      The heart of MK series water-cooled screw chillers is an imported high-quality screw compressor with outstanding performance of high-efficiency double screw rotors, which is 20% - 30% more efficient than ordinary compressors. It is reliable in operation, high in efficiency, easy to maintain, precise in energy control, and has a wide range of applications. 1. High quality asymmetric rotor tooth shaped twin screw; 2. Four stage or non stage capacity regulation; 3. Built-in differential pressure oil supply and lubrication system; 4. Low vibration, low noise.

    The unit adopts a programmable microcomputer controller to accurately control the inlet and outlet water temperature. It adopts a large LCD touch screen with a good human-computer dialogue interface in Chinese, which can fully realize automatic control of the unit. The LCD screen instantly displays the unit's working status and real-time monitors the unit's operating status.

    Graded and stepless energy control, used in general process refrigeration or air conditioning systems, is equipped with 100%, 75%, 50%, and 25% graded energy control systems, which can ensure stable operation of the unit under partial load. If more accurate control of water temperature is required, a stepless energy control system can be installed according to user requirements to control the cooling output in real time, achieving efficient and energy-saving operation, and accurately controlling the water temperature.

   The heat exchanger of the unit adopts high-quality and efficient internal thread heat exchange copper tubes, which fully exchanges heat with the cooled medium, ensuring high heat exchange efficiency and efficient operation of the unit; The unit is equipped with reliable safety protection and auxiliary components to monitor the operation status of the unit in real time. Specific protection measures include: compressor protection timer, overcurrent relay, compressor motor temperature sensor, field of view mirror, oil heater, compressor reverse protection relay, exhaust high temperature protection, safety valve, soluble plug, etc.
