Product Description:
This equipment is driven by a circulating pump with a single circulating heat transfer medium, which passes through the heater and refrigeration heat exchanger to exchange heat and cold to reach the desired temperature. Closed piping design, high efficiency heat exchanger, reduce the demand for heat transfer fluid at the same time, improve the heat utilization of the system, to achieve rapid temperature rise and fall. It is used to support other instruments and equipment that need to provide hot and cold sources, and is the ideal production equipment for modern fine chemistry, pharmaceuticals and biosynthesis of new materials.
Product advantages and features:
- Thermally conductive medium in a closed system with an expansion vessel, the expansion vessel in the heat conduction medium does not participate in the cycle, whether high or low temperature, expansion tank temperature of room temperature ~ 65 ℃, you can reduce the risk of heat conduction medium in the operation of the absorption of moisture and volatilization.
- Refrigeration can be started directly when the high temperature drops to the low temperature, continuously lifting and lowering the temperature, saving resources and improving work efficiency.
- The heat exchanger adopts fully brazed plate heat exchanger, which occupies little space and has high heat exchange efficiency.
- Circulation pump is high temperature resistant oil pump, with the advantages of high internal temperature, low noise and large flow rate.
- Over-temperature protection, leakage protection, phase sequence protection and other protective functions to improve the safety of the equipment.
- According to the user demand, can be customized water-cooled refrigeration system, explosion-proof models.
