Features Wide temperature range: 30° to 110° F Fixed 3 degree temperature differential Can be used with millivolt, 12, 24 and 120 volt...

This single stage thermostat comes prewired with an 8' grounded Plug in power cord. Simply plug the thermostat into a standard 110/120 volt outlet. Then plug any 110/120 volt appliance into the outlet on the plug of the thermostat. Select heating thermostat to control a heater or cooling thermostat to control fans and/or louvers. *Plug-in thermostats can not be used with our gas heaters. They require 24 volt thermostats. Features Wide temperature range: 30° to 110° F Fixed 3 degree...

Bayliss power tube life is not infinite. Over the years, the piston moving through the seals gradually wears the seal material away, allowing a gradual seepage of wax out of the tube. This in turn reduces the pressure within the tube and eventually the opening distance achieved will be affected. This is when you need to replace the power tube cylinder.Bayliss MK7 power tubes are available with 2 different models. The only difference is the operational temperatures of the power tube. The Orchid...

Replacement Aspen pads for evaporative air coolers. Just select the model cooler you have. You will receive a set of 3 pads which includes 2 for the side panels and 1 for the rear panel.

This cylinder tube powers the Gigavent automatic openers with no need for electricity. It contains a mineral wax which expands with heat. This pushes a piston which opens the auto vent via a balanced linkage. As the temperature drops, the wax shrinks and a strong spring closes the vent and resets the piston.While this cylinder for the Gigavent automatic vent opener lasts a long time, eventually the piston rod moving through the seals will wear the seal material away, allowing a gradual seepage...
