In 1947, Ed Jay and his partner Rudy Hentz went to work on producing a better heat source for liquid asphalt. The goal was to create a cleaner, safer, more reliable source of heat that could be used to maintain temperature in a wide variety of industrial products. Until then, industries that used process heating systems could only choose between fossil-fuel-fired or steam-heating units that were prone to maintenance problems, unreliable, inefficient, environmentally unsound and that damaged the materials being heated. With their development of consistent, electric, low watt-density resistance heat, Process Heating Company was formed. Our patented components allow our Lo-Density® drywell-style immersion heaters to dissipate heat evenly, spreading it out over large surface areas while keeping the sheath’s temperature low. This leads to long element life and the virtual elimination of damage to the products being heated.
