Immersion Cartridge Heater

Termination Options
 

• Swaged-in Flexible leads

Swaged-in flexible leads, with silicone-fiberglass insulation, are recommended for applications in which the leads must be bent at the exit point from the heater.
Unless longer length is specified, 250mm (10 in.) leads are supplied.

Heaters 150mm (6 in.) or shorter generally have a 6 mm(1/4 in.) no-heat section. Heaters up to 250mm (10 in.) require a 25mm (1 in.) no-heat section. Heaters greater than 250mm may require more than a 25mm no-heat section. To order, please specify swaged-in flexible leads.

• Right Angle leads

Right angle leads are used in applications with a high degree of flexing and when space limitations are critical. Lead wires exit at a 90° angle through the side of the heater sheath.

Right angle tube may be necessary on certain constructions.To order, specify right angle leads and lead length.
  

• Stainless Steel Braid

A stainless steel braid is designed to protect leads from abrasion against sharp edges.
When the leads exit straight out, the braid is swaged into the no-heat section of the heater. When the leads exit at a right angle, a crimp connector is used to attach the braids.
Unless otherwise specified, leads are 250 mm (10 in.) and the braid is 200 mm (8 in.) long. To order, specify either straight or right angle stainless steel braid, lead length and no-heat section.

• Stainless Steel Hose

Stainless steel hose provides the best protection against abrasion from sharp edges or abrasive equipment. It also offers ease of handling and wiring in abrasive environments.
When the leads exit at a right angle to the heater, the hose is silver soldered to the sheath. Unless otherwise specified, leads are 250 mm (10 in.) long and the hose is 200 mm (8 in.) long. To order, specify stainless steel hose, lead length and no-heat section.
  

• Galvanized Conduit

Galvanized conduit equals stainless steel hose in its abrasion protection.
The conduit is attached with a 90° elbow copper coupler, which overlaps the heater sheath. Unless specified, 200 mm (8 in.) conduit is supplied, leads are 50 mm longer than the conduit. To order, specify galvanized conduit, lead length and no-heat section.
  

• Ceramic Bead Insulation

Ceramic bead insulation protects the leads from high temperature ambients above 450°C (840°F). The beads fit over solid conductors and are extended long enough to reach a cooler area where flexible wires can be attached. To order, specifyceramic beads and length, and additional lead length.

• Flanges

Stainless steel flanges are a convenient mounting method as well as a way to position a heater within an application. Flange style according to customer requirements . These flanges can be located in any no-heat section of the heater sheath. To order, specifyflange, flange size and location.

Immersion Cartridge Heaters

For liquid immersion heating applications, use brass or stainless steel threaded bushing.

The size of threaded bushing is matched according to pipe diameter. The specifications of threaded bushing include G thread, NPT thread, BSPP thread, etc.

How to install cartridge heater

• make a hole in the section that is to be heated

• ream a smooth hole for contact and for better heat transfer

• extend the hole through the section so that the unit can be driven out if you should need to remover it.

• if making a through hole is impossible ,increase the size of the hole without exceeding the tolerances

• Reduce the vibration and flexing of the lead wires to prolong service life

• prevent contamination from liquids by protecting the end of the heater
