Watlow Mineral Insulated Strip Heaters

MI - Mineral Insulated Strip Heaters from Watlow

Get a Quote HERE! from Sords Electric

The MI strip heater is a thin, responsive heater that uses the most advanced heater construction techniques. A nickel-chromium element wire is embedded in Watlow’s exclusive mineral insulation material, which has a much higher thermal conductivity than the mica and hard ceramic insulators used in conventional heaters. This thin layer of insulation brings the element wire closer to the heater sheath. The result is heat flows easily from the element wire to the sheath allowing the wire to run cooler than conventional heaters and increasing heater life.

Higher watt densities than any other strip heater for faster heat-up

Exclusive mineral insulation combines dielectric strength and superior thermal conductivity

304 stainless steel sheath maintains the high compaction of mineral insulation

UL® component recognition for most 240VAC or less designs

480VAC maximum voltage

Watlow Mineral Insulated Band Heaters

Sords Electric Sells Barrel and Band Heaters from Watlow

Mineral Insulated (MI) Band/Barrel Heaters

The MI band heater from Watlow® is a high-performance heater. The band heater's performance and name are derived from Watlow's exclusive mineral insulation—a material with much higher thermal conductivity than mica and hard ceramic insulators used in conventional heaters. A thin layer of the “high” thermally conductive MI material is used to electrically insulate the element wire from the inside diameter of the heater sheath. A thicker, “low” thermally conductive layer backs up the element wire directing the heat inward toward the part being heated. 

High thermal conductivity of MI and low mass construction provides rapid response to temperature control and avoids thermal lag.

Operating temperatures up to 1400°F (760°C) allows safe melting of resins such as PEEK™, Teflon®, Ultem® and Zytel®

Higher watt densities contribute to faster heat-up and throughput for increased productivity

Stainless steel cover and side fold design resists contamination from overflow of plastic or other free-flowing materials

Attached clamp bars eliminates cumbersome clamping straps, making installation easier

Strip Heaters ~ Watlow >> Chromalox

Sords Electric can provide Strip heaters.

Strip Heaters are used to heat a surface and should be clamped or banded to the surface.
The most commoN strips are 1.5 inches wide and up to about 36 inches in length and have offset terminals, meaning two terminals at one end but offset to each other. Strip heater are usually 120 volts or 240 volts.  Wattages are from 150 to 2250.

Below is a Chromalox to Watlow Cross reference
These strip heaters have OFFSET terminals at one end, hence the OT for Offset Terminals.
