Hello to all

Commissioning and start up of Howden MK2S 510 WRVTAS 51019336 with drive motor of 3800 kW so far is the biggest one in my career.

Some additional info:

Refrigerant is NH3

Suction temp in evaporator 1oC i.e. 4oC at compressor suction

Condensing temp=50oC, Condensing pressure = 21,2 kg/cm2 a

Water cooled S&T condenser ...

Motor speed 1800 rpm ....2000 rpm is max for this compressor ...

Design heat load Q= 11,8 Gcal/h


It is not easy to imagine the size of complete unit ....


Best regards, Josip
