Temperature Controlled Water Circulator

Contact us today for the perfect temperature control solution

The temperature controlled water circulator is a device used in laboratories, medical, chemical and other fields to provide precise temperature control and constant circulating water flow. These equipment usually consist of compressors, condensers, evaporators, water pumps, regulating valves and thermostats.

The temperature controlled water circulator can maintain a constant temperature between -100°C and +300°C, and circulate the constant-temperature liquid back to the experimental device through a built-in circulating water pump. This type of equipment typically comes with a digital display and control panel that makes it easy to set and maintain the desired temperature and flow rate.

Operating principle of cryogenic cooling circulator

1. Components: compressor, condenser, evaporator, fan (internal and external) circulating water pump, stainless steel liner, heating tube, intelligent temperature control meter.

2. After the compressor is running, it undergoes suction-compression-exhaust-condensation-throttle-then low-temperature evaporation and heat absorption and vaporization. The water temperature is reduced to the temperature set by the temperature control meter. If the temperature set by the temperature control meter is higher than Normal temperature. The contactor in the temperature control meter works automatically, giving the heating tube a current signal, and the heating tube starts working when the low-temperature cooling circulator is working. The inlet and outlet of the whole machine can be used to circulate the water source inside the machine internally or externally, or the water source inside the machine can be directed outside. Create a second constant temperature field outside the low-temperature constant temperature bath.

The main applications of temperature controlled water circulators include cooling samples, controlling reaction rates, maintaining stable temperatures in laboratory equipment, processing biological samples, and preparing chemical reagents. In addition, they can provide stable temperatures during temperature-sensitive processes such as DNA amplification, PCR reactions, and protein crystallization experiments.

In general, the temperature controlled water circulator is one of the indispensable devices in laboratories and industries. It can provide scientists, doctors and engineers with precise temperature control and constant circulating water flow to help them complete various experiments. and research work.
