Overview

The PALS De-icing system consists of a factory pre-wired control unit, heater pads for reflector coverage. AII systems are engineered to be easily assembled, installed and operated. 
The control unit has three modes of operation: Automatic, Manual Off, and Manual On. The Automatic mode allows the control to monitor the ambient temperature and sense the presence of precipitation. An ambient temperature of fewer than 4 degrees C and the presence of precipitation activate heaters. The heaters will remain on for a factory preset time of one hour longer than conditions warrant. Control units are factory preset to operate on 120 to 240 volts single or three-phase powers. The larger systems have a control unit with a remote snow sensor. 
The heater pads consist of heater wire sandwiched between layers of aluminum foil and high-density isolation material under outdoor ecstatic fabric. Heater pads allow for a faster installation without the need for templates. Watt density of the heater pads, depending on the reflector, is standard 360 w/m2 with 700 w/m2 high version. The aggressive acrylic adhesive adheres to a variety of substrates and will not release when pad temperature increases. Heater blankets have water-resistant military-compliant connectors that plug into the cables from the control unit. 
* PALS PAC-550 antenna control unit is compatible with PALS De-Ice System and can directly control the latter without PALS De-Ice Controller.
