The glass face heater is used when there is concern of material falling onto the face of the heater. The glass face allows for easy clean up, without damage to the heater or heating element. Common applications are the bottom oven in a thermoforming machine or the bottom heater in a wave solder oven. Durability is defined by a typical life expectancy of 25,000 hours. Because the heater design does not depend on an external reflector, the heater maintains that efficiency over time.
All heaters provide uniform coverage with the convenience of a cleanable surface.
The face can be either hard-coated aluminum or porcelanized steel. The remaining construction is exactly the same as the G-Series heaters. The heater face can be provided with air holes for forced airflow as in the FBA construction. The metal face is used when there is concern of material falling onto the heater face. The metal face is more durable than the glass face.
