How It Works

The same DG. Better combustion.

Every compression-ignition diesel engine — no matter how new or well-maintained — burns 5 to 15% of its fuel incompletely. CHFA recovers that waste.

Water In

Distilled water is fed into the on-board electrolyser. No compressed hydrogen. No storage. No PESO compliance.

HHO Generated On-Demand

The electrolyser produces oxyhydrogen (HHO) gas precisely calibrated to your engine's displacement and load.

Injected at the Air Intake

HHO enters the combustion chamber through the intake manifold — standard air path, no engine modification.

Complete Combustion

Hydrogen ignites 12× more easily than diesel and propagates flame 7× faster, reaching unburned pockets in the cylinder.

Measurably Better Output

Same diesel. Same engine. Less fuel consumed. Less PM, NOx, CO₂ at the stack. Independently certified.

Applications

Any DG. Any sector. Any vintage.

If it runs on diesel and generates power, CHFA improves it. We've deployed across sectors from pharma to defence.

🏥

Hospitals & Healthcare

24×7 standby power with cleaner exhaust for patient environments and staff working in close proximity to generators.

🏗️

Industrial Factories

Captive power DGs for manufacturing facilities — cement plants, textile mills, food processing, pharmaceuticals.

🏢

Commercial Buildings

Office complexes, data centres, shopping malls. Reduce emissions footprint and diesel bill simultaneously.

🛡️

Defence & Government

Cantonments, forward operating bases, radar & SATCOM stations, ordnance facilities, field formations.

📡

Telecom & Infrastructure

Tower sites, exchange buildings, remote infrastructure. Extend service intervals and reduce fuel logistics burden.

⚡

Prime Power Off-Grid

High-altitude posts, remote industrial sites, mining camps where grid connectivity is absent or unreliable.

NABL Evidence

Five platforms. One direction.

Every test below was conducted by NABL-accredited, MoEF-recognised laboratories. Identical load profiles before and after installation. Independent certification.
