AirBoost Air-Cooled Screw Chiller Model Indirect free cooling series, SCAF***HV(FC-I) 460V-3Ph-60Hz

.

Description

High-efficiency screw compressor

The screw rotor adopts the optimized design of the compression process, which not only ensures excellent volumetric efficiency, but also reduces the leakage of the compressor. The twin screw rotor adopts the asymmetric design of five to six teeth, the machining precision is up to the micron level, stable and reliable

High-capacity inverter motor design and refrigerant cooling, high motor efficiency. The screw rotor is directly driven by the motor, has fewer moving parts and wearing parts, has high mechanical efficiency

The compressor is specially designed to work with the latest variable frequency technology. It operates freely from 25Hz to 70Hz, has high part-load energy efficiency


High efficiency air side heat exchanger

High efficiency and low noise axial flow fan. The fan impeller design is optimized by professional flow field software to ensure good aerodynamic performance of the impeller, which ensures that the fan operates with low noise and at the same time receives a larger air volume and improves the air side heat transfer effect.

Reverse M-type air-side heat exchanger, the air flow is evenly distributed to achieve high-efficiency heat exchange

High-efficiency internal thread tubes and high-quality arc-shaped window aluminum fins are brought together by mechanical expansion tube to improve heat transfer efficiency, reduce pressure drop and wind noise

Professional temperature field simulation, optimal design


High-efficiency flooded evaporator

The refrigerant distributor can distribute the refrigerant evenly, optimize the temperature field, and improve the evaporation temperature, so as to improve the operating efficiency.

Specially designed baffle plate to prevent compressor from being sucked in with liquid, improving the reliability of the machine

 

The water box at both ends can be removed for easy maintenance
