Minimizing operating costs & ensuring environmental compliance are business-critical in the Water and Wastewater sector. That’s why utilities have been using our oil-free compressors since the 1960s for compression and recirculation of saturated, corrosive sludge gas (biogas) in anaerobic digesters and aerobic treatment plants.

Our High-speed turbo compressors, which utilise air bearing technology and operate at speeds up to 100,000 rpm, have found widespread usage in the water industry as they deliver both massive energy savings of up to 35% of site operating power and virtually maintenance-free operation.

Typically used for fine bubble aeration, each installation ensures utilities can meet effluent consents and environmental permits required by the EA.

Today we are a major player in this field, and our ‘Hook & Claw’ dry running (oil-free) gas compressor is recognised as the market leader by many engineers in the sector.
