Cleaner Air for Confined Spaces & Indoor Workshops
Running diesel engines in enclosed environments—whether it’s a mechanical workshop, an underground mine, or a fire station—poses significant health risks. Diesel Particulate Matter (DPM) is a known carcinogen and a primary cause of respiratory issues. HYDI’s Hydrogen Direct Injection (HDI) technology provides an immediate safety barrier by drastically reducing harmful emissions at the source.
The Occupational Health Advantage
Independent testing has confirmed that HYDI technology delivers massive improvements in exhaust quality, making indoor operations safer for personnel:
- Up to 80% Reduction in DPM: Virtually eliminates the fine soot particles that hang in the air of workshops and fire bays.
- 25% Reduction in Carbon Monoxide (CO): Lowers the risk of CO buildup in poorly ventilated or confined areas.
- Cleaner Engine Testing: Mechanics can perform diagnostic checks and load testing with significantly reduced exposure to noxious fumes.
Applications for Enclosed Environments
1. Mechanics & Maintenance Workshops
Maintaining modern diesel fleets requires frequent engine running for diagnostics. HYDI ensures that workshop air remains cleaner, reducing the load on expensive extraction systems and protecting the long-term health of your technicians.
2. Fire Halls & Emergency Stations
Fire crews are frequently exposed to “cold start” diesel exhaust when vehicles exit the station or during routine equipment checks. HYDI’s on-demand hydrogen ensures a more complete burn from the moment the key is turned, reducing the toxic “black puff” typically associated with heavy emergency vehicles.
3. Underground & Confined Mining
In underground mining, ventilation costs are a massive overhead. By reducing DPM by up to 80%, HYDI allows sites to maintain safer working conditions while potentially lowering the energy requirements of massive ventilation fans.
Why HYDI is Safe for Indoor Use
- No Stored Hydrogen: Unlike traditional hydrogen solutions, HYDI does not use high-pressure cylinders. It produces gas only when the engine is running, eliminating the risk of gas leaks or explosions in enclosed bays.
- Non-Chemical: The system uses only distilled water. There are no hazardous chemicals or caustic substances stored on-site.
- Automatic Shutdown: The moment the engine stops, hydrogen production ceases, ensuring zero residual gas in the workspace.

The HYDI Unit
The HYDI unit is a sophisticated but simple to use Hydrogen on demand system. It uses distilled water
and low voltage electricity from the electrical system of the vehicle or plant to produce Hydrogen.
The HYDI unit does not store Hydrogen and employs a number of safety features to prevent Hydrogen
being generated if the engine is not running.
There are no chemicals or additives used in the HYDI unit.
Just pure water.
The HYDI unit uses Bluetooth Applications to display the status on the operation of the unit on
an Android phone or tablet in real time.

Benefits
The HYDI Hydrogen on demand system supplies hydrogen gas to the engine
intake to supplement diesel fuel. The controlled addition of hydrogen into
the engine improves combustion efficiency.
This has the effect of reducing fuel consumption and to reducing carbon and
greenhouse gas exhaust emissions.
