PRODUCT SPECIFICATIONS
Installation. . .
The SRFN heaters are a flat heater measuring 100mm
wide X 1.5m & 2.0m long models with a 15mm high
flange along each long side to assist in directing snow
and ice melt away from the switch. These heaters are
rugged, yet flexible enough, to be easily adapted to the
requirements of a given rail switch rod installation.
Simple wire nut connections are made inside the box for
power connection.
Construction. . .
Inside the SRFN heater is a rugged, parallel path
resistive heating element that is encapsulated between
two layers of high temperature fiberglass reinforced
silicone rubber. This encapsulated element is further
encased between two galvanized steel panels for further
durability and protection. A Nema 4, junction box with
ground terminal and side entry to receive a rain tight
conduit fitting is mounted at one end of the heater.
