Because you need a modest snow melting system – perhaps pilot duty sized – and you’re looking for an ideal controller for it, look into Environmental Technology Inc.’s Snow Switch® Model PD Pro, the ice and snow detection and melting system control for use in pilot duty applications, up to 7 amp inductive loads.

ETI has expanded its input voltage range, now between 100 to 277 VAC, making it useful for nearly any situation. The PD Pro is the snow and ice control for medium-sized applications whose features and power needs do not require an APS or EUR Series control panel.

This new power range is found in its companion product as well, the Snow Switch® Model GF Pro with integral 30mA Ground Fault Equipment Protection (GFEP).

In its weather-resistant NEMA 4-X enclosure and weighing a mere three pounds with a footprint about the size of a half-sheet of paper, the improved PD Pro now operates at ambient temperatures between –31° and +113°F (–35° to +45°C), broad enough for modest weather event management. It can be operated through manual-override operator controls as well.The PD Pro’s adjustable Hold-On timer can be set at the unit from no time to 8 hours for flexibility in managing a weather event’s impact. This control feature allows snow melt management systems to leave protected surfaces completely clear and dry, regardless of how long it might take. Manual initiation or cancellation of the heating cycle is another PD Pro feature.
