Midco International Inc. | Products

The MPG series of gas burners have been developed with modular construction to make them adaptable to many applications. The MPG series is available with the blower on top as standard and also available for the tighter applications with the blower on the bottom. The burners have been UL and UL-C approved. We can provide optional valve trains and controls to meet ASME CSD-1, Factory Mutual, NFPA and GAP (formerly IRI) specifications.

At the heart of the MPG burner efficiency is the innovative burner gas manifold and its stainless steel retention plate, precision engineered to thoroughly mix gas fuel and combustion air for increased combustion efficiency. With less excess oxygen required for combustion, combustion efficiencies can be increased.

The MPG series comes standard with a 120V electronic microprocessor flame safeguard and flame rod sensing or is available with optional UV sensing.

The MPG series of burners can be applied to numerous applications. The standard product is completely factory assembled and fire tested. The standard burner style of firing is on-off with slow opening diaphragm gas valve and fixed air shutter. We have available Hi-Lo-Off firing or 3-1 and 10-1 turndown modulation capabilities. For OEM models, we offer numerous options as well as unassembled valve trains and welded flanges to fulfill many application requirements.

The Unipower MPG GB burners are provided with a 24 volt electronic intermittent pilot ignition module with self diagnostic features employing the flame rectification of flame detection. A 120 volt ignition transformer insuring reliable pilot ignition is standard.
