This Product group is an excellent choice for direct insertion heating of platens, dies, various metal shapes and products requiring maximum amount of heat within a limited or short space. With the addition of either threaded or leak tight mountings/fittings these heaters are also an excellent choice for direct immersion into liquids.

[Cartridge heater]

 
Heater diameter is varying precise in designing the heaters. Units without mounting /fittings are designed to fit holes with a diameter tolerance of + .0254 mm - minus. 000 of nominal heater diameter. For example a heater of 12.7 mm i. e. ½"diameter is designed to fit a hole size of 12.71 mm -0.000". Higher rated watt densities on the heaters combined with larger hole clearances will reduces the heater life.

Holes preferably rimed to accept heaters should be rimed all the way through are advisable. Corrosion or scaling may make heater replacement difficult in blind holes.

Do not allow the heated portion of heater to operate in air or an air pocket. Do not operate any standard cartridge heater in open air.

Straightness or total run-out along the axis can be held to plus or minus 0.5 mm per 25 mm for length upto 100 mm & 1 mm per 25 mm upto 300 mm. Heaters are normally flexible enough to fit into long holes.

Heaters installed into moving blocks or dies should have provisions for preventing the leads from being damaged from motion.

Cartridge heaters with liquid tight mountings/fittings could be used for liquid application. Heaters mounted in a tank or vessel should be mounted horizontally near the bottom. Heater must be in liquid all the time. Product, process, or system should include a device to protect heater from operation if no liquid covering the heater. System should be designed to avoid air entrapments or pockets of overheated liquid around the heater.

Heating performance can be improved by agitation of liquid in the tank. In all cases, due to normal high temperature attainable on any metal-sheathed heater, avoid contact with combustible surface or materials.

As with any electrically heated product, the proper application of heater and temperature control is the most important factor in optimum performance, efficiency. No two systems are alike It is extremely important that attention has been given to the total product or system design as well as operating environment.

The component tubular heaters depending on the mounting provisions and configurations are suitable for use in solids, liquids, air as well as gases. These heaters provide the most design versatility of any electric heater construction. Tubular heaters because of their compacted MgO insulation construction can reach fairly high sheath temperatures, however the successful application of these heaters are primarily dependent on the end use.

A major advantage of Tubular heaters is the ability to form into custom shapes. Bend in radius as small as twice the tube diameter depending on the tube material, configuration and application.

Solids heating can be accomplished by clamping of Tubular heaters to the heated object surface. Good surface contact is required in order to prevent localized overheating. Due to round cross section of the heater, it is always advisable to put a groove into the solid and the heater is pressed into the groove. Heaters can be configured with a flat surface pressed into the heater surface certain shapes limitations are applicable.

Tubular heaters are often cast into Aluminum for broad surface coverage and uniform heating application requirements.Liquid heating requires the use of leak tight mountings/fittings provisions for direct immersion. Threaded mounting fittings, flanges, brackets and custom mounting attachments are used for this purpose and often include custom element shapes. Heater sheath corrosion resistance and watt density (the amount of wattage spread out over the available heater surface area = Watts/Sq. Inch.) are important factors in designing and applying the proper heater.

Air and gas heating Tubular heaters designs typically incorporate low watt density constructions or finned designs. As I most heater applications the watt density is critical to ensure heater temperatures are maintained within limits of the product capability. All finned tubular and duct heaters are suitable for air applications. Depending on the conditions some bushing, flanged and circulation heaters may also be used for heating air.

In all cases due to normal high temperature attainable on any metal-sheathed heater avoid contact with combustible surface or materials.

As with any electrically heated product, the proper application of heater and temperature control is the most important factor in optimum performance, efficiency and longevity i.e. longer life. No two systems are alike It is extremely important that attention has been given to the total product or system design as well as operating environment.

Strip heaters without fins are designed for contact heating. They are used in a verity of applications including mounting to the outside of tanks/container surfaces for heating of liquids and solids. They are also used for direct heating of platens, dies and other flat metal shapes and solids.

It is extremely important that heaters are mounted on a flat, smooth and clean surface with good contact maintained between the heater and the mounting surface. Air gaps between the mating surfaces will result in a reduced heat transfer and possibly shorter heater life due to resulting higher heating temperatures.
[strip heater]

When surface mounting strip heaters allowance must be made for liner thermal expansion of heater. A common method of allowing liner thermal expansion is to firmly tighten the mounting bolt on one end and alllow the heater to expand within the confines of the mounting bolt on the other end of strip heater.

Care should be taken not to overtightining/torquing the screw and nut terminal posts as breakage of the internal heater connections may occur. Also connections of heater are usually made with high temperature wire.
