Product description
Water cooled box chiller:
        The water-cooled box type chiller mainly comprises a scroll compressor, a water-cooled condenser, a filter, a liquid path control valve, a thermal expansion valve, an internal thread copper tube evaporator, an electric control system and the like.
1. Scroll compressor: It adopts European and American imported fully enclosed scroll compressors with low noise, high efficiency, low energy consumption, lower failure rate, safe and stable operation, excellent performance and reliability.
2. High-efficiency heat exchange type evaporator/condenser: The washable water-cooled condenser adopts a strengthened internal thread heat exchange copper tube, which is expanded and connected to the tube plate. The water side is designed to have a pressure of 12 bar and the fluorine side is designed to bear a pressure of 25 bar. Safety valves are also available to ensure equipment safety. The evaporator adopts high-quality copper tube with a thickness of more than 1.5mm. The internal thread design, large diameter, large flow and good cooling effect.
3, electrical components control system: imported digital display temperature controller, domestic well-known brand electrical control configuration to ensure safe and stable operation of the unit. Not only the machine life is extended, but also the operation is simple and intuitive;
4. The unit is equipped with single or multiple refrigeration circuits to replace, and independent use has achieved energy saving and environmental protection effects.
5. The unit is equipped with a stainless steel insulated water tank with a sewage discharge port for easy cleaning and disassembly.
6. A number of system safety protection devices, the unit is reliable, stable and automatic, saving human resources. The unit safety temperature control range is 5 °C ~ -40 °C.
7. The whole machine adopts intelligent control, which can automatically adjust energy according to the load size, and detect and balance the running time of each compressor to prolong the service life of the compressor; it can be opened, stopped and remotely controlled in different time periods. Computer or mobile phone networking (optional);
8. and has the following protection functions: a. compressor overload protection b. compressor overheat protection c. high and low voltage protection function d. reverse (lack) phase protection e. compressor start protection f. sensor fault protection g. communication fault protection h. Anti-freeze protection i. Compressor exhaust temperature is too high protection j. Cooling water, ice water flow insufficient protection k. Fault self-diagnosis function l. Cooling water abnormal protection switch h refrigerant abnormal protection switch m antifreeze switch n soluble plug o Overload protection device p coil overheat protector q temperature automatic protection switch r reverse phase protection switch s over voltage, insufficient voltage protection switch. t cooling water pump protection.
9. easy to use and operate; there are two refrigeration circuits, even if one loop fails, the other loop can run as usual.
The casters at the bottom of the body are flexible and convenient to use. Microcomputer control. Simple and intuitive operation.
10. Standard operating conditions of the unit: chilled water inlet temperature 12°C outlet water temperature 7°C, cooling water inlet and outlet temperature 30°C/35°C.
11. the power supply voltage 3 phase 380V 50HZ allows the voltage fluctuation range within plus or minus 10% range.
This series of models can be customized to the ultra-low temperature type discharge temperature can reach (7 ° C ~ -30 ° C)
At the same time, our company designs and produces all kinds of medium and low temperature screw chillers, ultra-low temperature chillers, etc., and can design anti-corrosion chillers and acid and alkali-resistant chillers according to user requirements. Explosion-proof industrial chillers. It can meet the requirements of various industries for process cold sources.
