Knowing which strip heater to use in order to maximize your efficiency can be difficult. Heater life, start up time, process temperatures, durability, size, and cost all play an important role. While reviewing our guidelines on which strip heater to choose for you particular needs, keep in mind that every application will have its own set of unique challenges.
Mica Strip Heaters
Mica strip heaters can be custom manufactured in 1 - 2 days. They can be manufactured to a wide range of lengths and widths. Both post terminals and lead wires are available. They are suited well for medium to high temperatures but should be designed at low watt densities.
Channel Strip Heaters
Channel strip heaters have long lead times. The length/width options are more restrictive than mica and are suited well for mid to high temperatures.
MI (Mineral Insulated) Strip Heaters
MI (mineral insulated) strip heaters have long lead times. They have restricted lengths and widths. Several termination options are available. Good for high temperatures and high watt densities.
Refractory Strip Heaters
Refractory strip heaters are available from stock in many lengths and voltage/wattage combinations. They have restricted length/width combinations and are suited well for high temperatures.
Finned Strip Heaters
Finned strip heaters are channel strips with metal fins added to aid in heat dissipation. They have restricted length/width combinations. They are suited well for air heating applications.
Extruded Aluminum Strip Heaters
Extruded aluminum strip heaters have long lead times. They have restricted length/width combinations. They must run at lower temperatures (max heater temp. of 600° F) but are very rugged and stand up well in the presence of contamination.
Cast or Plate Strip Heaters
Cast or plate strip heaters have long lead times. They can be manufactured to a wide range of lengths and widths. They can operate at high temperatures and are very rugged.
