Where and who do we get existing gases from ?

  • Gas Utilities - mainly natural gas

  • Industrial Gas Companies 

  • LPG

  • Acetylene

  • Hydrogen (from reformed natural gas or electrolysis of water)

Why has Hydrogen been generally the last choice for fuel gas ?

  • Low CV (Calorific Value) 

  1. Hydrogen   - 330 BTU/CF​

  2. Naturl gas  - 1000 BTU/CF

  3. Propane     - 2500 BTU/CF

  4. Acetylene   - 1300 BTU/CF

  • Perceived Safety issues, particularly with Oxygen and light back 

  • Safety issues with chemicals from existing HHO flames from water which are mixed gas systems

  • Inconvience of supply from cylinders for both hydrogen and Oxygen

  • Lack of real knowledge and experience in the supply chain compared to other fuel gases 

Types of Electrolysis with a range of commercially available Electrolysers

Mixed Gas output electrolyser

  • HHO mixed gas has one outlet connection

  • Hydrogen and Oxygen gases are mixed together immediately when they are produced

  • Alkaline type with KOH as electrolyte

  • Available for 60+ years

  • Separate gases have two separate outlet connections for Hydrogen and Oxygen

  • Acidic (PEM) with no Potassium Hydroxide (KOH) but uses built-in catalyst

  • PEM available for 10+ years

Separate Gas output electrolyser

 Safeflame uses the PEM based electrolyser in conjunction

with a specially designed post-mix torch to produce the unique 

"New Safer Flame" from water.

The Safeflame unit is different from most of the "Flame from water" that are available in the market that utilise the HHO technology. Safeflame generates Hydrogen and Oxygen gases separately using just water and electricity input. The gases are combusted in a brazing torch and offers advantages as an alternative to oxy-acetylene and oxy-propane.

Safeflame comprised 3 separate features which together represents a major advance in industry.


 

  1. The hydrogen and oxygen are generated  separately and the mixture is controlled to deliver a precise stoichiometric, oxidising or reducing flame.

  2. The length of the flame and heat flux imparted to the work piece can be adjusted instantaneously by adjusting the power input to the electrolyser stack. This provides a more flexible and user        friendly solution.

  3. The Safeflame approach eliminates the need for any stored gases, removing explosion hazards  and improving process portability.

Key Features 

  1. High temperature ~2700C, high heat flux but uniform heat transfer

  2. Quiet operation and a silent flame.

  3. Powered from 230-240V electric supply for units up to 15LPM

  4. Easy to use

  • very simple to use

  • excellent quality joints can be achieved easily

  • less likely to overheat or melt work piece

  • manoeuvrable, portable and transportable

  5. Inherently safe

  • easily seen flame

  • burner / torch remains cool to touch

  • ultra low emissions

  • no gas cylinders on site

  • no flashback, lift-off or explosion hazards

  • no danger to Fire Service personnel

  6. Suitable for brazing numerous materials

  • copper, aluminium, steel

  • HVACR, automotive & aerospace applications

  • flame stoichiometry can be adjusted

  7. Low running costs

  • very low electricity costs for typical brazing operations

  • very low water consumption rate

  • good payback period compared to oxy-acetylene

  • avoids insurance costs associated with transporting gas cylinders.

  • no need to buy oxygen

More importantly

No premix gases

No compressed gas bottles

No KOH (Potassium Hydroxide) chemicals

No alcohol like MEK or Acetone

No Flashback !!! and so NO Flashback Arrestor required
