Product Specification
| High Light | low temperature refrigeration evaporator ，ceiling refrigeration evaporator D7.3E9 ，D7.3E9 ceiling evaporator with warranty | ||
The D7.3E9 is a ceiling-mounted unit cooler specifically designed for low-temperature cold storage facilities, deep-freezing rooms, and industrial food processing applications operating at room temperatures down to -35°C. Delivering a nominal cooling capacity of 7.3 kW, this refrigeration evaporator ensures continuous, efficient thermal drawdown to maintain cargo freshness and prevent temperature fluctuations.
In low-temperature freezing environments, rapid frost buildup on evaporator coils frequently leads to airflow restriction, extended defrost cycles, and excessive power draw. The D7.3E9 resolves these operational issues through a wide 9 mm fin pitch (3 FPI) structure coupled with three φ400 mm low-temperature axial fan motors. This configuration produces a strong air volume of 11,700 m³/h with an air throw distance of 10 meters, delaying frost bridge formation while guaranteeing uniform air circulation across the storage room.
Built with high-grade stainless steel heating elements, insulated connectors, and low-temperature epoxy-encapsulated wiring, the D7.3E9 incorporates an 8.5 kW electric defrost system with dedicated heating tubes in both the fin block and drain pan for complete ice removal. Each coil is factory pressure-tested with clean air at 2.8 MPa, features IP55 waterproof fan protection, and supports multi-refrigerant compatibility including R507A, R404A, R23, R134a, and R22.
