ProMelt Mats

ProMelt Mat Installation ProMelt Mats melt snow and install quickly. All you need for a typical small-to-medium size project is a control and mat.

ProMelt heating elements are surrounded with high-temperature ETFE insulation and the engineered polyurethane outer jacket tolerates 300º F asphalt and the machines that roll it in place.

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

Mats come in two energy outputs:

120VAC mats are 38 Watts/Sq. Ft.
208, 240, & 277 VAC mats are 50 Watts/Sq. Ft.

ProMelt has more sizes and more options than any electric snow melting system. Standard size widths are 2 feet and 3 feet. You can order mats to cover from 9 to 112 square feet. Our catalog lists 60 standard sizes. Watts can make custom sizes.

Follow these recommendations when selecting ProMelt Mats:

Determine what voltage will be used: 120V, 208V, 240V, or 277V.
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.
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 in. 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 ft.-wide or 3 ft.-wide mats can be selected.

Alternatively, you might want to figure the total length of mat needed. This can be better for an area such as tire tracks, sidewalks or stairways. As an example, a sidewalk is 30 in. wide, 25 ft. long, and has a 240V power supply. The best choice would be a 2 ft. x 24 ft. mat, 240V mat.

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.
