Hot-Jet Billet Furnace

Unequaled thermal efficiency with tight temperature control

Granco Clark makes the most energy-efficient billet-heating furnace on the market. Our Hot-Jet Furnace delivers an average thermal efficiency of 55%—a number that other furnaces hit only at their peak.

The furnace achieves this level of efficiency through a “hot-jet” preheat section that captures and recirculates exhaust gases through high-pressure jet pipes. A pressurized entrance chamber blocks cold air from entering and keeps preheated gases in.

A PLC-based temperature control system delivers superior temperature uniformity—±10° F—with heating zones monitored by multiple thermocouple probes. Thermal efficiency and control are further enhanced with fully modulating, independent flame-impingement zones and an optional multiple-fuel firing capacity.

To further optimize your system’s operation, the Granco Clark Hot Jet Furnace can be integrated with our Log Shear or Hot Saw.
