Dhfy Series of Low Constant Temperature Reaction Bath Circulator Pump

Product Description

Thermostatic Water Bath -20℃

Low-temperature constant-temperature reaction baths utilize compressor refrigeration, electric heating tubes for heating, or balanced temperature control. Heat exchange occurs within the liquid storage tank via a heat-conducting medium. The bottom is equipped with a magnetic stirrer (for capacities up to 20L). These baths are primarily used to place containers within the liquid storage tank for chemical reactions or storage operations under constant-temperature, sealed conditions. They can also circulate the heat-conducting medium via a circulation pump to provide a cold source for other instruments and equipment; It is widely applied in various reactors, distillation, or extraction systems, as well as in research institutions, semiconductor and electrical testing, chemistry, pharmaceuticals, petrochemicals, biochemistry, and other fields.

Product Details

Features:

1.Adopts a fully enclosed compressor, which is compact in size, operates smoothly, produces low noise, and has high energy efficiency.
2.Digital display control system, high temperature control accuracy, simple and convenient operation.

3.Magnetic stirring function with adjustable speed, more suitable for low-temperature closed reactions.
4.The evaporator uses stainless steel or purple copper tube coils, which have high heat exchange efficiency. The evaporator is installed in the liquid storage tank, so the evaporator will not be damaged when the heat transfer medium freezes.
