1. The pressure resistance of gas heat exchange system is 20bar, and the temperature range is – 40 ℃ ~ – 110 ℃, which can meet different temperatures;
2. Adopt environment-friendly refrigerant; The secondary subcooling technology is adopted, with rapid refrigeration and low limit temperature;
3. Brand compressors are adopted, mainly Carlisle and Emerson;
4. Adopt a full set of high-quality cold controls (Danfoss pressure controller, balance valve, expansion valve, solenoid valve, drying filter, Emerson oil separator, alco liquid sight glass, check valve, etc.);
5. Siemens S7 PLC and 7-inch touch screen are used for automatic control operation, and temperature curve display, temperature record USB flash disk and fault alarm record are provided;
6. Factory test: each unit shall be tested with load in the factory for no less than 12 hours; Factory test standard: ambient temperature 20 ℃, cooling water temperature 20 ℃, 6 bar dry compressed air.
It is used to cool the gas (without corrosion): normal temperature gases such as dry compressed air, nitrogen and argon are introduced into LQ series equipment, and the gas can reach the target low temperature and be supplied to the components or heat exchangers for demand test.
