Mighty Watt ® Cartridge Heaters

The Ogden Mighty Watt is an elite category of high density cartridge heaters. No other swaged cartridge heater is compacted to the extent of the Mighty Watt, producing excellent heat transfer capability and the dielectric and physical strength necessary for long life and outstanding performance. The Mighty Watt is designed for applications where high operating temperatures are required, or where heaters are subjected to vibration. Because the construction allows maximum heat transfer and high temperatures, it is possible to use fewer heaters at higher watt densities to reduce space requirements. The Mighty Watt is available from 1/8" to 1-1/4" diameters in just about any conceivable increment. With designed-in quality and reliability, the Mighty Watt is the ideal heat source for any process.

Mighty Watt Plus ® Cartridge Heater

The Mighty Watt Plus allows one of nine lead modifications to be added to any of over 700 Mighty Watt Cartridge heater sizes and ratings available from stock. This creates many thousands of possible combinations-shipped within 2 days! Rather than waiting through normal lead times or inventorying numerous spare parts, the exact item necessary can be on the job quickly...essential for meeting today's manufacturing requirements. The Mighty Watt Plus modification can be added to any stock item in 1/4", 3/8", 1/2", 5/8" or 3/4" diameter with any lead length desired. All Mighty Watt Plus items use high temperature lead wire rated to 850°F(450°C).

Any of the Mighty Watt Plus modifications can be added to the base cartridge heater. With minimal sheath extension, several styles of lead protection, fully flexible or other lead designs can be applied virtually as quick as the standard crimped-on lead connection.

SST and QST Split Sheath Insertion Heaters

The SST and QST Split Sheath Insertion Heaters are designed especially for platen, die or mold heating applications where the holes are poorly drilled or worn through age. Independent expansion of each section of the SST and QST when energized, creates intimate contact with the wall of the hole. SST Insertion Heaters have a single split along the length. The two sections expand in opposite directions. Conductive heat transfer is excellent. The QST, or Quad, has additional sections that expand in four directions. Surface contact is superior to any available insertion heater. The simple internal design of the SST and QST generates a uniform linear temperature profile. Perhaps the most outstanding feature is how easy the SST and QST Split Sheath Insertion Heaters are removed from the hole for replacement or other servicing requirements. As the temperature cools, the sections contract, allowing the SST and QST to slip from the hole without difficulty. In platens and presses utilizing long, conventional cartridge heaters, Ogden's split sheath design can reduce down-time and maintenance costs. Where repair or redrilling of the hole is not practical, the SST and QST offer outstanding performance.

Bullet ® Cartridge Heaters

Ogden's economical Bullet Heater is designed for high volume production, for low to medium watt densities to 100 watts per square inch and 1000° F sheath temperature. The swaged construction offers efficient operation and long life for applications where the high watt density capabilities of the Mighty Watt are not necessary. The BL Series features 12" flexible lead wires mechanically crimp connected to solid nickel pins. The BX Series offers 12" fully flexible fiberglass insulated lead wires. Any lead configuration from the previous Mighty Watt pages are available on the Bullet.

Maxi-Zone® High Temperature Insertion Heaters

Designed for hot press metal forming applications, the Maxi-Zone High Temperature Insertion Heater produces continuous sheath temperatures to 2000°F/1095°C. An Inconel^® 600 sheath allows efficient operation at extreme temperatures. Because of this capability, many applications will observe considerable performance improvements with the Maxi-Zone versus other heat sources.

A unique feature of the Maxi-Zone is to provide two or three independently controllable areas along the sheath length. Precise temperatures can be produced in every location by arranging the process in multiple zones and monitoring and controlling each separately.

The Maxi-Zone's primary heat transfer method is by radiation. The continuing oxidation of the sheath and inside walls of the hole at these temperatures produce excellent transfer of heat. This emissivity improves with usage, allowing sheath and process temperatures to be nearly identical. Diameters are substantially undersized versus standard cartridge heater applications. A .935" diameter Maxi-Zone would be applied in a 1" or larger hole. A Maxi-Zone is easily removed and replaced. Standard Maxi-Zone diameters are .495", .685" and .935" with lengths from 18 inches to 15 feet. .210" diameter Inconel^® 600 sheath tubular heaters are available for heating ceramic presses in similar applications.

Bolt Heaters

Designed primarily to pre-heat large, drilled holding bolts or studs. The Bolt Heater is used in the assembly or servicing of hydraulic presses, die blocks, steam or pressure vessels, turbines or other equipment where a high concentration of heat is needed to expand, then wrench tighten tie rods. The parts cool and contract, resulting in the nut being drawn even tighter.
