Watlow.com.mx |Thick Film Heaters

Watlow's new thick film heaters on 300 and 400 series stainless steel are ideal for use in many applications where fast response and uniformity are essential. This high-performance heater uses thick film technology to provide maximum temperature response in a compact package. Thick film on stainless steel provides a low-profile heater that has the ability to be laser cut or machined to fit any CAD-generated, two-dimensional shape. Due to the direct surface contact, these thick film heaters ensure greater heat transfer through thermally stable and inexpensive substrates.

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.
