Gasmac Incorporated of Ontario, Canada manufactures painting systems used in industrial plants, and the company specifies Munters air-to-air heat exchangers as a regular feature on its lines.
In a recent application demonstrating the effectiveness of the heat exchangers, Gasmac built and installed a new paint line for a steel processing plant in Slovakia to coat one side of steel sheeting with a decorative finish. The coating requires curing in an oven, and because the process uses solvent-based paint, the plant needed to incinerate fumes emanating during curing.
Gasmac devised a system that uses a natural-gas-powered burner both to heat the oven and incinerate fumes coming out of it. Munters Thermo-Z™ heat exchanger captures exhaust heat at 1400°F to preheat ambient air to 1200°F at the inlet for combustion.
Using this arrangement allowed Gasmac to specify a smaller burner than would otherwise have been required, reducing fuel consumption by 85%. The system also allows more control of the oven temperature and, most importantly, saves fuel for the steel company.
About Thermo-Z
The Thermo-Z™ all-welded heat exchanger, offers modular design with heave gauge, welded-plate construction, and guaranteed leakage rates less than 0.01% factory tested. Thermo-Z™ offers integral thermal expansion compensation and an insulated shell with an all-welded outer casing for increased performance. Both crossflow and counterflow configurations are available. Variable plate spacing is utilized to optimize performance, pressure drop, and service requirements, providing the most efficient and maintenance free heat recovery equipment available.
Welded construction eliminates the possibility of premature failure and increased leakage caused by particulate build-up in the compression seals of a non-welded unit.
