Mica insulated strip heaters are economical heat sources, suitable for providing heat to flat surfaces. The sheath temperature is limited to 900°F. Maximum allowable watt densities with respect to application temperatures are shown in the diagram. However, 20 Watts/in² is a safe value.
In order to avoid thermal expansion issues that detach mica strip heaters from the surfaces that they are applied to, strip heaters can be made to include several mounting holes or pressure plates that provide rigidity and improve heat transfer uniformity as well.
Mica insulated strip heaters are available in many electrical termination styles, and within certain desiglimitations can accommodate holes and cut-outs.
The ceramic strip heaters consists of a stainless steel sheath containing a high-temperature ceramic insulation and a nickel chrome wire coil.Magnesium Oxide is used to fill any air pockets, thus providing the best heat transfer possible. The terminals are constructed of stainless steel and the ceramic strips are available with or without location slots.
It is designed to withstand temperatures up to 700 degs C. The heater consists of a Sq Section Incoloy 800 sheath which allows good heat transfer and contains a high-temperature Nickel Chrome wire coil. Magnesium Oxide is used between the element and casting as an insulation and also providing the best heat transfer possible. The terminal options are M4 Threaded terminals or leads fitted direct. These heaters can be made to specific wattages & voltages upon request
The Ceramic Finned Strip Heater has been designed to provide excellent heat transfer to air. Used mainly for applications where an airflow is present, such as Shrink Tunnels, Duct Heaters, Commercial Fan Ovens, Space Heating. Our Ceramic finned heaters are made to order to customer’s requirements. Wattages and voltages can be specified to suit your needs.
