Semi-hermetics
 
 
Officine Mario Dorin S.p.a.
produce semi-hermetic compressors that today are their core business.
OMD are able to offer a complete and diversified range of over 70 semi-hermetic compressor models with displacements from 2.9 m3/h to 400 m3/h having 0.5 to 150 nominal horse power and operating with HFC & HCFC refrigerants in response to market needs.
Main Technical Characteristics:

external discharge manifold.
valve plates and pistons designed to give maximum efficiency.
continuous research and development into high tech solutions : CPM, DPS, inverters etc.


Open Types
OMD have produced open type compressors since 1932.
Today, OMD are able to offer a complete range of compressor models from 27.2 cm3 to 1865 cm3 designed and constructed for use with HCFC and HFC refrigerants.
These compressors are built using the highest quality materials and able to work in the most severe applications.
The compressors are designed to maximise their efficiency and considerable effort has been made into noise reduction.

Condensing Units
 
In order to complete their range of products OMD offers a range of condensing units with either semi-hermetic or open compressors and with various types of condenser:

air cooled condenser.
non cleanable vertical shell and coil water cooled condensers.
cleanable shell and tube condensers for both city or sea water.
compressor receiver sets for use with remote condensers.

Transport
Open compressors of the T-transport range have been designed specifically for mobile air conditioning and refrigeration applications.
Bus air conditioning, refrigerated transport, marine and endothermic applications: these are the typical applications for these compressors.

Screw
The 'V' range of screw compressors comprises 9 models with displacements from 137 to 785 m3/hr @ 50hz. All models can be used with either HFC or HCFC refrigerants. The compressors are designed with a new 5:6 screw profile incorporating balance piston design to greatly extend bearing life. A huge range of accessories and protection devices is available ( TSD Total Safety Design ). They can be used for air conditioning, refrigeration, chiller and heat pump applications. Each compressor is subjected to rigorous quality checks and tests to ensure maximum efficiency and reliability.

Hermetic
With a large range of displacements from 5.2 to 88.4 m3/hr @ 50hz. the compressors are able to satisfy most market requirements. Leading European manufacturers have used them for many years. The compressors are ideal for use with R22 and R407C refrigerants even in the harshest operating environments such as railway or marine.
