Low temperature screw chillers are widely used in chemical and plastic, electroplating, electronics, chemical, pharmaceutical, food processing, refrigeration and other cooling processes.

 

       ①、The imported international brands BITZER (Germany) and HANBELL (Taiwan, China) high-efficiency energy-saving compressors are used.

       ②、The centralized control of industrial grade PLC units, coupled with the adjustable system of the compressor, can timely and accurately control the matching of the refrigeration capacity and cooling load of the unit, ensuring that the unit operates with optimal efficiency and reducing operating costs. The internal integration includes multiple safety protection and processing functions such as water cutoff, low temperature, high and low pressure, antifreeze, phase loss, delayed start, reverse phase, overload, motor overheating, and oil pressure difference. Full Chinese operation interface, menu type prompt, can set the operation status of the unit at will, and provide a household operating environment.

       ③、Capacity control can adopt four stage (100% - 75% - 50% - 25%) or three stage (100% - 66% - 33%) and stepless control systems;

       ④、The unique built-in oil pressure system ensures that the compressor maintains optimal lubrication without oil pumps. The oil separator adopts a double layer filtering method, providing excellent oil filtering effect, and the heat exchanger can maximize its capacity;

       ⑤、High efficiency internally threaded copper pipe enhances heat transfer effect, making it more energy-saving and efficient. Using the latest CAD/CAM design and processing technology, the CNC machining center has been completed, with a compact structure, small size, and durability. The U-shaped heat exchange tube bundle can be completely extracted to clean the internal scale, facilitating maintenance., Eliminate refrigerant leakage;

       ⑥、The fully imported steel pipes and hyperbolic corrugated hydrophilic aluminum foils are selected and manufactured with professional equipment such as high-speed drilling machines. The steel pipes are in closer contact with the fins, with higher heat exchange efficiency, small size, light weight, and more compact and reasonable structure;
