Principal Areas of Expertise

Each one of our compressor packages involves one or more of our four principal areas of expertise.

Process Gases

Our oil-free Duragas machines comply with API Standard 619 and can handle corrosive, flammable, radioactive and toxic gases for process applications both onshore and offshore.

Hazardous Areas

We supply packages that conform to the Equipment for Explosive Atmospheres Directive (ATEX), ANSI/NFPA 70 ‘National Electrical Code’ (NEC), CSA C22 ‘Canadian Electrical Code’ (CEC) or the IECEx System.

Special Materials

We offer a wide range of materials and paint systems which we can recommend for you according to the corrosiveness of both the process gas and the surrounding atmosphere, combined with your operating pressures and temperatures.

High Pressures

We can manufacture machines that can operate at pressures from a high vacuum to over 150 bar (2175 psi). Our single-stage Duragas machines can generate differential pressures of up to 4½ bar (65 psi). We supply multi-stage compressor packages for higher differential pressures.

Unrivalled Experience

High Specification

We routinely supply packages that meet the high specifications demanded by the petrochemical, offshore (oil and gas) and nuclear industries, such as API and ASME.

LPSR Blower

Safety

Our sealing arrangements can prevent process gas from escaping and/or contaminants from entering the process gas, according to your requirements. Our gas-tight compressors handling some of the most dangerous gases, such as hydrogen sulphide (‘sour service’) are safe and reliable.

Top-end Design and Engineering

Our qualified engineers design the blowers and packages using computer selection programs and the latest 3D CAD technology. This ensures the optimum selection of blowers and ancillary equipment, while keeping within the required footprint, and the prompt submission of correct documentation.
