208VAC Snow Melting Mats

ProMelt Mat, 3 ft. x 25 ft., 50W, 208V

Each mat holds dual heating elements on 3 inch centers on a reinforced tape grid. There’s a grounded power lead on one end for a fast, single-point electrical connection.

ProMelt Mat is a complete heating mat consisting of a series resistance heating cable and a single power lead for easy single-point connection. The heating cable is pre-formed into a mat to provide consistent spacing and quick roll-out installation on the jobsite. The heating mat length cannot be cut to fit.

Follow these recommendations when selecting ProMelt Mats:

1. Determine what voltage will be used:

120V, 208V, 240V, or 277V.

2. Determine the heat output.

The climate and amount of snowfall will dictate this choice. In general, most systems will require 50 Watts/Sq.Ft. to melt snow and ice. Some residential or light commercial systems in temperate climates, may need only 38 Watts/Sq.Ft. spacing.

3. Determine the square footage of the area to be melted.

   Do not include areas under built-ins like planters or similar obstructions. Stay 3-6” from edges of slabs and do not cross expansion joints if possible. Add up all the areas to be melted and round down the nearest mat size(s) to fill the area. Either 2’-wide or 3’-wide mats can be selected.

More than one mat can be used to melt an area(s). Combine mats in a manner not to exceed the capacity of the electrical control selected. If using our ContactorPro controls, each area should not exceed 50-amps, since these controls are built with 50-amp contactors. Therefore, we recommend dividing the area(s) into “sub-zones”, if necessary or desired, to minimize the mat amp load connected to each contactor.
