Features of Refrigerated Circulators

Saving resources. Closed cycle pipeline design highly prevent circulating water pollution and extend the lifetime of circulation liquid.
Multi-safety protection, more reliable operation.
Brand compressor, cascade refrigeration cooling technologies.
Human design, more convenient and flexible.
Efficient two-condensate system.
Computer-cascade temperature controller,temperature figures display, adjustable unit is 0.1°C, PT100 temperature sensor.
Can set the temperature difference of compressor on/off.
Monitoring the ambinet temperature, prevent temperature to be higher in the running system.
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.

Advantages of Refrigerated Circulators

LNEYA specializes in the development and production of low-temperature refrigerationcirculators. The refrigeration temperature ranges from-125°C to +30℃. Adopt a computercascade temperature controller and a PT100 temperature sensor with high temperature controlaccuracy. The product uses a mixture of ethylene glycol and water for cyclic refrigeration, saving water resources.
Adopt supercooling technology to ensure temperature stability at lowtemperatures; adopt a fully enclosed design to ensure the purity of the cold heat transfermedium, prevent ice crystals, and increase the life of the heat transfer fluid.
The product adopts the international brand compressor Carlyle, which is small in size and high in efficiency. The single compressor can realize the temperature control of -152 °C, and the ultra-low temperature refrigeration technology is at the international advanced level.
