LNEYA specializes in the production of cryogenic circulators, a very wide refrigeration temperature range, and a controllable temperature of -120 ~ 30℃. It adopts secondary sub-cooling, fast cooling speed, safe and reliable, and is used for rapid liquid cooling. It is widely used in high-tech industries such as petrochemical, medical, pharmaceutical, biochemical, freeze-drying, pharmaceutical and so on.
Advantages of Low Temperature Recirculating Chiller
- Saving resources. Closed cycle pipeline design highly prevent circulating water pollution and extend the lifetime of circulation liquid.
- Brand compressor, cascade refrigeration cooling technologies.Human design, more convenient and flexible.
- Computer-cascade temperature controller,temperature figures display, adjustable unit is 0.1°C,temperature. range is -120°℃~30°C, PT100 temperature sensor.
- A variety of fault alarm (over-temperature alarm, sensor alarm, high pressure alarm, compressor over heat alarm,liquid level alarm).
- Power on delay protection, three-level cascade system protectors.All parts are safety grounding.
- Adopt full closed circulation design, no water vapor at low temperature and ensure the purity of cooling medium, in case of ice crystals, provide a long time life of heat transfer liquid.
- High-performance circulating pump, can guarantee 24 hours continuously running a day.Use plate cool-heat-exchanger, heat transfer efficiency is provided.
