RenewAire GH indirect gas-fired furnaces are designed to work in tandem with our commercial energy recovery ventilators (ERVs). With two indoor models and two rootop units, the furnaces are built to match our existing product offering heat capacities that range from 50–400 MBH (input) and the ability to handle airflows from 620–11,000 CFM. Each indirect gas-fired duct furnace can be customized to address application specifics, and the system’s unique design allows air to flow freely for the lowest possible pressure drop. RenewAire furnaces can suit many site restrictions in size, configuration or orientation, and can be designed for an array of preheat capabilities in certain extreme weather conditions.
