There are two categories of integrated heating and cooling machine series, namely air-cooled box type and water-cooled box type; the heat exchange medium can achieve heating and cooling in different ranges of +300℃ to -120℃, and can also achieve constant temperature in the interval of +300℃ to -120℃, heating capacity and cooling capacity are available from 1KW to 600KW. The heat exchange medium matches different flow rates according to different working conditions and cooling capacity output. The product is fully produced in the factory. After testing various indicators, filled with refrigerant, and then through water and electricity power to start commissioning, to ensure that all parameters are qualified before leaving the factory.
