1. Circulating cooling medium: HTF, industrial alcohol or water-glycol mixture for circulating , conservation of resources.
2. Tight loop piping design, prevent cooling medium pollution, extending the cycle time of the use of cooling medium.
3. Multiple safety protection, more reliable.
4. Imported compressor, cold cascade refrigeration technology.
5. Using cold technology to ensure the stability of low temperatures.
6. It can be set to turn on the compressor and turn off the compressor temperature difference.
7. Ambient temperature detection function to prevent the system operating environment temperature is too high.
8. A variety of fault alarm( over-temperature alarm, sensor alarm, high pressure alarm, compressor overheating alarm, level alarm)
9. A fully enclosed design, low temperature process without water absorbtion, to ensure the purity of the cooling medium, to prevent ice crystals, prelong cooling medium life.
10. High-performance circulating pump, can ensure continuous operation 24 hours a day.
11. Using cold plate heat exchanger to provide heat transfer efficiency.
