In some or most educational and medical establishments compressed bottle gases are not allowed onto their premises.

This could lead to lost business in a competitive environment.

In some commercial establishments, Refrigeration or Air Conditioning engineers are not allowed to bring compressed bottle gases onto their premises. e.g. hospital, Supermarket

What is Safeflame ?

Safeflame is a package of specially designed torches linked to PEM stack electrolyser with separate streams of Hydrogen and Oxygen. This is not to be confused with flame from electrolyser which produces mixed gas and use corrosive chemicals and alcohol. This flame is very soft, neutral and concentrated giving more control over the brazing process.

The gas pressure in the electrolyser is very low (< 0.5 bar) which is below the safety regulation for high pressure vessels.

There is no Hydrogen and oxygen gas storage because the machine produces the hydrogen and oxygen gases from the electrolysis of water on demand.

Brazing with Safeflame does not require the operator to wear special glasses. In addition, the fumes are reduced by about 60-70%. The by-product of the combustion of Hydrogen and oxygen is water.

Safeflame addresses the safety issues in the huge global market of brazing and other flame applications.

The flame brazing process is used across industries as diverse as refrigeration, air conditioning, ship building, aviation, rail stock, car repairs, jewellery, dental technology, acrylic polishing etc. There are hundreds of thousands people involved in those industries.

Currently brazing and many flame processes use highly flammable bottled gases such as acetylene and propane contained in high pressurised cylinders. Safeflame products have 3 unique features which brings major benefits and safety improvements to the sector, decreasing the risk of accidents and the cost of insuring operations, buildings, transportation vehicles etc.


Each year in the EU there are hundreds of serious incidents involving bottle gases such as acetylene, propane and oxygen. These gases are routinely used in well over 100,000 individual applications using fuel gas and oxygen flames by manual torches for fabrications by welding, cutting and brazing of items such as refrigeration and air conditioning plants.

In the UK alone the Fire and Rescue attend about 100 incidents each year in which acetylene cylinders have been involved in a fire. These cylinders known to have failed catastrophically, generally split axially and fragments into several pieces. These fragments have been known to travel distances in excess of 200 metres under rocket propulsion of the burning gas which they contained. In addition to the fire and explosion hazards, the shrapnel can penetrate masonary, metal containers and of course human body.

Because of these obvious safety concerns, the cost of insuring operators and vehicles transporting bottled gases can be prohibitvely high. Safeflame aims to bring major benefits to safety and cost within this sector.

It is important to note that no hydrogen or oxygen gases are stored in the Safeflame unit as they are only generated on-demand. So, in the event of fire there is no risk of gas explosion as a result of the Safeflame unit. 

Safeflame units have separate pressure gauges for Hydrogen and Oxygen. The system is designed in such a way that if the pressure exceeds 0.5 Bar, the system will shut down. If either of the gas pipes are clamped or restricted the pressure will build up and trigger a system shutdown as a safety feature.

The water tank have a high and a low Led to prevent water running out or over filling the water reservoir tank. Different size unit will have different size reservior tank.


Safeflame unit have the facility to turn up or down the output of gases electronically and so do not have manual valves and free from changing nozzle size to match specific gases output.


Unique to Safeflame there is a facility to "boost" the output of hydrogen and gases by up to 50% more than the standard output. In addition there is a facility to bleed off some oxygen from the electrolysis process thus can provide a less than stiochiometric gas mixture to reduce oxidation in the burning process.

There is a "purge" facility to allow remaining gases in the gas pipes to escape after the system is shutdown manually as a safety precaution.
