Nanjing Gresun Energy Saving Equipment Co., Ltd. is committed to providing energy-saving and environmentally friendly products and services for compressed air systems.

Our self-developed, designed and produced GM Zero Air Consumption Intelligent Drainer has won the national invention patent and a number of utility model patents, which successfully overcomes the complex and harsh drainage conditions of the compressor and saves energy while making the drainage more stable and reliable

 On the basis of separation, filtration and adsorption functions, GS Oil Separator adopts biological colony treatment technology, using special carrier to put reproducible biological colony in the condensate processor, which can more effectively reduce the COD value in the water and the difficult-to-degrade organic matter, ammonia nitrogen, total ammonia and so on.

GS heat recovery unit, using the combination of AFLF plate heat exchanger and GRF pump, the heat exchange efficiency is two times that of the ordinary heat exchanger, the special profile design makes the plate exchanger more resistant to scaling, and easy to dismantle and install the pipeline to make the maintenance more convenient.
