low temperature thermostatWidely used in sample pretreatment, instrument constant temperature, reaction control and other experiments in the fields of chemistry, biology, materials, medicine, etc.

　　low temperature thermostatThrough the collaborative work of refrigeration system, heating system, temperature control system, and circulation system, precise temperature control is achieved:

Refrigeration system: Adopting a compression refrigeration mechanism for cooling, the refrigerant is compressed into high-temperature and high-pressure gas through components such as compressor, condenser, evaporator, and throttle valve. After condensation and heat dissipation, it becomes high-pressure liquid, which is then throttled and depressurized into low-temperature and low-pressure liquid. It absorbs heat from the surrounding medium and evaporates into gas, achieving the refrigeration effect.

Heating system: composed of heating elements and control circuits. When the temperature is lower than the set value, the heating elements are activated to raise the temperature.

Temperature control system: Real time monitoring of the temperature inside the tank through temperature sensors and transmission of signals to the controller. The controller compares the actual temperature with the set temperature and controls the operation of the cooling or heating system to maintain the temperature within the set range.

Circulating system: composed of a circulating pump and pipelines, it circulates the cooling liquid in the tank, ensures uniform temperature distribution, and can be transported to external equipment for temperature control.

Maintenance of refrigeration system: When not in use for a long time, the medium in the tank should be emptied to keep the equipment dry; Regularly check the refrigerant pressure of the compressor, and repair it promptly if there is a leak.

Regular cleaning: The interior of the tank needs to be cleaned regularly to prevent medium contamination or scaling from affecting heat exchange efficiency; The cooling fins of the condenser should be kept clean to avoid dust accumulation and affect the cooling effect.
