We have grown our capability to now encompass critical gas and fluid systems plus additional defence systems.

These cover submarines, ships, military vehicles, deployable infrastructures, diving systems, recompression chambers, submarine escape and rescue, helicopters, planes, autonomous vehicles, and ground support equipment. We look after the 10-15% of the supply chain that is technically niche, locally unsupported, and often safety-critical.

The systems we manufacture and maintain include high/low-pressure gas (Oxygen, Nitrogen, Nitrox), breathing and diving air, fire suppression, AFFF, HVAC, fuel, lube oil, oily water separation, JP5 and Avcat filtration and pumping, pump integration, hydraulic systems, and aviation ground support equipment carts (liquid O2, Nitrogen generation and hydraulic).

We are also the in-country partner for Flex Force, providing counter unmanned aerial systems and weapons systems – The Drone Buster and The ASP.

If you have a difficult technical problem with a critical fluid system then we are sure to be able to solve it and support your system.

We are specialists in maintaining the following systems:

  • Hyperbaric
  • Oxygen
  • Mixed gas
  • Low Pressure (LP) & High Pressure (HP) Air
  • Freshwater
  • Fuel and lube oil
  • Pumps
  • Waste
  • Valves and actuators
  • Fire detection

  • Filtration and separation
  • Heating, ventilation and cooling (HVAC)
  • Reverse osmosis
  • Incinerators
  • Elevators and material handling
  • Windows
  • Replenishment at Sea (RAS)
