Thick Film Heaters
Watlow layers thick film resistor and dielectric materials on quartz and stainless steel to produce high performance industrial heaters. The thick film heaters provide very fast temperature response and uniformity on a low-profile heater. Thick film heaters are ideal for applications where space is limited, where conventional heaters can't be used, when heat output needs vary across the surface, or in ultra-clean or aggressive chemical applications.
