KAIDELI KUDJ Series Low-Temperature Ceiling Unit Coolers with Electric Defrost
Product Description
The KAIDELI KUDJ Series comprises ceiling-mounted unit coolers designed for low-temperature freezer rooms and frozen-storage applications.
The series uses a wide 9.0 mm fin spacing to provide greater frost clearance under low-temperature operating conditions. The heat exchanger combines staggered copper tubes with aluminium fins and mechanical tube expansion for dependable contact and efficient heat transfer.
Low-noise external-rotor axial fans provide high airflow and long air throw. Stainless-steel tubular heaters are distributed through the coil and drain-pan area to promote fast, uniform defrosting and reduce secondary icing.
The coil is factory air-tightness tested at 2.6 MPa. Aluminium-sheet and powder-coated steel casing options are available for different installation environments.
Final selection must be verified according to the required room temperature, refrigeration load, refrigerant and ambient conditions.
