Product Description:
low-temperature thermostatic reaction bath is the use of compressor refrigeration, electric heating tube heating or balanced temperature control, Heat exchange occurs in the storage tank through a thermal conductive medium, the bottom is equipped with magnetic stirring (≤ 20L capacity), mainly used for reservoir tanks to place containers, chemical reactions or storage of materials in the constant temperature closed conditions of the chemical reaction or storage operations, but also through the circulating pump delivery of heat-conducting medium to provide a cold source for other instruments and equipment; widely used in Various reactors, distillation or extraction systems, scientific research institutions, semiconductor and electrical testing, chemical, pharmaceutical, petrochemical, biochemical and other fields.
Product Advantages and Features:
- Adopting totally enclosed compressor, small size, smooth operation, low noise, high energy efficiency.
- The air-cooled condenser adopts purple copper tube, finned heat exchanger, high heat transfer efficiency, easy to clean, convenient maintenance.
- Control system digital display, high precision temperature control, simple and convenient operation.
- Magnetic stirring function, speed adjustable, more suitable for low-temperature confined reaction.
- The evaporator adopts stainless steel or purple copper tube coil, with high heat exchange efficiency; the evaporator is installed in the liquid storage tank, and the evaporator will not be damaged when the heat-conducting medium freezes.
- The circulating pump adopts stainless steel shielded pump, which has the advantages of low noise, large flow rate and long durability.
- According to user requirements can be customized water-cooled refrigeration system, explosion-proof models.
