—— Product Features ——
Withair new Generation air-cooled screw chillers are designed to meet current and future requirements in terms of reliability, energy efficiency and intelligent control. We adopt Environment friendly refrigerants R134a; as for reliability, DX evaporator,which is no oil return problem, we have done 100% run test before the units leave the factory. we adopt Touchable screen display and PLC control s,which are user-friendly operation interface. Twin-rotor screw compressors, more energy efficiency and reliability; Low operating noise Benefit From Low-noise ,low -vibration fans and double-wall structure Hanbell compressor.
We adopt Famous brand Danfoss electronic expansion valve, which is controlled by drive module controller.The drive module controller controls the valve open degree according to evaporator suction superheat temperature;which is Real PID modulation.
The PLC controller reserved RS485 port which can be communicate with BAS (Building Automation system) though the. Modbus communication protocol，as we know our units can be combined by max 12 units to one goup，we need to set the master unit and the slave units on the PLC and then only master unit connect to the Host computer.
