The operational principles of Screw air compressor is that, the pair of female and male rotors, whose gears are engaged, rotates at high speed in cylinder, and make the air between the slots of rotors in volumetric periodic changes, in finally, it brings the Compound Standard compressed air to air tank. 

All the air compressors' work must go through the process, gas absorption, compression,  and Evacuation. During the long-trem operation of Screw air compressor, its nose change electrical energy into mechanical energy of rotors, the mechanical energy changes into Air potential energy. At the same time, the high-speed rotation and friction of screw, part of its mechanical energy changes into heat energy and is stored in Lubricating oil, which is about 92% of total. The traditional Heat Emanation Way is using the built-in Air cooling or water cooling system to bring the waste heat into air, which makes tremendous waste of heat energy.

In order to take full advantage of recycling of energy, the energy-saving reconstruction engineering project is gradually involved in traditional industrial production. The principle of recycle of air compressor's waste heat is that, we designed a high-performance heat exchanger for air compressor in different brands and types, uses water as a organic heat medium to dissipate the heat and absorb the heat energy, which rises the temperature of water and reduce the operational temperature accordingly. That prolongs the life of air compressor's Lubricating oil, while improves the operating efficiency of air compressor and reduce the power consumption.

The hot water recycled in final can be used in the use of Employees 'life; the heating of bathing pool, office and workshop; the canteen water and soon. Except that, it also can be used to heat the cleaning pool, supply water for boiler, paint and clean the sheet metal, refrigeration, dry work pieces and so on. It is widely used, reduce the fee of daily and industrial water's heating, and reduce the enterprise operating costs.
