HNZXIB GDX-5/10 Heating Cooling Circulator -9~199°C laboratory supply

Heating Cooling Circulator

The HNZXIB GDX-5/10 is a laboratory heating and cooling circulator that integrates a low-temperature pump with a high-temperature oil bath. It delivers a sealed liquid circulation system across a -9 to 199°C range using eco-friendly CFC and HCFE-free refrigerants. The closed-loop design prevents water vapour absorption at low temperatures and oil mist release at high temperatures. An expansion vessel remains below 60°C regardless of the circulation temperature.

Suitable applications and limits

This unit suits universities, environmental protection, biochemistry, medical, chemical and scientific research fields needing continuous deep heating and fast temperature swing rates. The integrated container provides a large heat exchange area while reducing heat transfer oil volume. Buyers requiring open-bath access or a temperature range extending beyond 199°C should look at alternative equipment. The self-diagnosis and multiple overload protections support unattended operation in professional labs.

Critical specification

The operating temperature span of -9 to 199°C is the single figure that determines whether this circulator meets a specific process requirement. The sealed circulation system and expansion vessel design keep the heat transfer medium stable across the full range. Confirm that your application fits within these thermal limits before purchasing.
