"Our regional presence near major oil and gas and mining projects in the Northern Territory will reduce costs and lead time for delivering hydraulic and electromechanical equipment services for our customers in the region," said Pressure Dynamics' chief executive officer Stephen Harris.

Project manager Jamie Wilson will be in charge of the Darwin operation.

Pressure Dynamics said facilities and services offered by the Darwin centre would include a large clean room for hydraulic component overhauls, hydraulic component test bench, cylinder strip, assembly and test benches, hose manufacturing and testing, precision machining and fabrication services.

"Pressure Dynamics will be providing specialised equipment to be used for on-site or remote flushing, pressure testing and certification for mineral oil and water-glycol applications," the company said.

Pressure Dynamics does hydraulic systems design, installation, service and repair, and a specialist engineering and project management consultancy. Its head office is in Perth, Western Australia.
