FREEZE - SAFE

FREEZE-SAFE Classified Location Flexible Heated Mats for Low Temperature Applications

Based on its patented THERMOPOLYMER® technology, Watlow has embedded a safe, low watt density heating element into a thermoplastic elastomer mat.

Features and Benefits

THERMOPOLYMER heated mats are free from seams and joints

Watlow’s FREEZE-SAFE hazardous location Thermo Plastic Elastomer (TPE) heated mats are custom designed for your application in sizes or shapes up to 20 x 25 inch (508 x 635 mm). Consult the factory for larger sizes.

FREEZE-SAFE heated mats are designed for use in classified locations. (Class 1, Div. II, Group A, B, C, D).

Class 1, Div. II are locations where explosive vapor conditions could exist in the event of abnormal operation, an accident, or component failure. Flammable gases and liquid groups (such as acetylene, hydrogen, ethylene, gasoline and propane) are included in this classification. Refer to articles 500 through 505 of the National Electric Code for more information on the use of electrical devices in classified locations.

The hazardous location heated mat can be used in a variety of ways. These flexible panels provide spot supplemental heat-tracing while simplifying installation and maintenance. Nearly any curved 3-D shape can be wrapped with a Watlow FREEZE-SAFE flexible heated mat. Multiple heaters can be used to cover the entire surface.
