2" TUBULAR SCREW PLUG PTC HEATERS
2' TUBULAR SCREW PLUG PTC HEATERSSmartOne heaters utilize Positive Temperature Coefficient (PTC) semiconductors as the heating element. Unlike traditionalheating elements, they are SELF-LIMITING. As PTC elements heat up, their resistance to electrical current increases.You may already be familiar with PTC technology as it is used in hair dryers, curling irons, and car seat heaters.FEATURES AND BENEFITSIncreased Safety SmartOne heaters can only reach a set maximum sheath temperature which is below the ignition point of mostcombustible materials (such as plastic tanks, see chart below). Unlike traditional immersion heaters with external thermal protectors, the safety of thermal protection is built intothe design of the PTC chips. Therefore, it is impossible to bypass thermal protection.Longer Lasting SmartOne heaters are not affected by low solution level conditions, scaling solutions, or sludge buildup. Unlike traditional heaters, SmartOne heaters limit their heat output so they will not overheat or burn out.VersatilityThree voltage ranges are available: 100-120 volts, 200-240 volts, and 380-480 volts. The need for derated heaters for viscous solutions is eliminated because SmartOne heaters internally regulate heat output to match the environment.Available in 304 stainless steel, 316 stainless steeland titanium. Easy Installation & MaintenanceNo external thermalprotection devicerequired.No additional wiringneeded for thermalprotection devices.No equipment downtimedue to thermal protection maintenance.Notes:Temperaturecontrol is required to regulate process temperature.Liquid level shut-off device recommendedAs with any heater, periodic cleaning is recommended.Scale and sludge can increasethe rate of chemical corrosionon the heater sheath.
