The -30 °C Non-Sealed Recirculating Chiller is an open-tank low-temperature circulation system designed to provide stable cooling for laboratory and pilot-scale applications. The unit creates a controlled low-temperature environment by circulating coolant such as water or glycol-based fluids through connected laboratory equipment.

With a temperature range down to -30 °C, the system provides reliable cooling for processes requiring continuous low-temperature circulation. The chiller uses a high-efficiency compressor, air-cooled condenser, and internally threaded copper evaporator to achieve efficient heat exchange and stable cooling performance.

The open reservoir design allows convenient access to the coolant tank for monitoring, refilling, and maintenance. Equipped with PT100 temperature sensors and multiple safety protections, including overvoltage, overcurrent, overheating, and leakage protection, the system ensures safe and stable operation.

This non-sealed recirculating chiller is widely used with rotary evaporators, glass reactors, condensers, analytical instruments, and other laboratory equipment requiring dependable low-temperature cooling.
