Indirect Fired Units – Convoluted Tube

Request a quote

The IFC series are indirect gas fired make-up air units that utilize high-efficiency stainless steel convoluted tube heat exchangers. By separating combustion air from the supply air, the unit is able to maintain excellent indoor air quality (IAQ). These units can be used in schools, offices, and institutional projects – anywhere that IAQ is paramount. The convoluted tube furnace for gas heat is one of the most cost effective indirect fired designs.
