SmartOne® Electric Immersion Heaters utilize Positive Temperature Coefficient (PTC) semiconductors as the heating element. They are “self-limiting” - the maximum temperature is internally limited regardless of the operating conditions thereby providing built-in safety. As the PTC elements heat up, their resistance to electrical current increases. In the aquaculture industry, a common threat to heater life is buildup in waters with dense solids resulting in overheat conditions. Since these conditions will not cause the SmartOne® to overheat, it will last significantly longer than a traditional heater (periodic cleaning is still recommended). The maximum output temperature is below the ignition point of most plastic tanks so overheat damage is prevented if the element is operated in air or becomes covered with buildup. The EASYPLUG™ PTC heaters offer simple, easy plug-in installation; simply mount the heater, plug it into the control, and plug the control into a wall receptacle. Stainless steel models for fresh water, titanium models for salt water.
Controls sold separately. One-year warranty.
Digital Temperature Controls provide an LCD temperature display that indicates both the set and actual temperatures of the water, providing an extremely reliable and accurate temperature control for aquaculture heating systems. They can be set to display °F or °C. All controls are manufactured with UL-listed components. The Digital Combination Control, model NA30DX, consists of gasketed plastic enclosure, thermostat, contactor and replaceable Protector 1 thermal protection.
