The most commonly used, vapor phase, organic heat transfer fluids are Dowtherm "A" from Dow chemical and Therminol "VP1" from Monsanto. Both of these fluids allow process heating up to 750F at a relatively low operating pressure. For example, a steam system at 750F would have an operating pressure well over 3200 psig, while Dowtherm A and VP1 produce a vapor pressure of only 138 psig. The vaporizer consists of an ASME pressure vessel, a heat source of open coil heaters contained in 3" sch. 40 pipe wells, vessel mounted safety devices and an intergral control center.
Electrically operated organic fluid vaporizers are usually custom designed, but are also available as a "Pre-Engineered" packaged system, prewired, prepiped, insulated, pressure tested, and ready for installation.
Long life, utilizes low watt density open coil heating elements
Removable elements, no need to drain system for replacement
Provides high process temperatures at relatively low pressures
Less fluid required compared to fluid system
Better temperature uniforminty compared to fluid system
Gravity return system, no pumping required
