Main Equipment: 
5 off GEC ALSTHOM Ruston RK 270 GS spark ignition 750 rpm (lean burn technology) low emission gas engines, fitted with 1.73 MW Leroy Somer alternators 11 kV 50hz 

Accessories: 
11Kv switch gear 22Kv switch gear 433v motor control centre, transformers 1*GEC 8-10mva
22Kv/11Kv 1 GEC 1500 kva 11kv/433v. Engine control panels with Regulateurs Europa digital 2200 governor controls, Altronic III ignition systems. 

Gas Processing: 
3 off JW 45kw gas chillers/scrubbers 1JW oil gas seperator/filtration plant c/w 3 * 225kw 2950 rpm
Durham bush gas compressors (gas compression to approximately 4.5 bar to suit engine requirements) full gas instrumentation (CH4, CO2, O2) 

Engines: 
The RK270's are proven to be very reliable with a minimum amount of down time, they would be ideal for base load applications or as stand by black start capacity for a large power station. 

Current engine hours: 
Unit 1 - 10,951 
Unit 2 - 12,941 
Unit 3 - 10,018 
Unit 4 - 14,500 
Unit 5 - 10,373 


The units have recently been converted to natural gas from LFG and all units have had major overhauls by agents MAN BW.  As part of the upgrade, all engine heads were done and out-of-spec liners were replaced.  A remote start Scada system was installed.  New turbo nozzles have been installed.  All units have had 14 hours since upgrade less than 15,000 hours total.  Units are in like new condition.

Plant is available for either deferred sale or prompt delivery depending on purchase requirements.
Comprehensive plant history records. Mechanical / electrical and civil installation drawings available. A full inventory of equipment offered will be made available to bona fida purchasers. Vendor can price reinstallation if the purchaser desires. Inspection invited.
