Unlike direct-fired heaters, Flex-Temp’s Indy Heat provides clean air, free from moisture and contaminated fumes. Indirect-fired heat disburses warm air over large interiors, enclosed structures or vast surface areas. Side panel outlets offer access to duct connections. Work area temps go up quickly and allow projects to move forward. It’s mobility and 1,000,000 BTU heating power takes the cold out of winter weather projects.
