The GDXH series uses a circulating pump and a closed heat-transfer system to provide heating and cooling for external equipment. The heat-transfer medium passes through the heating unit and refrigeration heat exchanger to achieve the required circulation temperature.
The closed pipeline design and heat exchanger support efficient heat transfer while reducing the amount of heat-transfer fluid required. The system is suitable for fine chemical processes, pharmaceutical applications, and new-material synthesis involving reactors and jacketed vessels.
The GDXH series includes multiple refrigeration temperature variants to accommodate different process requirements.
