1. The situation of oil free compressors heat recovery

In the operation of oil free Screw compressor, it will produces high grade energy，has a large space for recycling. More and more people attach importance to oil free compressors transformation, but the process of it always has two widespread problems. 

（1）large cost, low recover efficiency, short woring life, long pay-back periods.

（2）large ground occupation area, need large costs, low recovery efficiency, short service life, installation is limited to space to some extent.

Through long term practice, the HYNOVs RD team invents a new heat recovery system of oil free compressor, and gets State Patented Invention. The birth of this system, opens a new era in heat recovery industry of oil free compressor.

2. System Characteristics

（1）  place vertically, avoid the scaling on surface of popes.     

（2）pure counter flow design of heat exchange, the efficiency is higher than before.

（3）no retention domain, no leakage, not easy to scale.

（4）avoid manufacturing requirements of the pressure vessel, less solid fouling

（5）the air walk through the interlayer, the pressure loss is less than theplate-type.

（6）the scales sedimentation uses the detachable design, the cleaning and maintenance are easy.

（7）the exit of sedimentation and drain can be setup easily, and cleaned online.

（8）all in **6l stainless steel, have corrosion resistance to CI-, the design working life is over *0 years.

（9）the heat exchanger uses module design and parallel installation, easy to maintain.

（*0）heat directly to supply water, the pipes and pump are small, easy control, low failure rate.
