Frequently asked questions
Liquimux & Gas Flux Unit
How many number of brazing torch can be connected with single tank of 5 liters?
One connection per tank to avoid backfire. Since torches in parallel or in series can cause backfire due to pressure imbalance during operation.
If any valve opens when the tank is in running condition, what is the worst situation that can happen?
There are three ball valves, one for inlet, one for outlet and one for refill of flux. Except refill valve, the other valves are open during operation. If by mistake refill valve opens, the fuel gas will escape and the torch will switch off due to starvation of fuel gas. The valve handle is designed in such way that it can be dismantled to avoid such accidents.
What is the maintenance requirement for the tank ?
Daily maintenance is not required for the tank. But, one should clean the tank once every 15 days.
If tank is not cleaned in defined cleaning frequency (i.e. 15 days), then what will be the impact ?
This tank uses volatile liquid which mixes with fuel. This liquid can condense in valves and in narrow spaces, hence to avoid clogging, cleaning the tank once every 15 days is must. This clogging can cause operational failure due to less flow of gas or chocking of pipes.
Cleaning this tank is a very simple process and takes about 30 to 45 min.
1) Dismantle tank from inlet and outlet gas tube, pour the remaining liquid through a funnel in any waste basket.
2) Attach a water hose to inlet centre valve, let water pass through entire tank and let it run through outlet valve, continue this for 15 minutes under maximum possible pressure till you get clear water coming out.
3) Disconnect the water hose and empty tank by letting the water run through funnel.
4) Now attach compressed air to inlet centre valve, let air under high pressure pass through tank for another 15 min in-between close valves for few seconds to check pressure gauge working, release pressure through both valves, that is outlet bent valve and through funnel. 5) Once you feel that tank is clean and clear of any clogging then refill container with Liquimux approx 2.5 LTR, reconnect unit and start operation.
When will the safety valve be operated ?
Actually, never open safety valve during operation, however during refill you can pull safety valve to avoid gas bubble forming in funnel. Safety valve is just a safety feature. However, one should remember that the gas that comes out is fuel gas and not air. So please follow the necessary procedures for fire safety at all times.
How we ensure safety valve is working when the tank is in running condition ?
Safety valve is set at higher pressure than operating pressure so it will not open during operation. However, these safety valves are adjustable. They can be repaired as well as can be replaced.
What is the environmental protection required to operate the tank?
A shed, possibly installed outside, metallic cage to protect against any burst in tank due to backfire and air distance of minimum 3 meter from naked flames is must.
What are the risks involved when the tank is in running condition?
Backfire is most unwanted thing that can cause harm or accident. The tank is designed in such way that in case of such accident, minimum gas is available inside the unit. The top and bottom plates are designed to take maximum impact rather than side walls. And pressure gauge and safety valve are installed to check whether the operating pressure is higher than usual. All of this is designed as a part of DFMEA.
To ensure the safety of our customers, we do not provide a flux reservoir in our tank as the reservoir can be a cause for a double impact. We also do not provide watch glass as that can also be a cause of gas leak due to faulty fitting or washers. Lastly, we have also removed openable tank concept as it hampers the safety tremendously.
