Many aluminium foundries and casthouses around the world rely on Pyrotek’s compact and portable Zen heater units to preheat refractory parts and other operational components. These units are safe and useful for any high-temperature application where preheating is necessary, up to 1,500º Fahrenheit (816º Celsius). They allow operators to avoid contacting the surface of their materials with direct flame.
Zen units provide preheating for troughing systems, caster tips, spouts, pins, tabletops, tundishes (casting tubs), and ceramic foam filter cartridges, among many other components.
Successful Customer Applications
- A Pyrotek customer purchased a Zen preheater to bake out its billet casting tables after regular maintenance. The customer reported successful use. Seven years and counting.
- A customer used the Zen to preheat caster tips successfully. Three years and counting.
- Customer preheated ceramic foam filter (CFF) cartridges successfully. Two years and counting.
- Customer opted for the Zen to preheat distribution troughs successfully. Five years and counting.
The Zen system uses electrical heat with forced air pressure for precise distribution of heating. The electrical control system varies depending on the temperature control requirements of operators. The Zen system can be wall-mounted or be cart- or dolly-mounted for portability.
“The Zen offers electrically heated air, rather than combustion,” says Will Hadley, Program Manager and one of Pyrotek’s product experts for the Zen units. “This offers the benefit of eliminating flame impingement on the refractory or other preheated part.”
The Zen preheater helps plant maintenance teams avoid damaging their refractory and filter parts. The damage from flames can cause premature failure of these parts.
“The Zen delivers much better temperature control and regulation than combustion systems,” says Mike Tomassi, Chief Engineer at Pyrotek's Cortland, New York, USA, facility.
“There is also no opportunity for gas leaks or other required safety regulations that often come with using combustion systems,” Tomassi says.
Additionally, the Zen uses standard welding outlets for power, so no additional utilities are required.
“The Zen is typically more energy efficient,” Tomassi says. “Pyrotek offers units that operate at different voltages to serve customers globally.”
Zen preheating systems are available in Premium, Standard, and Economy options. Pyrotek engineers can customize the units to fit any customer application.
