Requiring clean, dry compressed air for operation, the blending system is usually installed on the same concrete pad as the vaporizer, but can also be mounted in vertical orientation next to the water bath vaporizer (see drawing on left). Applicable for continuous duty or total stand-by, the units are designed for better than 50:1 turndown ratio. The PLC-based control system provides real-time information on vaporizer and blender status, first-out failure analysis, alarm history, graphic trend recording, and color LCD display with touch-screen operator interface.

The vaporizer model number (WB) designates gallons per hour propane vaporization at 0 °F liquid temperature, and the blender is sized according to millions of BTU per hour propane-air mix requirements. For detailed information, please refer to the sections for water bath vaporizers and piston operated mixers.
