description
The heating module utilizes electric heating tubes to heat the circulating fluid. A built-in circulation pump, paired with external piping, transports cooling or heating media to the jacket of auxiliary equipment, facilitating indirect temperature control of materials within reactors.
For external circulation operation, connect the unit’s upper outlet pipe to the kettle body’s lower inlet. Circulating fluid will then return to the unit’s lower return port through the kettle’s upper circulation outlet, forming a closed, complete circulation loop.
features
All compressors are sourced from reputable manufacturers in France and Denmark.
Standard temperature control accuracy is ±1°C; connecting an external sensor improves precision to a temperature difference accuracy of ±0.5°C.
Overtemperature limit protection prevents uncontrolled operation by automatically cutting power if the unit exceeds its maximum operating temperature.
Compressor overheating protection activates an automatic shutdown when the compressor reaches its thermal withstand limit.
Comprehensive power supply protection is included to safeguard against electrical irregularities.
Water-cooled configurations feature protection against insufficient water flow and low water pressure.
