From the design to technology




Since its birth in 1991 RefComp brand has been distinguishing itself for its innovative ability initially for the piston, then for the screw compressors. RefComp was the first Italian company to design, develope and produce a complete range of twin-screw compressors with an incorporated oil separator for specific application in the AC and industrial process fields.

From the first compressors range called “S”, other series have followed such as the “W”models specific for the medium-low temperature in the industrial refrigeration and the “ES” series. This latter one was the first screw compressors range in the world expressly designed for refrigerant R134a application, still today considered as a “staus of the art” compressor.
To further prove its technological excellence, RefComp was the first brand in the world showing in 2008 a screw compressor with an incorporated inverter, cooled by refrigerant.




DUNAN, founden in 1987, is a chinese multinational corporation which works with 6 different product’s divisions and employs about 19.000 employees in China and around the World. It is included in the first 500 chinese private companies.

Inside DUNAN group, DUNAN Environmental is leader at the global level in the valves production for refrigerant applications both in the commercial and also industrial branch. During the years DUNAN’ s abilities have been grown with the production of tube & fine heat exchangers. Recently a new division has been created for the production of aluminium microchannel heat exchangers. Actually this is  the most advanced technology available in the heat transfer applications in AC and refrigeration. Today DUNAN has several production plants located in China, Thailand and USA.




RefPower also proposes a differentiated and complete range of cooling pads characterized by high efficiency and resilience. They are used in many different refrigerant applications when an initial adiabatic effect for air cooling and/or humidification going through a heat exchanger is required.

The different available pads let the users easily identify the best solution considering the needed air humidifying grade and the linked accepted pressure drops. The pads are supplied with standard or customised dimensions, basing on the customer’s necessities. Furthermore, systems of water’s conducting, distribution and renewal are available.
