Features

High reliability

The screw compressor has few parts, no wearing parts, stable and reliable operation, and long life.

The screw compressor adopts a new generation of high-efficiency 5:6 patented asymmetric tooth design to improve work efficiency.

The screw compressor with positive displacement design has small clearance volume, low friction loss and high operating efficiency.


Compressor

The refrigerant circuit and the control circuit are completely independent, and can be used alternately according to load conditions, effectively prolonging the service life of the unit. It has the advantages of high efficiency, low energy consumption, low noise, low vibration, wear resistance, and high reliability.


Condenser

Shell and tube condenser, the heat exchange tube is an outer finned copper tube, and the cover plates at both ends are removable, and the copper tube can be removed for cleaning. The condenser shell is equipped with fusible plugs to effectively ensure the safe operation of the system. The condenser has passed the national pressure vessel inspection.


Evaporator

The shell-and-tube evaporator uses inner finned copper tubes and is equipped with a refrigerant diversion device, which can evenly distribute the refrigerant to the heat exchange tubes and improve the heat exchange efficiency. For multi-compressor chillers, each compressor is equipped with an evaporator and a condenser, and the three constitute an independent refrigeration system. Due to structural reasons, the water paths of the two evaporators are often connected, while the refrigeration circuit is independent. Thermal insulation materials are attached to the outside of the evaporator to avoid loss of cooling capacity.


Thermal expansion valve

Using the world-renowned brand Emerson thermal expansion valve, the control accuracy is higher, the adjustment range is wider, and the response is faster. Under any working conditions, the heat exchange area of the evaporator can be fully utilized, the heat exchange is more sufficient, the efficiency is higher, and the reliability of the refrigeration system can be guaranteed.


Control System

Start-stop protection, control compressor start frequency

Equivalent setting of compressor start and stop times and running time

Touch screen controller

Remote monitoring can be added and RS485 communication interface is provided.

Power-off memory, historical fault query function

Overload protection, phase sequence protection, antifreeze protection, high and low pressure protection, exhaust temperature protection.

Inlet and outlet water temperature control

Monitor the inflow and outflow water flow

Reserve the chilled water pump, cooling water pump, and cooling tower joint control contacts.
