Advantages of Hot Water Bath type LPG vaporizer

NO NEED OF ELECTRICITY

The greatest advantage of Hot Water Circulating Water Bath type LPG vaporizer is that it doesn’t require electricity.
It’s the ideal solution for ensuring stable gas supply in locations where electricity is not available.
Its vaporization stability and safety feature are also advantages.
Hot Water circulation type vaporizer uses 75-85℃ hot water circulated from the water boiler as the heat medium for vaporization.
This hot water indirectly heats the liquid LPG running through the heat exchanger tube.
As the heat source is hot water with a gradual temperature change, the vaporization of liquid LPG is stable.
And even if there is a problem with the heat source, the vaporization ability can be exerted while the water is warm.

• Water temperature to be controlled between 75-85℃ by the water boiler
• Spiral shape heat exchanger tube for smooth and stable vaporization
• Patented technology of Float Valve + Magnet system to prevent liquid carry over

As the Liquid LPG (Propane) is heated indirectly by the hot water, it is safer than Direct Fire type vaporizers.
And since no electrical parts are used, no electrical sparks are generated.
In some countries with specific gas regulations, Hot Water Bath type can be installed much closer to the tank / cylinders.
And its operation is noiseless.

Vaporization mechanism of KAGLA Hot Water Circulation type vaporizers

Function of Float Valve system (**1) – KAGLA patented technology

FLOAT VALVE is a safety function to prevent LPG liquid carryover to the downstream.

1) Float Valve shut off mechanism

Float Valve is a safety mechanism to prevent Liquid Carryover to the downstream.
When the gas consumption exceeds the vaporization capacity of the vaporizer, vaporization of LPG liquid may not catch up with gas consumption by the combustion equipment.
In this case, the non-vaporized liquid LPG will come into the gas chamber.
Then KAGLA Float Valve inside the gas chamber will be lifted upwards by the liquid and shut off the valve tightly with magnet connection.
Due to the phenomenon that the liquid pushes up the float, the gas chamber outlet is closed by the valve at the top of the float and prevent the LPG liquid from flowing to the downstream. Since it does not require external power sources such as electricity or pilot air, it is a system that operates reliably under all circumstances.
It also works in cases such as when the boiler fail to circulate hot water as required.

• It is a normal operation state where the hot water temperature is appropriate and heat exchange with the LPG liquid is properly performed. Since there is only LPG vapor in the gas chamber, the float is seated at the bottom position and thus the float valve is open.
• When the temperature of hot water drops and heat exchange does not occur properly, unvaporized LPG liquid flows into the chamber. Then the liquid accumulated in the chamber pushes the float valve upwards.
• If gas consumption continues in this state, the float valve will be forcibly closed by the powerful magnet placed on the top of the float valve.
