Ambient Vaporizer
Supergap™ ambient vaporizers have become the industry standard. Supergap vaporizers use natural convection of air to vaporize liquefied gases.
Finned aluminum tubes absorb heat from the air and transfer it to the gas. A 4-inch gap between fin tips permits room for ice growth and provides more than 500 hours of continuous operation–ideal for severe climates and long duration operation.
Extended operation requires a system of switching vaporizers, available in standard aluminum construction, stainless and other alloy liners for high pressure and corrosive applications.
