Scope of application: industrial cryogenic refrigeration
1. The core components of GSL series low-temperature chiller adopt internationally famous brand fully-closed piston, semi-closed piston or semi-closed screw low-temperature refrigerant compressors;
2.The refrigeration components are all international brands such as Emerson, Castrol, Danfoss, etc., with high efficiency, stable work and long life;
3. High-efficiency shell-and-tube condenser and evaporator, supplemented by expansion valves, gas-liquid separators, oil coolers and liquid storage systems dedicated to low-temperature chiller, and PLC humanized operation control system is perfected, which can meet various requirements A required low-temperature freezer;
4, using a microcomputer control system, independently developed, customized by well-known manufacturers, with ultra-high and low temperature display and signal output protection, with normally open and normally closed output for selection;
5. The electrical part adopts original products of international brands such as Schneider and Omron, with high quality, stable performance and long life;
6, the machine is equipped with compressor overload protection, water pump overload protection, high and low pressure abnormal protection, flow, oil pressure and other protection devices and abnormal alarm buzzer indicator, the circuit can automatically cut off, safe and reliable.
7. GSL low temperature chiller is roughly divided into H (high temperature), M (medium temperature), and L (low temperature) series according to different temperature requirements. Its refrigerant evaporation temperatures are -5 ° C, -10 ° C, and -20 ° C. The compressors and other spare parts configured for different series units are different, and the capacity of the same compressor under different operating conditions is also different. Therefore, when selecting models, you should find the equipment series corresponding to the corresponding operating conditions. In order to prevent the freezing water of the evaporation system from freezing, a glycol solution must be added to the frozen water system. The concentration of glycol must not be lower than 20% (H series), 30% (M series) or 40% (L series). To ensure the normal operation of the chiller. According to the special requirements of the user, after changing the corresponding configuration, the unit with an evaporation temperature as low as -40 ° C can be customized.
