Saint-Gobain Advanced Ceramics/ Igniter Products (Norton)
Booth Number 4329

Saint-Gobain Igniter Products will exhibit its entire line of CRYSTAR¨, MINI, and MIM¨ hot surface igniter products at the Expo. Among the new product offerings are the "SLOTLESS" MINI-IGNITER, the "jump-start" technology, and the "low aging" MINI-IGNITER products.

The "slotless" igniter products are the latest generation of MINI-IGNITERS. These igniters are designed to provide the industry with hot surface igniters of higher strength and durability. As with other Saint-Gobain igniters, the "slotless" products work reliably across the entire range of operating voltage (-15 percent to +10 percent of nominal voltage), without the need for special electronics or controls.

The "jump start" technology is an electronic means by which MINI-IGNITERS can be provided that reach ignition temperature in less than 3 sec across the entire range of supplied voltage (nominal -15 percent to + 10 percent). This feature is said to effectively provide hot surface igniters that operate as rapidly as spark ignition. Furthermore, the technology can be adapted to provide for a controlled igniter temperature across the entire range of supply voltage, thus improving ignition performance and igniter life. This technology reportedly is easily integrated into existing HVAC controls.

The "low aging" MINI-IGNITER is comprised of a new proprietary ceramic/intermetallic material system. When operated at temperatures of 1,300º to 1,350ºC, the igniters are said to exhibit extremely low levels of both current and temperature "aging." This provides for the potential of life of the appliance level service life.
