Construction Characteristics
PHC Tubular Heaters are the most versatile and widely used source of electric heat for industrial, commercial and scientific applications. They can be designed in a wide range of electrical ratings, diameters, lengths, terminations, and sheath materials. Important and useful characteristics of tubular heaters are that they can be formed into virtually any shape, brazed or welded to any metal surface, and cast into metals. Carefully researched manufacturing methods and quality materials have made PHC tubular heaters stand apart from other heating elements claiming similar performance.
We have hight standards and take pride in all we do

Watt Density
Element Watt Density is the wattage dissipated per square inch of the element sheath surface and is critical to the proper heating of the application and to the life expectancy of the heater. The Watt Density is calculated with the following formula:
- Many materials are heat sensitive and can decompose or be dam- aged if the element is running too
- Air and other gases that are poor conductors of heat require watt densities matched to the velocity of the gas flow to prevent element
- When heating hard water or cleaning solutions mineral deposits can build up on the element sheath, acting as a heat insulator and raising the internal element If these deposits cannot be periodically removed, use a lower watt density element to increase heater life expectancy.
