    These easy to install kits are the answer for protecting expensive electronic units that must be installed in low temperature areas, indoors or outdoors. They operate with enclosed covers. In addition to assuring continued operation of protected units, they also keep LCD's from becoming sluggish and help them stay visible.

Both systems include a foil heater pad with adhesive backing and a thermostat to maintain a setting of 40 F (4.4 C) inside the enclosure.
