About This Product

Some gases do not fit neatly into standard compressor categories. Biogas from anaerobic digesters contains methane, CO₂, and traces of H₂S. LPG is a liquid at moderate pressure. Ammonia is toxic and corrosive. Each of these needs a compressor built with the right materials and safety systems.

We start with the gas analysis — composition, temperature, moisture content, and any contaminants. From there, the compressor type (screw, piston, or diaphragm), materials of construction, seal types, and safety instrumentation are selected.

These are project-based machines. Lead time is typically 8–14 weeks. Each unit ships with a test certificate showing performance against the agreed specification.

Technical Advantages

Gas-Specific Material Selection

H₂S in biogas requires stainless steel internals. Ammonia requires copper-free materials. LPG requires seals rated for liquefied gas service. Materials are chosen per application.

Full Safety Instrumentation

Gas detectors, emergency shutdown valves, pressure relief to a safe vent, and flame arrestors are included where the gas properties require them.

Factory Acceptance Test

Each machine is run at the factory on the actual gas (or an equivalent test gas) before shipping. The test report documents pressure, flow, temperature, and vibration.
