Frost Protection of Freezer Room (Floors)
Selection of Load
For well insulated freezer room floors the load requirement is 3 - 5 W/Sq. Ft. Cables are spaced at 12” to 18” apart and installed in the subsurface, either in sand or directly below the insulation and tied onto mesh..
The heating cable should be controlled by use of a thermostat with a remote sensor located at the same depth as the heating cable and between two cable runs.
Use a linear load of 3½ to 4 W/ft. cable. The centre spacing will then be in the range of 15”.
Always measure the insulation and heating cable resistance before installing the insulation and the poured concrete floor.
