4-Fan Cold Storage Unit Cooler

Typical Applications

Fresh produce storage is one of the most demanding cold chain applications because living crops keep respiring after harvest and lose value with every degree of poor temperature control. This unit cooler serves apple and pear controlled-atmosphere anterooms, stone fruit hydro-cooling lines, lettuce and broccoli vacuum-cool buffer rooms, potato and onion curing stores at higher setpoints, and mixed-commodity distribution warehouses supplying retail chains. It also fits flower cold rooms and mushroom growing support spaces. Where a facility stores multiple commodities through the year, the unit’s wide operating flexibility lets one room switch between product types with control setting changes rather than hardware changes.

Why Airflow Design Decides Produce Quality

Produce rooms fail product first, not equipment first – and the failure mode is usually uneven temperature. Warm pockets near doors or ceiling corners accelerate ripening and decay, while air that moves too fast across open bins strips moisture and causes weight loss the grower sells by. This unit’s four-fan layout spreads airflow along the full coil width and throws it the length of the room, keeping temperature variation low without concentrated high-velocity streams. During defrost, the choice between electric, water and hot-gas methods determines how quickly the coil returns to duty and how much heat leaks into the room; produce rooms at 0°C to +4°C benefit from fast defrost with minimal temperature swing. Our engineers model air distribution for your room geometry and stacking pattern so the cooling system protects the crop, not just the setpoint.

Manufacturing Quality and Project Support

Every unit is assembled with mechanically expanded copper tubes, pressure-tested circuits and balanced fan sets, then inspected against its rated airflow and capacity. Drain pans are sloped for full drainage, and heater positions are verified for even frost melt. Arteco provides room-level engineering including unit placement, throw direction and defrost scheduling, and supports commissioning so the store reaches stable conditions before the first harvest delivery.

Frequently Asked Questions

What storage volume does this unit cooler serve?

As a guide, 18–25 kW capacity serves produce rooms of roughly 200–600 m³ depending on commodity, packaging and door activity. Share your commodity, room dimensions and target temperature through our RFQ form for a confirmed selection.

Which defrost method is best for vegetable storage?

For rooms near 0°C with high humidity, hot-gas or water defrost minimizes temperature swing and keeps humidity stable. Electric defrost suits rooms with scheduled defrost windows. We select the method with your operating routine in mind.

Can the unit handle rooms with controlled-atmosphere support?

Yes. The unit integrates with CA room arrangements; fan operation during CA periods can be managed through the control system, and construction materials are compatible with standard CA environments.

Is stainless construction worth it for produce warehouses?

Where rooms are washed between campaigns or store high-acid commodities, stainless casings resist corrosion and extend service life. For dry-storage commodities like onions, galvanized construction is typically sufficient. We recommend based on your hygiene program.
