The D5.3E6 cold room evaporator unit is a premier industrial cooling system engineered for medium-and-low temperature environments, delivering optimal performance at a standard holding temperature of -18°C. Outfitted with dual 300 mm heavy-duty external rotor fans, this ceiling-suspended evaporator provides a total air volume of 2*2200 m³/h alongside a dependable 10-meter throw range. It is an ideal B2B cooling solution for medium-sized warehouse lockers, commercial food processing hubs, and logistical walk-in freezers where finding an affordable, high-performing cold room evaporator price point is essential.

Maintaining deep sub-zero environments without incurring excessive electrical bills requires highly advanced internal core physics. The heat exchanger within this unit is constructed with inner-grooved copper tubes arranged in a rigorous staggered-row alignment, which compounds internal surface area and prevents oil film thermal resistance. These lines are mechanically expanded into double-sine wave aluminum fins possessing an open-window profile and a 6.0 mm fin pitch, optimizing continuous air movement and delaying ice-bridge formation.

Built to endure aggressive high-humidity freezing conditions without structural degradation, the outer casing is formed from premium prepainted steel sheets paired with sturdy aluminum tube sheets. This evaporator features an integrated automatic electric defrost system containing specialized stainless steel heating elements distributed through both the coil block and the condensation drainage pan for quick, even ice clearing. To ensure absolute operational safety, each unit clears a strict 2.8 MPa factory clean air pressure test.
