Guardian G91L

Combustion Abatement System

The Guardian G91L is a combustion abatement system designed for thermal oxidation of process gases. Effluent gases pass through a wall of active flame in the main chamber, ensuring ignition of flammable and pyrophoric process gas by-products. The extended combustion chamber is built for high hydrogen flow applications, and with no moving parts, maintenance intervals are measured in years rather than months.

Low cost of ownership
SEMI S2 compliant, CE marked

Applications

Key Features

Why Choose Guardian G91L

Active Flame Oxidation

Effluent gases pass through a wall of flame in the main chamber, guaranteeing ignition of flammable and pyrophoric process gas by-products without reliance on electrically heated elements.

High H2 Flow Capability

The extended combustion chamber is designed for high hydrogen flow applications, handling process gas capacity up to 400 slm where standard combustion chambers would be insufficient.

Low Maintenance

With no moving parts and instantaneous fuel shutoff capability, the G91L is designed for extended maintenance intervals. MTBF is measured in years, reducing the operational overhead of routine servicing.

Frequently Asked Questions

Your questions, answered

What is the difference between the Guardian G91L and the GS8?

The G91L includes a wet scrubbing stage and an extended combustion chamber designed for high hydrogen flow applications. The GS4 and GS8 use dry thermal oxidation only and are air-cooled, making them more compact. The G91L is suited for processes with higher H2 concentrations that require both combustion and wet treatment.
