Petro Chemical Offshore Supplies Ltd was originally formed in 1979 to supply mechanical equipment to the Oil and Gas industry.

The principal business at the time was design and manufacture of rig based winch, compressor & pump packages.

Ingersoll Rand initially formed the backbone of our company's products, and over the years PCOS has evolved to help provide an ever increasing range of oilfield equipment to support many aspects of the compressed air market.

Please take some time to browse through some of the products we distribute using the revolving navigation at the top of the page. If the product you require is not listed please let us know and we will endeavour to source the product you require.

The Ingersoll Rand brand has been in the forefront of compressor technology, design, and manufacturing since the early 1900's. From piston to vane, and into the current era of screws, Ingersoll Rand has maintained its place as "World Leader".

In 2007, Ingersoll Rand Portable Power became part of the Doosan family of companies, under the new name of Doosan Infracore Portable Power. The product line continues to enhance user productivity and offer best in class reliability.

With their comprehensive range of air compressors, lighting systems, and generators and rugged and reliable light compaction and pneumatic tools, Doosan have a solution to fit your needs, plus an experienced global dealer network to stand beside you every step of the way.

Doosan Infracore Portable Power - 135 years of providing excellence.

We are agents for Ingersoll-Rand reciprocating compressors and also supply compressors from other manufacturers as complete machines or spare parts for servicing and repair.

We can supply recommended spares kits for quarterly and half yearly services or individual parts for breakdown and repairs.

With over 30 years experience of the compressed air industry we can advise our customers on installation design and improve expected quality of air using filters, lubricators and compressed air dryers, as well as supplying air receivers, level switches and drain traps.

Our stockholding of spares covers a range of valves, pistons, connecting rods, cylinders, gasket sets, pressure switches, air governors, vee belt drives and pulleys, electric motors and compressor oil and lubricant.

PCOS are able to offer most standard electric motors from 0.11 Kw to 200 Kw from a range of manufacturers including Fenner, WEG, Siemens and Brook Crompton.

Special motors including Explosion Proof and High Voltage can also be supplied.

We are able to offer special feature motors to your specification including special "one off" replacement manufacture for old motors where the replacement has to be identical to original motor.

As well as sourcing new electric motors we are also able to repair & rewind rotating equipment including AC / DC motors, alternators and motor generator sets.

Our special purpose division is capable of manufacturing skids to customer requirements.

Where manufacturers are not able to fulfil exact requirements then we are prepared to design, engineer and produce skid mounted units to fit your specifications. PCOS have supplied instrument air compressor skids , pump lubrication systems, oil free and explosion proof compressor skids, high pressure compressed air systems for start up and breathing air applications.

Our engineering department will liaise with you on the type of equipment required, sized to fit your workshop and volumetric output and pressure. Sets of drawings will be issued for you to approve and complete sets of manuals will be supplied on completion.

Final inspection and staged inspection can be accommodated and final installation and commissioning on sight can be included.

We will also suggest spare parts either for start up or for 2 years which will be part of our completion manual.
