Oil Coolers & Lube Oil System

We started Oil Coolers by designing & supplying ‘Oil Coolers” to Gujarat Prime Movers a division of ‘ABB’. We supplied more then 150 pairs of ‘Oil Coolers” for their steam turbines for ‘Sugar Sector”. Since then we have designed & supplied Lube Oil Coolers to ABS Bayers, ACC Ltd, Thermal Power Station and host of other industries. By now we have supplied more then 500 Oil Coolers to dozens of industry.

We have also ‘Revamped’ some of the ‘Lube Oil Systems’.

We have also designed & supplied total ‘Lube Oil Systems’ for ABB for one of their power projects. The Lube oil system consisted of oil coolers with 100% redundancy, Oil Tank, Auxiliary Oil Pump, Emergency DC Oil Pump, Vapour exhauster, Control valves, duplex filter, Piping etc. -A complete Lube Oil system to be plugged in at site.
