The refrigeration part is mechanically refrigerated by a fully enclosed compressor, composed of plate heat exchangers, expansion valves, and pressure protectors to meet the cooling requirements; the heating part is the use of electric heating tubes to heat the circulating fluid. And through the built-in circulating pump, the external circulating pipeline transports the refrigerant or the heat medium to the interlayer of the supporting equipment, and indirectly cools and heats the materials in the reactor.
During external circulation, connect the upper outlet pipeline of the product to the lower inlet pipeline of the kettle body, and the circulating fluid will return from the upper circulation port through the pipeline to the lower return port of the product to form a complete circulation space.
The heating and cooling of the explosion-proof high and low temperature circulator can be quickly switched. The medium used (high and low temperature silicone oil) is the same medium, and there is no need to change the medium after connection.
The entire liquid cycle of the high and low temperature cycle device is airtight, with an expansion vessel. The expansion vessel and the liquid cycle are insulated, and do not participate in the liquid cycle, but are only mechanically connected. No matter whether the temperature of the liquid cycle is high or low, the expansion vessel The medium in the medium is below 60°C. It can be achieved that there is no absorption of water vapor at low temperatures, and no oil mist is produced at high temperatures.
1. The temperature control accuracy is generally ±1°C, and an external sensor can be connected (the temperature difference accuracy of installing an external sensor is generally ±0.5°C).
2. It has a PLC computer module, which can be connected to a computer, can realize remote control, can realize multi-point continuous temperature control, segmented temperature control, constant temperature, and one computer can control multiple high and low temperature devices. (It is more convenient to use, and work efficiency is improved to a greater extent)
3. Equipped with USB interface, with data download function. (Data download function enables customers to download and store data related to materials that have been tested or reacted, and provide reference data for testing)
4. Maximum temperature limit to prevent the equipment from getting out of control (if the maximum temperature is exceeded, the equipment will automatically power off to prevent damage to the equipment due to excessive temperature)
5. Power supply protection (①the power supply is missing item ②the live wire is wrong item ③the voltage is too high or too low (display error code E-01)
6. Compressor overheating protection (the compressor will stop working when the compressor's withstand limit is reached, and the error code E-O2 will be displayed).
7. The water cooling has water flow and low water pressure protection (error code E-03 is displayed).
8. Sensor protection (display error code E-04).
9. All compressors are imported compressors (France, Denmark).
(1) The high and low temperature circulation device is connected to the oil pipe of the reactor, which should not exceed 4 meters (the return and return oil pipes are 2 meters each), and the connecting oil pipe exceeds 4 meters to break the glass of the reactor body.
(2) The temperature rise and fall rate of the high and low temperature cycle device is affected by the surrounding environment. (Generally, the maximum temperature range of the environment is 30℃)
(3) In areas with relatively humid environments in the south (humidity>50%), explosion-proof type should be adopted.
(4) Both the high and low temperature circulation device and the oil circuit connection of the reactor adopt "low inlet and high outlet".
