Low Temperature Cooling Water Circulator

The low-temperature cooling water circulator compresses the refrigerant through a compressor to release heat, and then throttles it through an expansion valve to absorb heat, thereby cooling the circulating water. It is used for constant-temperature cooling of laboratory equipment, such as temperature control for rotary evaporators and reaction vessels.
Selection
When selecting, consider the required temperature range, cooling power and equipment compatibility, check the water pump flow and pressure parameters, pay attention to the corrosion resistance of the tank material, ensure the device dimensions fit the installation space, and verify the power supply voltage compatibility.
