Strip heaters are used principally for convection-type air heating and clamp-on installations. When selecting strip heaters for either, two important factors must be considered: The proper sheath material for resisting any rusting and oxidizing inherent in the process or environment and for withstanding the sheath temperature requiredThe watt density of the heating element, or watts per square inch of heated area. This should be low for heating asphalt, molasses and other thick substances with low heat transferability; it can be higher for heating air, metals and other heat conducting materials.
Our Ceramic Strip Heaters offer a high level of performance and reliability, with the ability to reach extremely high temperatures of up to 600°C (1112°F) and a power density of up to 35-40 W per square inch, making them suitable for a wide range of industrial and commercial applications.
Our Finned Strip Heater feature a high-quality design, with nickel-chromium tubular resistance wire uniformly distributed and embedded in refractory material to ensure efficient heat transfer. The refractory is compressed to maximum density and baked at high temperature to optimize heat transfer from the coil to the sheath, which is made of corrosion-resistant iron or chromed steel. The addition of aluminized steel fins further enhances heat transfer to the air, making the elements highly effective and replaceable individually.
