Straight Tubular Heating Element

Description

Tubular electric heater is made of a metal tube as the shell, and spiral electric heating alloy wires are uniformly distributed along the axial direction of the tube. The gaps are filled and compacted with magnesium oxide powder with good insulation and thermal conductivity, and both ends are sealed with silica gel or ceramics. It can heat air, metal molds and various liquids.

Straight Tubular Heating Element use high-quality Copper/SS304 /SS321, /SS316L/Incoloy800，etc It has good corrosion resistance , high mechanical strength,long service life.

Under the same power condition,tubular heating element has the advantage of fast heating,High thermal efficiency,heat evenly,stable performance.

Straight tubular heating element for corrosive is widely used to heat liquids, air or metals as a reliable, economical, and versatile way, which can be used in a large variety of applications, including those with size restrictions for small spaces. They allow for even heat distribution as well as a high dielectric strength. Tubular heater can be formed into a variety of patterns.

Tubular heater makes the heating of complex platens, shapes, and machines, possible. Flexible tubular heaters are completely flexible, and may be shaped at will. Around pipes, along platen paths, and other challenging shapes. Excellent replacements for traditional tubular heater, which are not flexible and most can be custom made in most cases.

Data Sheet

Features

Tubular heating element (calrod heating elements) is highly adaptable to most applications where electrical heating is required. They can be used in their straight form or bent into various shapes. Tubular heaters can be used in free air, clamped to a surface, placed inside a groove or cast into metal.

Product detail

Application

Tubular elements of proper rating, material and shape can be applied to most heating applications requiring process temperatures to 750C (1382F).Tubular elements may be clamped, immersed, cast into metal or spaced away from the work as radiant heaters. Elements can also be positioned in ducts or vessels for heating air or other gases.

Check factory for recommendations if you are unsure of the suitability of the heater to your application.

Installation

The terminals must be protected at all times from moisture or vapour. In hazardous locations, explosion resistant terminal housings must be used. In outdoor locations, moisture resistant housings are required.

Protect terminals of heating elements from drippings, condensation, fumes, spray or any other substance which could result in element contamination and subsequent failure.

When melting solids by direct immersion, a surface vent should be provided to allow gases to escape. Operate the heater at voltage until melted material completely covers the heating elements. Heaters used for this purpose may require special design features. Check factory for recommendations.
