The -40 °C Sealed Recirculating Chiller is a closed-loop cooling system designed to provide stable and efficient low-temperature circulation for laboratory and industrial equipment. The sealed circulation structure prevents contamination and evaporation of the coolant while maintaining consistent cooling performance and reducing maintenance requirements.

With a temperature range down to -40 °C, the system is suitable for applications requiring precise and continuous temperature control. It uses a high-efficiency compressor, plate heat exchanger evaporator, and intelligent temperature control system to deliver reliable cooling performance and accurate temperature regulation.

The chiller can be connected to equipment such as glass reactors, rotary evaporators, molecular distillation systems, vacuum freeze dryers, condensers, and other laboratory instruments. Its compact design, stable operation, and multiple safety protections make it suitable for chemical laboratories, pharmaceutical research, biotechnology applications, and pilot-scale industrial processes.
