Electric Immersion Heaters have internal temperature regulation.

May 4, 2011

SmartOne(TM) positive temperature coefficient electric immersion heaters utilize solid-state ceramic heating elements as heat source. Maximum temperature is internally limited regardless of operating conditions, whether units are operated in water, air, or surrounded by solids. With maximum output temperature below ignition point of most plastic tanks, products do not overheat even when covered with buildup. Periodic cleaning of buildup minimizes risk of chemical corrosion.
