condition, packaging and quality objective.

A single-pallet machine is especially useful when the project needs contained trials or small commercial batches. It can also provide a practical basis for establishing recipes before a later capacity decision, although results and scale-up requirements must be reviewed for each product rather than assumed.

Site and chamber considerations

• Batch format: pallet footprint, maximum load height, gross pallet mass and whether partial pallets are expected.
• Product condition: incoming temperature, target temperature, field heat, moisture condition and packaging airflow.
• Operating pattern: batches per hour or shift, seasonal peaks, changeovers and acceptable cycle window.
• Utilities: available electrical supply, ambient design conditions, water arrangements where applicable and heat-rejection location.
• Handling: loading direction, door arrangement, forklift or pallet-truck access and available floor space.
• Controls: recipe requirements, operator access, data needs and integration with the wider packing process.

These inputs determine whether the 1 Pallet ECO model is the right fit and prevent a compact chamber from being selected without enough pumping or refrigeration capacity for the intended duty.

Choosing between one and two pallets

If two pallets are routinely available together, or the required throughput leaves little recovery time between single-pallet cycles, compare this model with the 2 Pallet ECO Vacuum Cooler. Chamber utilisation, handling time and the upstream packing flow can matter as much as nominal chamber size. Where batches are genuinely small or intermittent, the one-pallet format may avoid unnecessary chamber volume and keep the installation compact.

Information needed for a quotation

For a useful technical proposal, provide the product or crop, typical and maximum pallet weight, pallet dimensions, starting and target temperatures, desired cycle time, batches per hour or shift, site voltage and frequency, ambient design conditions, and any restrictions on space or loading. Cold Change can then assess the chamber, pumping, refrigeration and controls as one system.
