Low-temperature Coolant Circulator

The low-temperature cooling liquid circulator compresses the refrigerant through a compressor to release heat, and then cools the circulating liquid by throttling and absorbing heat via an expansion valve. In the laboratory, it provides continuous low-temperature cooling for equipment such as reactors and rotary evaporators, enabling temperature control for reactions or condensation recovery of solvents.
Selection
When selecting, consider the required temperature range, cooling power, and compatibility with the equipment. Check whether the flow rate and pressure of the circulating pump meet the pipeline requirements. Pay attention to the tank volume and its suitability for the experimental scale. Confirm the temperature control accuracy and stability. Review safety protection features such as liquid level alarms and overload protection.
