Auto Change-Over Regulators
The MEGR-253 Series Automatic Changeover regulators automatically redirect LP gas vapor ow from an empty service cylinder to a reserve cylinder, without interruption of service. It features an easy to read green indicator which changes to red when the service cylinder needs to be refilled. The MEGR-253 regulator meets UL, RVIA and NFPA requirements.
- Maximum inlet pressure: 250 psi
- Inlet connection: 1/4 in. female inverted flare 2
- Outlet connection: 3/8 in. FNPT 1
- Primary cylinder BTU/hour: 225,000
- Reserve cylinder BTU/hour: 150,000
Automatically redirect LP gas vapor ow from an empty service cylinder to a reserve cylinder, without interruption of service. It features an easy to read green indicator which changes to red when the service cylinder needs to be refilled. As a 2-stage high-pressure regulator, the MEGR-253H reduces container pressure to approximately 10 to 15 psig and then the second stage completes the process by reducing inlet pressure down to 11 in. of water column outlet pressure.
- Type: 2 stage
- Max inlet pressure: 250 psi
- Inlet connection: 1/4 in. female inverted flare (2)
- Outlet connection: 3/8 in. FNPT (1)
Combines the first and second stage regulator into one unit converting full tank pressure to 11 WC. MEC Excela-FloTM Automatic Changeover regulators prevent gas outages by switching supply cylinders over to the reserve cylinder automatically when the primary cylinder is near empty. When the primary cylinder is depleted causing the changeover to occur a red indicator will appear signifying the reserve cylinder in now in use and the primary cylinder can be refilled without loss of service.
- Type: full size high pressure automatic changeover 2-stage
- Maximum inlet pressure: 250 psi
- Orifice size: 0.219 in.
- Primary cylinder capacity in BTU/H LPG: 650,000 / auxiliary cylinder: 570,000
The MEGR-253L is specifically intended for application with low BTU demands but still require 2-stage regulation. The Model MEGR-253L is ideally suited for RV, manufactured homes, cabins or other applications with a single appliance or low BTU multiple appliance applications while still permitting maximum range of output pressure adjustment. The MEGR-253L regulator meets UL, RVIA and NFPA requirements.
