Air Cooler For Cold Room
Product Advantages
Steady Temperature Control for Frozen Storage

Keeping medium-to-low temperature storage spaces at a stable -18°C requires consistent, reliable circulation. The D7.7E6 air cooler for cold room uses dual 400 mm external rotor fans to distribute cold air evenly across storage racks. By providing a broad air throw of up to 10 meters, this air cooler for cold room eliminates warm pockets and dead zones, ensuring reliable temperature consistency for food processing plants and distribution hubs.

Optimized 6.0 mm Fin Spacing to Reduce Frost Build-up

Frost build-up is a constant challenge for operators running continuous sub-zero operations. This air cooler for cold room features an inner-grooved staggered copper tube design paired with a wide 6.0 mm fin pitch. The wider fin spacing significantly delays frost bridging between the aluminum fins, reducing the frequency of energy-consuming defrost shutdowns and keeping the heat transfer rate high even under heavy cold storage loads.

Heavy-Duty Casing and Split Defrosting

Designed to withstand humid freezing environments, the outer casing is built from corrosion-resistant prepainted steel and rugged aluminum sheets. To make maintenance simple, the 4.7 KW electric defrost system is strategically split between the main evaporator coil and the drain pan, preventing melted ice from refreezing during discharge. To ensure absolute field reliability, every unit is pressure-tested at 2.8 MPa before dispatch.

Frequently Asked Questions
Q1: How does the staggered tube pattern inside the D7.7E6 improve thermal performance?
Staggering the copper tubes forces the passing air into a curved, wavy flow path. This increases the contact time between the air and the cold tube surfaces, boosting overall heat transfer efficiency compared to standard inline configurations.
Q2: What advantages do the dual 400 mm external rotor fans have over traditional internal rotor motors?
External rotor motors are integrated directly into the fan blade hub. This compact design results in higher mechanical efficiency, better heat dissipation, and a more compact footprint, while still delivering a powerful 10-meter air throw.
Q3: Why is the drainage pan equipped with its own independent defrost heating elements?
During a defrost cycle, melted frost runs down into the cold drain pan. Without a dedicated heater in the pan itself, this water would instantly refreeze and clog the 1" drain line. The separate heater keeps the pan warm enough to ensure complete drainage.
Q4: What is your warranty policy for commercial refrigeration projects?
We provide a 1-year warranty on all evaporator units, which covers manufacturing defects. We also maintain a rapid-response parts replacement service to minimize downtime for your cold storage operations.
Q5: What is the typical lead time for an order of 10 to 20 evaporator units?
Standard models can be assembled, pressure-tested, and ready for shipment within 10 to 15 business days. If custom shell materials (like stainless steel) or non-standard voltages are requested, the lead time is typically extended by an additional 5 working days.
