Premium Polisher Biogas / RNG Skid

Explosion-rated UV-C skid that disinfects biogas and RNG in demanding, high-pressure service.

The Premium Polisher is an engineered-to-order, patent-pending UV-C skid that continuously disinfects biogas, RNG and natural gas streams — inactivating the microbes that drive fouling and microbiologically influenced corrosion (MIC) without altering methane. ASME-approved and Class 1 Div 2 explosion-rated for high-pressure, corrosive service, it runs chemical-free 24/7 with Cognituv Connect / SCADA integration and optional Prime M&V verification. A fit for RNG plants, oil & gas and district energy where hazardous-location ratings and continuous microbial control matter.

How it works

The Premium Polisher passes biogas and RNG through UV-C treatment chambers where 253.7 nm germicidal light inactivates microbes that drive fouling and microbiologically influenced corrosion — without altering methane — in an ASME, Class 1 Div 2 explosion-rated skid.
