China Refrigeration: DORIN is growing exponentially!

During the international expo in Beijing in April 2012 DORIN has gathered a great success also on the Asiatic market.

As we expected the compressors of major interest were those for CO2 applications, fields in expansion in Asia too.

At its stand DORIN has presented the new range of compressors CD and CDS respectively for transcritical and subcritical applications; the latest are ideal for cascade and booster applications.

the CD RANGE, for transcritical applications, represent the most advanced solution the market is actually having. the innovative design allows the specific fluidodynamic of internal pathways to grant the maximum results during the compression process, minimizing the thermal levels and the pressure loss this thanks to the matching of high tech solutions with a carful engineering with an eye to cost reduction.

reduction of the GWP coefficient, maximum reliability and extreme efficiency: these are the guidelines that generated the new CD RANGE, ideal solution to any type of system that keeps in its values the respect of the environment.

The CDS RANGE is a type of compressors dedicated to cascade and booster applications. the new compressors have been completely re-engineered and can be highlighted for the remarkable high values of COP. These are thank to the internal pathways fluidodynamic, a PS equal to 53 bar and a PSs equal to 40 bar.

such a high standstill pressure resistance allows to minimize the receivers of refrigerants in the case of a stop of the system and the release in the atmosphere of the refrigerant over-pressure

 

Further to these DORIN has presented, among all the other products, the far newest two stage compressors of 2S RANGE.

 

The new 2-stage compressor range is developed starting from the well appreciated H compressor range; 4 and 6 cylinder versions are available with factory assembled liquid subcooler, displacements ranging from 56 m 3 /h to 122 m 3 /h in low pressure stage and electric motor duties ranging from 15 HP to 40 HP.

Thanks to an innovative design, the compressor body works at the intermediate pressure level while a specific internal gas flow makes it possible to avoid the use of an external pipes, thus eliminating completely a leakage weak point and assuring an interesting reduction of overall dimensions.

The new compressor range features:

• liquid subcooling pipes fully assembled on the compressor

• no external interphase pipes

• compact design

• lower leakage rates

• optimised LP / HP volume ratio

• high COP levels

• low sound emissions

• extra-low pressure pulses

• capability of operation down to T_ev = -75°C (R404A)
