Full case – For use where surface contact on both sides of heater is necessary.		Mica Strip Heaters are also available with lead modifications fig. 3,5,6 & 16(shown) and plug configurations as shown in the Mica Band Heater section.

Watt densities to 35wi². Standard thickness is 5/32″. When ordering, specify: length and width, type of termination, wattage and voltage (resistance tolerance +10; -5%) and special features.

HD High Density Strip Heaters

The HD Strip Heater’s highly compacted refractory material quickly conducts heat from the resistance wire to the sheath resulting in low internal temperatures and long heater life in the most demanding applications. Precise placement of the resistance wire provides uniform sheath temperature across the width and along the entire heated length. Terminal designs allow easy installation wiring. 3/8″ thickness creates a rigid sheath for secure clamping ability. The HD Strip Heater is ideally suited for man industrial and commercial applications.

Highly compressed refractory material for outstanding performance in surface heating or convection air heating applications Rugged construction with high temperature and high watt density capabilitiesSheath Material: Rust resisting iron for sheath temperatures to 750°F 430 stainless steel for sheath temperatures to 1200°F

Termination

10-32 threaded post terminals offset at one end (Type A), one terminal at each end (Type B), or perpendicular to length at one end (Type C)

Ceramic terminal covers

Secondary insulators PCW-6266 and PCW-6267 are required for mounting in air heating application or when HD Strip Heaters are wired in series on line voltages above 480. Also, specify if a 9/16″ x 11/16″ mounting slot to accommodate insulator

Width: 1-1/2″ ± .020″

Length: To 53-7/8″ overall length (A
dimension)

Thickness: 3/8″ ± .02″ – .035″

Maximum Voltage: 600

Channel Heaters

A nickel chromium resistance wire is strung through and supported by a ceramic core. Finely meshed refractory material is vibrated through the remaining air voids to provide good thermal conductivity and dielectric strength. The sheath is seamless stainless steel and with proper surface contact and application considerations can provide sheath temperatures to 900°F/485°C. Because of ease of installation, Ogden Channel Heaters have been used in many industrial applications, such as platens, hot plates, dies, molds, mill slots or any place surface heat is required. Figures TF2 and TF3 can be used as air heaters or in oven applications.

Type P Protective Terminal Box Cover: On T3 Terminal only. Prevents damage to terminals from grounding, short circuiting and foreign material.

Type W without Mounting Tabs

Type L & Type R Both items have 1/2″ NPT internal threads for conduit attachment and are contamination resistant. Type L is shown with welded-on mounting tabs. Type R can also be manufactured with welded-on tabs.

Type C Armor Cable for abrasion resistant leads.

Type O Ceramic Terminal Cover: To protect against electrical shock. Wire exit at any angle. Available on Type T1 and T3.

Type S Teflon Seal: (450°F Maximum) Resists moisture or contaminant from entering terminals.

Mighty-Tuff Strip Heaters The Mighty-Tuff Strip Heater provides high temperatures, extreme watt densities and quick responses in applications where previously, any other type of strip heater could not be considered. Heat is transferred rapidly from the resistance element to the sheath for lower internal temperatures and long life. The thin but rugged design can produce high sheath temperatures at high watt densities. The Mighty-Tuff is versatile with the availability of widths to 6″ and lengths to 42″. In the most difficult application or in normal use, the Mighty-Tuff will significantly improve strip heater performance. Careful consideration in clamping strip heaters to the surface will improve heat transfer and extend heater length of service. 2-1/2″ wide Mighty-Tuff with SG terminals. SG terminals are perpendicular to the length and have 10-24 threads. Available on 2″ and wider. 2-1/2″ wide Mighty-Tuff with SG terminals and 3/8″ diameter mounting holes. 7/8″ wide Mighty-Tuff Strip Heater with SE terminals. 10-24 threads with a terminal at each end is the standard design. 7/8″ wide Mighty-Tuff with SE terminals and 3/8″ diameter mounting holes. Mighty-Tuff Strip heaters can be supplied with any lead configuration as shown on Mighty-Tuff Bank Heater section, such as Type F, C, A, R or P. The illustration is with Type C Armor Cable protected leads.

Finned HD Strip Heaters

Finned HD Strip Heaters feature the same highly compressed, rugged design as HD Strip Heaters with the addition of 1-3/8″ X 2″ fins. Fins increase the heat transfer surface area to allow higher wattages than standard HD Strip Heaters. Rust resisting iron sheath items are standard with aluminized steel fins. Stainless steel sheath items are standard with stainless steel fins. Convection heating or processes requiring a high velocity air stream are among the many possible applications for Finned HD Strip Heaters.
