Product Overview

Sample Application Drawings
Electric
A snow melting system is heated using electric
cables. When snow or ice is detected, the control
activates an electrical contactor, which in turn
energizes the electric cables to heat the slab surface
to the melting temperature.

Hydronic Boiler and Mixing
A snow melting system is heated using a hydronic
boiler and mixing valve. When snow or ice is
detected, the control operates the boiler and
mixing valve to heat the slab surface to the melting
temperature. The mixing valve protects the boiler
from damage caused by cold return temperatures.
Steam-to-Glycol Heat Exchanger
A snow melting system is heated using a modulating
steam valve and steam-to-glycol heat exchanger.
When snow or ice is detected, the control modulates
the steam valve position to heat the slab surface
to the melting temperature.
