POM LPG-Vapor / Air Mixers
     

All POM Systems are designed to be used with an existing LPG vapor source, such as a vaporizer, or as the replace­ment for less efficient or less reliable LPG-vapor/air mixing systems. They come assembled on a steel skid, complete with electric/electronic controls, and all other equipment necessary for safe operation.

A PLC (Allen-Bradley) is used to monitor and control all system functions. The PLC also communicates with a display unit (with 6‑inch color LCD and touch screen Operator Interface), indicating system pressures, temperatures (optional), and any trouble conditions that may occur. The PLC may also be used to “interlock” the POM system with an external vaporizer. The mixer control panel is designed to be installed at a remote, non-hazardous location.

Pneumatically operated full-port ball valves in vapor inlet and compressed air inlet are standard. Vapor inlet, air inlet, strainers, check valves, and regulators are “flanged”.

Installations where the mixer system is separated from the water bath vaporizer or other vaporizer with an open flame, installations with electric vaporizers, and some local codes require the option “Explosion Proof Control Components”, which also includes explosion proof transmitters and solenoid valves.

To find the right POM for your application, select the required nominal system capacity from the first column of the chart. Move to the right until you are below the system design pressure (delivered mixed gas pressure). The top row of the cell indicates the POM model number. The bottom row of the cell indicates the price for this configuration..

Nominal Capacity in BTU per hour (top row) and Nm3/h (bottom row) is approximate and is given for Propane/air mixture with 1450 BTU/cuft at delivered mixed gas pressures of 10 psig to 100 psig. Capacity for other LPG/air mixtures and/or pressures may vary. Nominal Capacity is based on vapor and compressed air inlet pressures of 125 psig and a pressure drop of 10% across the mixing valve at maximum flow.
