Micanite Band heaters


GENERAL CHARACTERISTICS:

The mica band heaters, because of their multiple uses, electric heaters are made ​​of a thin sheet mica that isolates the internal circuit completely wire resistive nickel-chromium (Ni-Cr) from the inner surface of the diameter of the shell-structure metal steel / stainless steel that protects the heater from accidental impact.

For this reason, this type of mica heating elements is well suited to many applications that require heating, on contact, no standards for operating temperatures above 280 ° C.

The coupling of various combinations of materials in the construction of this resistance enables them to achieve high performance in relation to the specific application and the operating temperatures required. In addition, the thin sheet of mica allow optimal heat transfer and, simultaneously, limiting the temperature reached the resistive wire, resulting in a lengthening of the useful operating life of the heater.

Sterilizers, confectionery industry machines, wood-working machines, wrapping and packaging machines, textile industry machines. The quality of the raw materials used, as well as the experience and the extreme care with which we are assembled, make this type of electric heaters of proven efficiency and reliability.

Made of various diameters, Mica band heaters wrapped perfectly the diameter of the cylindrical surface to be heated, ensuring effective radiant heating on the body to be heated, thanks to a good and a good heat exchange surface density (W/cm2).

This graph shows the energy saving of around 20% obtained when using heaters, mica band than with mica insulation. This result is the result of a laboratory test after 24 hours of continuous work.

Advantages:

Uses:

The rules for the application of a resistance band mica are the type of support that will host and temperature that will endure.

Among the main applications of the typical electrical resistance band Mica, remember:

CERTIFIED QUALITY PRODUCTS

The Mica band resistors entire production cycle is subject to the strictest dimensional checks and electric tests in compliance with the standards set forth by our own ISO 9001:2015 certified Corporate Quality System, and in full compliance with the CEI/EN requirements in force.

The various operating temperatures require different combinations between external sheath type and internal insulation, among the ones listed below it is possible to select:

Operating temperature External sheath Internal insulation Electric contacts finishing
100° C Anodized iron Micanite Cables/ Pins/ Clamps
200° C Anodized iron Micanite Cables/ Pins/ Clamps
300° C Anodized iron Micanite Cables/ Pins/ Clamps
400° C AISI 304 Ceramic/ Micanite Pins/ Clamps
500° C AISI 321 Ceramic Pins/ Clamps
600° C AISI 321 MGO/Ceramic Pins/ Clamps
700° C AISI 321 MgO Pins/ Clamps

The combinations referred to above are those commonly used in various applications, the temperatures specific for each type.
Improper use of the heater with respect to the initial design release the manufacturer from any liability.

USEFUL DESIGN DATA

The construction of an electrical resistance band mica requires knowledge of the technical data essential to the design:

TYPE OF EXECUTION (Electrical contacts and attachment / mounting system)

The electrical resistance band in mica insulation can be made ​​taking into account two different parameters:

Resistors standard catalog

This type of mica band heaters can be built to customer specifications is that in the standard version, which we have a warehouse ready for the type of power, voltage, sheath diameter and type of finish.
