DLS-12EW/EX Low temperature circulator

  • DLS-12EW/EX
Product Description

The liquid circulation of the whole system of the high and low temperature series devices is closed, and the system has an expansion container. The expansion container and the liquid circulation system are adiabatic, which do not participate in the liquid circulation, but only mechanically connected. Regardless of the temperature of the circulating liquid, the medium in the expansion container always keeps room temperature. Since the whole liquid circulation is an airtight system, there is no water vapor absorption at low temperature and no oil mist generation at high temperature. Our company can provide wide working temperature heat conduction oil. so the same machine with the same heat conduction medium can reach  - 80 ℃ ~ 250 ℃ temperature control.  

Product Advantages & Features

1. 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 cycling time .
2. Multiple safety protection , more reliable .
3. Imported compressor,cold cascade refrigeration technology .
3. Using cold technology to ensure the stability when in low temperature reaction .
4. It can be set to turn on or turn off the compressor temperature gap .
5. Ambient temperature detection function to prevent the system operating environment temperature is too high .
6. A varietyof fault alarm ,such as over temperature alarm , sensor alarm , high pressure alarm , compressor overheating alarm and level alarm .
7. A fully closed design , low tempeature process without running water , to ensure the purity of the cold heat transfer medium , to prevent ice rystals , providing thermal fluid life.
8. High-performance circulating pump, can ensure continuous operation 24 hours day .
9. Using cold plate heat exchanger to provide heat transfer efficiency .

Product Applications
Our low temperature circulators are widely applied in heavy chemical industries , mining&energy , food & beverage factory , pharmaceutical plants , biological engineering , metallurgy and other production process which need to maintain under low temperature condition .
