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:

• High heat, seen as effective and uniform heat transmission, as well as a limited time to reach the required temperature range, due to the fact that these strengths are working in direct contact with the surface to be heated.
• High electrical insulation
• Constant efficiency over time and extended useful life
• Dimensional accuracy
• Very robust
• Easy installation (thanks to hooks, springs, etc..)
• Integration of temperature sensors
• Easy cleaning and maintenance
• High mechanical resistance to tearing of the connection and impact

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:

• Extruders and melting plastic, plastic injection nozzles, nozzle casting
• Storage drums, pipes, hot water boilers
• Sterilizers, machines for the confectionery industry, wood processing machines, packaging machines and packaging machines for the textile industry
• Heaters and heating contact of cylindrical containers of various types for indirect heating of fluids and / or other materials.

PRODUCT QUALITY ‘CERTIFIED

The entire production cycle of band heaters mica is subjected to the strictest dimensional controls and electrical tests in accordance with regulations of our Company Quality System certified to ISO 9001:2008 and in full compliance with the requirements of current standards IEC / EN.

The various operating temperatures require different combinations of type of interior insulation and outer shell, which we report, followed by some tips from our experience:

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 9001:2008 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::

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:

• Quantity: Specify amount requested
• Diameter (Ø): internal diameter range
• Height (H): high-end
• Power (W): (Note: the total power is equal to the sum of the 2 parts (half circles) that make up the complete body of strength)
• Supply Voltage (V)
• Wiring Type: specify type and location of electrical contacts
• Attack Type: Specify the type of attack (hook, spring, etc. …) to choose between finishing our standards (for details see data sheet “download area”
• Other: Size and position of holes for thermocouple, resetting the thermostats temperatures (where required on-board resistance) and any other specific technical feature.

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:

• Type of electrical contacts to be installed on the body resistance
• Attack type fastening / assembly system to predict the construction phase of the resistance
