Strip heaters, often considered component heaters, are a simple way of using surface area to transfer heat effectively. A fairly inexpensive way of heating surfaces or small areas, strip heaters are an excellent solution to meet any budget. If strip heaters are used as a radiant heater, they have can have fins to maximize surface area and heat transfer to the air.
Construction
Mica Strip Heaters are constructed by winding a nickel-chrome resistance ribbon around mica insulation and encapsulated in a stainless steel sheath. They are available in an extensive variety of sizes and shapes with options for holes, notches and cut-outs. A number of threaded terminals, wire lead options and terminal boxes offer great flexibility for field wiring. These heaters are ideal for plastic processing applications and for anywhere heat is needed on a flat or curved surface.
FEATURES
- Heat up time is fast to provide a quick response to control input
- The flat inner resistance ribbon generates a broad area of overall heat to put the heat source close to the work
- Quality assembled winding and spacing of ribbon ensures maximum heat transfer and heater longevity
- The Stainless Steel sheath is treated so that the surface allows the increase of heat transfer to retard oxidation
- The Mica insulation also withstands high voltage temperatures, resist moisture, and remain immune to most chemicals
- The Aluminized Steel sheath is rust resistant, durably rigid, and generates heat well
MOUNTING SUGGESTIONS
Maximize your mica strip heater, by ensuring the following tips.
- The surface to be heated needs to be kept smooth and clean, for best heat transferring. Caution: Gaps can cause hot spotting
- Terminal post nuts should not be over tightened, while posts should be securely riveted to the elements. Caution: Excessive torque can break the connection
DERATING TIPS
- Heaters mounted less than 1 inch apart on a metal base: derate by 5%
- Heaters mounted within 3 inches of a reflective surface: derate by 10%
- Heaters mounted 2-6 increase apart, that radiate toward each other: derate 10%
- Heaters mounted within one inch from reflective surface(s): derate by 20%
- Heaters mounted under 2 inches apart, and radiating towards each other: derate by 20%
