DESCRIPTION

Heating part is the use of electric heating tubes to heat the circulating fluid. And through the built-in circulating pump and the external circulating pipeline, the refrigerant or heat medium is transported to the interlayer of the supporting equipment, which indirectly cools and heats the materials in the reactor.

During external circulation, connect the upper outlet pipe of the product to the lower inlet pipe of the kettle body, and the circulating fluid will return to the lower return port of the product through the pipe from the upper circulation port to form a complete circulation space.

FEATURES

1. The temperature accuracy is generally ±1°C, and an external sensor can be connected (the temperature difference accuracy is generally ±0.5°C).

2. The maximum temperature limit to prevent the equipment from losing control [If the maximum temperature of the equipment is exceeded, the equipment will automatically power off.

3. Has power supply protection.

4. Compressor overheating protection, the compressor will stop working when the compressor withstand limit is reached.

5. Water cooling has water flow and low water pressure protection.

6. All compressors are imported compressors (France, Denmark).
