liquidfor the chemical industryfor the pharmaceutical industry

1.Temperature ranges from -5℃ ~ -150℃, can meet different temperature 2. Famous brand semi-closed piston compressor, semi-closed bipolar piston compressor, semi-hermetic screw compressor, main brand are BOCK. Bitzer, Copeland, Handbell, fusheng; Plate heat exchanger, Small volume, High efficiency 3. Top imported cold controller; Generator cooling water circuit uses intermediate heat exchanger, improve system reliability and safety. 4. DANFOSS electronic expansion valve, high precision control; 5. Adopt Siemens PLC S7-200/300, LNEYA touch screen, automatic control, temperature curve display, temperature record U disk, fault alarm; 6. Offer machine installation and system test, users only need to finish the installation of refrigerant and cooling water; After running for a period of time, the normal operation of ultra-low temperature circulating water chiller needs comprehensive maintenance and maintenance. For many enterprises, due to the weak consciousness of daily maintenance, the cryogenic cycle water chiller has been used for a long time without maintenance. If the low-temperature cycle chiller is lack of necessary maintenance, the failure rate of the ultra-low temperature circulating water chiller will be pretty high in the later period. There will be a large range of incrustation problem after an industrial long-term cryogenic operation of circulating water chiller. If the incrustation cannot be effectively cleaned up, the range of incrustation will continuously extend after a long time of accumulation, which will directly affect the industrial circulation chillers of ultra-low temperature.
