Cooling Unit For Cold Storage

This D10.2E6 cooling unit for cold storage delivers a substantial 10.2 kW nominal cooling capacity designed for demanding commercial freezing applications. The unit features a staggered internal copper piping design using inner-grooved tubes paired with window-cut, dual sine wave louvered fins to maximize heat transfer surface area and break down oil film thermal resistance. Driven by dual 400 mm external rotor fans, the system pushes a high-volume 7800 m³/h airflow with a powerful 10-meter horizontal throw, ensuring rapid temperature pull-down and complete cold air coverage across dense inventory setups.

Maintaining uninterrupted performance at a -18°C room baseline requires specialized defense against ice accumulation. This industrial evaporator integrates an extra-wide 6mm (4 FPI) fin spacing layout. This wide structural layout accommodates massive frost deposits during frequent loading dock doors openings without narrowing air channels or causing system static pressure drops. It allows the refrigeration plant to maintain high efficiency and prevents premature compressor short-cycling.

Engineered to maximize overhead room efficiency, this low-profile unit mounts flush against the ceiling panels to stay entirely clear of forklift paths and vertical storage racks. The heavy-duty casing is constructed from premium galvanized steel treated with a highly anti-corrosive powder coating. Internally, two 180W low-temperature motors feature IP55 waterproof protection and Class F electrical insulation to handle continuous sub-zero humidity. Verified by a 2.8 MPa clean air pressure leak test, the coil ensures long-term reliability with R404A, R507A, R23, R134a, and R22 refrigerants.
