Waukesha® Positive Temperature Coefficient heaters can improve the reliability, efficiency and operational life of electrical equipment by automatically maintaining an enclosure temperature only slightly higher than the outside ambient temperature without using a thermostat or controls. Our PTC2 performs this function better than the original PTC with a higher velocity fan, all while taking up less space and having no need for any special mounting platforms.
Our PTC2 heaters use a variable resistance (current limiting) material that automatically controls cabinet temperature and eliminates the need for a thermostat, increasing heater reliability and efficiency.
During cold weather when significant heat is required to reach the thermostat setting, a traditional strip heater is likely to drive the temperature of the area around the heater well above desirable levels. This can result in uneven heat distribution in the control box. Waukesha's PTC2 heaters feature an integral circulating fan that moves warm air around the cabinet, maintaining even heat distribution and providing uniform condensation protection. The PTC2 offers even better air velocity than the previous PTC, allowing for even more air movement throughout the cabinet.
The electrical connections from the fan to the heater are pre-wired, so the only connection necessary is to provide power to the assembly; our PTC2 heater includes a 12 foot long wire harness with quick-connect end for easy installation. Integrated DIN-rail mounting clip allows for quick orientation in cabinet for proper air circulation; panel mounting bracket/adapter is also available for easy retrofits.
