SmartOne® Electric Immersion Heaters

Process Technology proudly introduces the latest in innovative heating technology - the SmartOne® self-limiting PTC electric immersion heater. With this technology, thermal overtemperature protectors are no longer required to ensure safe operation. SmartOne® heaters are more dependable with extended service life and will not burn out in air, scale or sludge like traditional resistance heaters. As the trusted industry leader for over 35 years, Process Technology continues its precedent-setting tradition of providing the highest quality wet process heating and cooling equipment. SmartOne® - the new international standard in process heating. PTC Element Technology SmartOne® heaters utilize Positive Temperature Coefficient (PTC) semiconductors as the heating element. Unlike traditional heating 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.

S1 Series Smartone - Metal Over The Side Heaters S13L Series, Metal Bottom Heaters

Introducing the SmartOne® line of PTC (positive temperature coefficient) electric immersion heaters. With this technology, thermal over-temperature protectors are no longer required to ensure safe operation. PTC heaters are more dependable with extended service life and will not burn out in air like traditional resistance heaters.

Electric Immersion Heaters

Process Technology electric immersion heaters are designed for the demands of corrosive chemical heating. Open tank, screw plug and flange configurations are available. A wide variety of sheath materials ensure long life regardless of the chemistry. Materials include: fluoropolymer, quartz, titanium, 316 stainless steel, 304 stainless steel and plain steel. Sizes as small as 100 watts for laboratory environments and as large as 54,000 watts (flange heater up to 270,000 watts) for industrial applications are available. Many standard configurations are available from stock. Quick lead times are available for custom configured heaters. (Manufacturing lead times can be as short as two or three days.) Heaters are UL, CSA and CE.
