Details

Detects leaks everytime, simply and quickly

The Gasfuse is a must have essential for every gas appliance and acts like an electrical circuit breaker for your gas bottle. Fits easily in seconds!

The Gasfuse gas safety gauge is a clever device that allows peace of mind when using your LPG (Bottled Gas) Cyclinder. It functions as a fuse which detects and visually signals gas leaks, and automatically shuts off any major leaks. As well as maximising user safety this reduces environmentally damaging hydrocarbon emissions. Gasfuse screws directly into an LPG cylinder and the hose and regulator and can be easily retrofitted.

Cutting edge gas safety technology

Gasfuse is patented and trademarked in over 43 countries. Eleven years of research and development have placed it at the cutting edge of gas safety technology. It utilises internal flow dynamics to power a mechanical shut-off apparatus, making it independent from external power – a major safety advantage.

The industry accepts that over 70% of gas systems leak to some degree. LP Gas is used mainly indoors, in domestic situations. Since it is stored under pressure and is virtually odourless and highly flammable, undetected leaks can and regularly do cause serious accidents. Numerous products have claimed to solve this problem but failed to deliver. Gasfuse is the only product which genuinely delivers an affordable, reliable, simple and quick way to check if a system is leak-free before ignition, and to protect against significant leaks.

Gasfuse is fully developed to international standards, having been tested and approved for sale by the most stringent and internationally recognised technical safety organisations. It was awarded the Asian Nations Trophy for Safety to Mankind in Geneva in 1988.

In Australia Gasfuse is marketed through exacting, highly reputable retailers, with solid sales success. Internationally it meets a vital safety need, and is affordable to 90% of 717 million LP Gas consumers worldwide. Its potential market – particularly in the Indian subcontinent, the Middle East, Asia, USA, Europe, South America and Russia – is therefore vast, and in third world countries is growing exponentially.

How to use the GasFuse:

How to connect

Gasfuse screws directly into an LPG cylinder. The hose and regulator from your appliance then screws into Gasfuse.

 

For Major Leaks

If there is a major hose rupture, for example from a fire at the appliance or the hose detaching, you don’t need to do anything – Gasfuse will simply shut off whether you’re there or not. When the problem is fixed, just pump the gauge 3-4 times, and the gas will start flowing again. If the problem hasn’t been fixed properly and the hose ruptures again, Gasfuse will shutoff once more.

 

For Leak Detection

You can determine if there are any leaks in any gas connection that has a Gasfuse attached. Turn the appliance off, and the LPG cylinder on. Pump the gauge 3-4 times to let the gas flow, then turn the LPG cylinder off. Now watch the gauge for a few minutes – if there is any leak, the needle on the gauge will move.

 

As a Low Gas Indicator

Gasfuse tells you when you need to change cylinders or get a refill. Turn your appliance on and run it for a few minutes. The gauge is clearly marked and colour coded. When the needle falls into the red zone marked refill, you know you’ll be needing more gas soon.

How it works:

 

The Flow of Gas Through Gasfuse

The diagram above shows in simplified form the path of gas through Gasfuse. Here’s the sequence of normal gas flow.

  1. Gas enters the Gasfuse directly from the cylinder
  2. Gas is channeled into a chamber, where it passes the shutoff element.
  3. Gas is then channeled up out of the chamber and past the gauge pin.
  4. Gas then exits

The various uses of Gasfuse all follow from this sequence. Importantly, the gauge pin is directly attached to the gauge, and acts as a pressure detector, which causes the gauge to show changes in gas pressure via movement in the needle.

How Gasfuse Stops Major Leaks

The shutoff mechanism works on the Bernouilli effect. A sudden increase in gas flow (for example from the hose rupturing) changes the pressure around the shut off element, lifting it up and causing it to plug the exit to the chamber and stop the flow of gas completely.
The shutoff element will stay in this position until you push down on the gauge. The gauge pin then pushes the shutoff element back down into the chamber, so resetting the Gasfuse ready for normal operation.

How Gasfuse Detects Small Leaks

By turning the cylinder on and the appliance off, you allow gas to fill the Gasfuse, gas hose and all gas pipes and manifolds, all the way up to the appliance.
When you turn the gas cylinder off, the gas should stay in the Gasfuse, hose and inside the appliance. If there is any leak, the pressure should drop because gas is escaping but not being replenished (because the cylinder is off). The drop in pressure will be detected by the gauge pin, causing the needle to move downwards.

How Gasfuse Tells You That You’re Low On Gas

The gauge detects pressure through the gauge pin. When gas in the cylinder is low, the pressure drops and the needle falls towards the red section of the gauge.
