The FNV series double-layer box-type condenser (three motors) features a double-layer air inlet box structure and is equipped with three independently driven axial fans, enabling multi-stage speed control. The outer shell is typically constructed of galvanized iron, spray-coated steel, or stainless steel. Internally, it houses a copper-tube, aluminum-fin heat exchanger, compatible with refrigerants such as ammonia and Freon. The unit offers three adjustable air volume settings: high, medium, and low. The fan start/stop and speed can be automatically or manually adjusted based on ambient temperature and system load. Suitable for medium to large refrigeration systems, it maintains stable condensing pressure and heat exchange efficiency even in high ambient temperatures or with limited ventilation.
