QM Packaged Propane-Air Back-Up System

The Algas-SDI QM natural gas replacement system is a combination gas fired waterbath LPG vaporizer and atmospheric venturi LPG/air mixer. All QM models feature an Eclipse Combustion ThermAir forced draft burner and Algas-SDI optimized venturi mixers. Operation of these units has been proven in -40 F climates. PLC controls with an easy to use operator interface are provided in a temperature controlled enclosure to ensure long-term reliable operation.

A “Smart-Start” cold start feature automatically senses and controls the inlet propane pressure to make sure only vapor is fed to the burner until the bath is warm enough for full vaporization. When the bath has reached operating temperature an output is switched by the PLC that turns on the LPG pump (STABILAIRE). A maintenance program tracks the hours used, venturi cycles, and burner cycles to allow the user to schedule service accordingly. Flow totalization is also provided for convenience.
