Crankcase Extractor Fan

The Crankcase extractor fan or blower is used to extract fumes from the crankcase of Ruston Diesel engines. It's primary function is to reduce pressure in the crankcase and allow the engine to be run at full speed.

We manufacture the all the versions of extractor fan found on the Ruston Diesels marine and traction engines. These include the direct drive and belt driven units. We carry a full stock of spare and replacement parts as well as producing new units.

We supply to MAN B & W Ruston as well as end users throughout the world.

Barring Gear

We manufacture Barring Gear for Mirrlees Blackstone Diesel engines. They are used primarily used on the K-engine. The unit is designed to slowly turn the engine over whilst the engine is not able to run.

They have also been used in ship yards and on board ship to turn the propeller shaft slowly, without main engine input.

As well as brand new units we offer a full range of spare and replacement parts.

Heavy Fuel Modules

Heavy Fuel Oil Modules were built by Powerwise from 1975 to 2002. They were used to prepare and treat heavy fuel oil for use by a diesel engine whilst still providing a light fuel oil supply. The principle customer for the unit was Mirrlees Blackstone of Stockport who used them on their range of diesel engines. Alex Holmes the owner of A.J. Holmes Pump Company has a great deal of experience with these units having been involved in the construction of these units at Powerwise Limited.
