How it works
The TORPEDO wet-type vaporizer type WW is a hot-water vaporizer. It is indirectly heated: the heating water, preferably with flow/return temperatures of 90/70 °C, flows through the shell of the vaporizer vessel and transfers its heat to the liquefied petroleum gas (LPG) through the tube wall. The vaporizer coil is welded to the vaporizer head plate and flanged to the vaporizer vessel so that it is withdrawable.
The vaporizer is started up electrically from the control cabinet. It is ready for operation once the required vaporization temperature has been reached in the unit. Within preset limits, the solenoid valves open fully automatically under thermostat control. LPG enters the vaporizer and is converted into the vapour phase there at unchanged pressure up to the stated rated capacity.
In the event of overload, power failure or severe voltage fluctuations, the solenoid valves close. A safety temperature limiter monitors the heat transfer medium. The design and construction of the vaporizer ensure low-maintenance and fully automatic vaporizer operation, including in hazardous area Zones 1 and 2; the control cabinet is installed outside the hazardous area.

The rated capacity applies at saturation conditions to propane, butane and rDME alike. Values for the standard version; we adapt wet-type vaporizers to the order and the place of use. Special sizes up to 4,000 kg/h, also with combined heating (heating water and electric).
