The real innovation of Dorin was born in 1999, the year in which new technologies have been developed such as the application of frequency modulation and the use of CO2 as a refrigerant.
Since 2004 OMD is the main reference manufacturer of CO2 compressors for transcritical application, recognized throughout the world in every commercial sector. Soon Dorin became a reference point for the use of CO2 in subcritical phase too.
During the same period have been designed and manufactured compressors Series HI, specially designed for the electronic control of frequency, products which have now been successful in those markets concerned with implementing a strict policy of energy saving.
In 2008, the birth of the compressors H4, H5, H6 and H7 have completed the entire Series H.
