The largest displacements available on the market

DORIN, one of the CO2 compressors technology leaders globally, has completed the qualification process of the world’s largest CO2 transcritical compressors models. During the last year several OEMs have strongly inquired for larger CO2 compressors capacities than the ones actually available: as a matter of fact the EU F-gas Regulation and the several safety drawbacks induced by the use of NH3, have led the industrial refrigeration sector to focus on CO2 as the most viable alternative also for large refrigeration duties.

After a challenging year of backbreaking testing, Dorin is now proud to welcome official orders for the following compressors models:

CD500 RANGE

 CD6 500-40B, CD6 600-40M, CD6 700-40H, 6 cylinders, nominal power from 50hp to 70hp, featuring a displacement of 39.8 m3/h @ 50Hz.

 CD6 500-45B, CD6 700-45M, CD6 800-45H, 6 cylinders, nominal power from 50hp to 80hp, featuring a displacement of 45.3 m3/n @ 50Hz.

 CD6 500-53B, CD6 800-53M, 6 cylinders, nominal power from 50hp to 80hp, featuring a displacement of 53.2 m3/h @ 50Hz.

These displacements generate the largest refrigeration capacities available nowadays: in typical medium temperature conditions (-8°C evap. temp. / 90 bar high pressure / 35°C gas cooler output. / 50Hz) an array of duties up to 125 kW (CD6 800-53M) are now available with a single compressor configuration.

In addition, all these models are characterized by and appreciated for:

• frequency drive capability

• extra smooth operation

• peculiar tribology solutions coming from the automotive industry (passengers cars engines)

• advanced oil pump lubrication

• ultra low pressure pulses and noise level

Dorin is sure, offering CD400 and CD500 compressors to OEMs, to put them now into the excellent position to have a unique opportunity to correctly address all those inquiries seeking for large capacities compressors. Dorin has then solved the actual issue of lack of alternatives to unaffordable costs for the larger refrigeration racks: as a matter of fact, given a certain duty, the aforementioned large displacements allow now for smaller amount of racks to fulfil large capacities inquiries, like it happens for:

• large warehouses

• food processing plants

• industrial applications
