TUTCO CONDUCTIVE

Hi-Temp Cartridge Heaters

TUTCO Hi-Temp Cartridge heaters are high watt density heaters that provide excellent heat transfer efficiency and up to 100 Watts/in² with high operating temperatures. The Hi-Temp Cartridge is made to withstand a sheath temperature of up to 1200°F (649°C) continuously and 1400°F (760°C) intermittently. Its swaged construction allows for minimal internal air gaps, providing superior heat transfer and resistance to impact and vibration. Dual voltage and three phase options are available on selected diameters.

LEAD OPTIONS

FLEXIBLE LEADS
Internally connected leads. For applications requiring maximum flexibility at lead exit. 10” (25.4 cm) leads standard, other lengths are available.

EXTERNALLY CONNECTED LEADS
Hi-Temp Cartridges are provided with approx. 1” (25.4 mm) sleeving over lead junction as standard. 10” (25.4 cm) leads standard, other lengths are available.

STRAIGHT LEADS WITH CLIP SUPPORT
Clip support helps to minimize lead breakage where leads exit heater. 10” (25.4 cm) leads standard, other lengths are available.

90° LEADS
Leads exit at 90° angle for applications where space is limited. 10” (25.4 cm) leads standard, other lengths are available. Order heater by overall length.

90° LEADS WITH CLIP
Clip support helps to minimize lead breakage where leads exit heater. 10” (25.4 cm) leads standard, other lengths are available.

LEAD PROTECTION

STAINLESS STEEL BRAID
Stainless steel braid over lead wires. For applications requiring small radius bending and lead wire abrasion protection. 10" (25.4 cm) braid standard, other lengths are available.

STAINLESS STEEL ARMOR
Straight stainless steel armor cable protects leads from abrasion. Sizes include: 1/4", 5/16", 1/2", and 5/8". 10" (25.4 cm) standard, other lengths are available.

RIGHT ANGLE ELBOW
Right Angle Elbow Right angle copper elbow for applications requiring right angle lead exit. Moisture-resistant seal is optional. 10" (25.4 cm) leads standard, other lengths are available.

STRAIGHT STRAIN RELIEF SPRING
Straight strain relief spring minimizes bending strain on lead wires. Spring extends approximately 3" (76.2 mm) beyond end of sheath.

FITTINGS

NPT BUSHING
Hex head N.P.T. bushing attached. Must specify insert length and bushing material. Sheath material types: stainless steel, cold rolled or galvanized. Bushing material types: brass or stainless steel. Octagonal box available.

HEX CENTER BUSHING
Hex head N.P.T. bushing attached. Must specify insert length and bushing material. Sheath material types: stainless steel, steel or brass. Bushing material types: brass and stainless steel. Octagonal or explosion-proof boxes can be adapted to both Standard and Hi-Temp Cartridge heaters.

ADAPTER
Must specify insert length and bushing material. Sheath material types: stainless steel, cold rolled or galvanized. Bushing material types: stainless steel.

ADAPTER WITH HEX HEAD
Must specify insert length. Bushing material is copper.

THERMOCOUPLE

BOTTOM GROUNDED
For fast response, heater is positioned in a blind hole or where material flows past or encompasses the heater. The end disk is always welded in place. Machined flat up to 1/2″ (12.7 mm) dia.

BOTTOM UNGROUNDED
Where circumstances are such that an ungrounded thermocouple is required.

CENTER GROUNDED
Selected when a fast response is required. The thermocouple can be located in any position along the length of the heater. Standard location is midway along the length with approximately 1/4″ (6.4 mm) cold section on either side of the junction. Not available on 1/4” diameter heaters.

CENTER UNGROUNDED
The thermocouple is positioned internally and ungrounded to monitor the heater temperature. Generally used in research and development applications.

Thermocouple Availability

All heaters shown are Hi-Temp with type “J” thermocouple standard. Type “K” thermocouples are available. For standard Cartridge heaters thermocouples are available located at the bottom or center, ungrounded only.

OTHER OPTIONS

ARMOR WITH PLUG
Armor cable with power plug attached. Must specify armor length and HubbellÂ® power plug number. Moisture-resistant armor available. Other Plugs are available. Also available with Hex Head NPT bushing and armor.

BOLT HEATER
Bolt heaters are designed to heat drilled metal surfaces quickly while minimizing heat loss to surrounding areas. Each is designed to expand drilled bolts or studs while maintaining a uniform heat throughout its heated length. Typically, after a bolt is heated (expanded) the holding nut is tightened. The shrink tightness is obtained when the heater is removed and the bolt cools. This process is frequently used in the assembly and/or servicing of heavy duty equipment such as compressors, steam turbines, pressure vessels, etc.
