Welcome to our company, a leader in the production of high-end zero-consumption intelligent air drain devices for air compressors. Our innovative solutions enhance energy efficiency, reducing operational costs and environmental impact. By harnessing cutting-edge technology, we ensure optimal performance and reliability in your compressed air systems. Partner with us to experience the future of energy-efficient air management and elevate your operations to new heights.

  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.

  GS condensate processor developed by the company in cooperation with Nanjing University of Science and Technology is different from other oil-water separation products in the market. On the basis of separation, filtration and adsorption functions, it 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.

  Gresun's vision is to continue to do a good job of products, seriously, to create value for customers.

Cooperation with multinational companies in the compressor industry has resulted in products that serve all major brands of compressors.

We have experienced engineers, excellent sales team and perfect after-sales service team.

Passed the national high-tech enterprise certification in November 2018.Passed ISO9001, GMPC, ISO22716, BSCI, Sedex and FDA certification.
