Product Description

Product Description

Watlow’s 430 stainless steel thick film conduction heaters are ideal for use in many applications where fast response and uniformity are essential. A clamp-on thick film heater provides the best possible combination of heat transfer, thermal efficiency and temperature uniformity.

These high performance film heaters use thick film technology to provide maximum temperature response in a low profile package. This film heater technology can be applied in areas where space is at a premium or where conventional heaters cannot be used because of limited voltage and wattage combinations.

Thick film conduction heaters provide a low-profile heater in a variety of shapes. These shapes include two-dimensional circular and rectangular forms. Due to the direct surface contact, a thick film heater ensures efficient heat transfer through thermally stable substrates and precise resistance trace patterns.
