POM LPG-Vapor / Air Mixers

POM BlendersAll 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 can also be used as NatGas/Air or NatGas/Nitrogen blenders (i.e. for NatGas stabilization) and come assembled on a steel skid, complete with electric/electronic controls, and all other equipment necessary for safe operation.

A PLC (Siemens S7-1200 or Allen-Bradley MicroLogix-1100) is used to monitor and control all system functions. The PLC also communicates with an Electronic Operator Interface (EOI)  with color LCD display and touch screen, displaying all system pressures in real time. And any trouble conditions that may occur are displayed in plain English, and are recorded in the Alarm History. Graphic trend recording is standard.

The PLC may also be used to "interlock" the POM system with an external vaporizer. The standard mixer control panel is designed to be installed in a non-hazardous location.

Ethernet Interface and remote access function for monitoring and control are standard.

Vapor inlet, air inlet, strainers, check valves, and regulators are "flanged". Pneumatically operated ball valves in vapor inlet and compressed air inlet are standard. The inlet valves are "fail-safe-closed" and will close automatically in the event of a power failure, or when a high-pressure condition exists.

Installations where the mixer system is separated from the water bath vaporizer (or other gas-fired vaporizer); 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. Please note that the selection is only preliminary and requires verification through AES or your distributor.

Nominal Capacity in BTU per hour (top row) and NatGas Equivalent** (m3/h; bottom row) is approximate and is given for Propane/Air mixtures 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 100-125 psig, and a pressure drop of 10% across the mixing valve at maximum flow.  The minimum vapor and air supply pressures are "Sendout Pressure + 15 psi (1bar)".

Other Blender configurations (for lower or higher delivery pressures, higher flow rates, other blending gasses, different materials, ...) are available. Please contact the factory or your area distributor for details.

 ** NatGas Equivalent: In most cases, POM blenders will be used to provide backup for a NatGas supply. Use the maximum expected NatGas flow per hour to select the correct POM model.

POM-30, POM-40, and POM-60 are available with Fisher 99 or Fisher 1098 EGR regulators for installations with sufficiently high LP-vapor supply pressure (100-125 psi) and should be used only if the LPG consists at least of 80% Propane. Higher Butane content and/or lower LP-vapor pressure require different regulator configurations. For discharge pressures above 80psi (5.6bar) POM-30, POM-40, and POM-60 are configured with a Fisher
V-Ball control valve on the air side.
