Thermocube

Buying Guide: Temperature-Controlled Outlets

Outlets and Converters
The Thermocube line includes both thermostatically controlled outlets and outlet converters. Both switch power on or off automatically according to outside ambient air temperature, so power is used only when temperatures require it. Five models are offered with different temperature ranges, so you can choose the one that suits your application.

Common Uses
These units suit unheated areas where equipment needs warmth. Typical applications include engine heaters, RVs, heat tapes, heat lamps, pump houses, livestock water tanks, boats and water pipes. They plug into a 120-volt receptacle or an extension cord.

Before You Buy
Confirm that your equipment runs on 120-volt power and stays within the 15 amp standard outlet rating noted for these units. Match the model number on your old part if you are replacing one. Follow the manufacturer's instructions for your equipment.
