Low temperature circulator
Product Description
Applied in the work need maintain under low temperature conditions of heavy, energy, food, pharmaceutical, biological engineering, metallurgy and other industrial production process.
product Features
- Cycle Cooling medium: HTF, industrial alcohol or water-glycol mixture is circulated against the refrigeration, conservation of resources; tight loop piping design, prevent water pollution cycle, extending the cycle time of the use of water
- Multiple safety protection, more reliable
- Imported compressor, cold cascade refrigeration technology
- Using cold technology to ensure the stability of low temperatures
- It can be set to turn on the compressor and turn off the compressor temperature difference
- Ambient temperature detection function to prevent the system operation environment temperature is too high
- A variety of fault alarm (over-temperature alarm, sensor alarm, high pressure alarm, compressor overheating alarm, level alarm)
- A fully enclosed design, low temperature process without running water, to ensure the purity of the cold heat transfer medium, to prevent ice crystals, providing thermal fluid life
- High-performance circulating pump, can ensure condinuous operation 24 hours a day
- Using cold plate heat exchanger to provide heat transfer efficiency
