Ultra-low temperature circulation pump

The ultra-low temperature circulation pump cools the refrigerant to below -40℃ through a refrigerant compression cycle and circulates it within a closed pipeline to transfer cold energy. It is used to maintain low-temperature environments for equipment such as reaction vessels and rotary evaporators, making it suitable for scenarios requiring precise temperature control, such as low-temperature material testing and chemical synthesis.
Selection
Select the cooling capacity based on the experimental temperature range, match the equipment interface dimensions, and consider corrosion-resistant materials. Pay attention to temperature stability indicators, verify power parameter compatibility, compare operating noise data, and review safety protection function configurations.
