The heaters can be applied in areas where space is at a premium or where conventional heaters cannot be used because the voltage and wattage combination precludes using other types of resistive heaters. Because of the unique nature of thick film circuit, this heater can be designed to vary heat output across the entire surface. This feature will correct virtually any temperature uniformity problem that current designs may be generating.

Watlow's thick film heaters are manufactured to meet the requirements of NEC codes. UL^® and CSA certifications are pending.
