TRENT Water Immersion Heaters are designed to give years of trouble-free service as long as they are completely covered with liquid and used on correct voltage. CONSTRUCTION:

All TRENT Screw Plug Water Immersion Heaters are furnished with brass heads (National Pipe Thread) to which a brass or copper sheath is silver soldered. The helically coiled heating element is supported in the tube/s by ceramic cores and/or the highest grade dielectric filler material material. The RA and RB Series come standard with a 4” octagonal outlet box. RA-Series heaters have a 1” pipe thread, and 1” copper tube. RB-Series heaters have a 1-1/4” pipe thread, and 1” or 1-1/4” diameter copper tubing. Both series have ceramic cores which support the coiled heating element. A Cap with BX connectors can be supplied upon request.

The TRS and TS Series use a dielectric material to support the coiled heating elements and the heater tubes are pressed to increase thermal conductivity. TRS Series heaters come standard with a 4” octagonal terminal box, a 2” pipe thread and are supplied with two (2) hairpin, copper tubes, nominally 1/2” in diameter. TS Series heaters are standard with a 6” square terminal box, a 2-1/2” pipe thread, and three (3) 1/2” diameter hairpin, copper tubes (designed for 240 and 480 volt, three phase).

TRENT Oil Immersion Heaters are designed to give years of trouble-free service when the tubes are completely covered with fluid, used on correct voltage and kept free of carbonization. These heaters listed as having watt densities (W.P.S.I.) of 16-22 are designed for use with heat transfer oil and have a maximum operating temperature of 550° F. Those heaters having lower W.P.S.I. are designed for use with Bunker C fuel oil preheaters and line and suction heaters with a maximum operating temperature of 250° F.

The TSO and TSOL Series have three (3) ½” diameter tubular heating elements, a steel head with a 2½” pipe thread, and come standard with a 6” square terminal box. These heaters can be supplied for three phase 240, 480, or 550 volts.

TRO,TSO or TSOL The FO Series heaters have a 7½” O.D. - 150# or 300# aluminum flange, HEATERS to which a longitudinal, finned, aluminum tubing is welded. The longintu- dinal fins increase the surface area, thus lowering the watts per square inch (W.P.S.I.), and enabling a higher KW to be used in a shorter length. Heaters are supplied complete with a 6” square outlet box. Heaters are available in three phase 240, 480 and 550 volts with optional vapor resistant or explosion proof terminal boxes. Other flange sizes are also available.

Companion pipe assemblies are available as an optional fea- ture for some models immersion heaters

TRENT Strip Heaters are a general utility heating unit concentrating the heat where required. These heaters are designed for standard and special process machines, ovens, dryers, kettles and plastic process equipment.

CONSTRUCTION: TRENT Strip Heaters are manufactured with steel or stainless tubes without grooves to alleviate distortion when under heat. The ends are pressed tight and sealed, rendering the entire casing moisture resistant.

Terminals assemblies consist of high grade ceramic blocks with substantial bolts securely locked in position in all types except the L Series. The L Series heaters have stainless steel terminal block with mica insulation. (See illustration below).

Cartridge Type Heaters are general utility heating units that enable the concentration of heat where required. These heaters are designed for standard and special process machines, platens, glue and compound vessels, heating of valves, pipe lines, plastic forming dies, cigarette and shoe machinery.

CONSTRUCTION: TRENT Cartridge Heaters are manufactured with brass or steel sheath with end opposite terminals spun in to make a moisture-resistant heater. Silver soldered moisture proof ends are also available. A heavy duty nickel chromium coil pro- vides the heat and is inserted into a pre-formed ceramic insulator with coils running parallel to the length of the heater.

Terminals are securely anchored in the top of the heater and can be supplied in various styles to meet specific applications (See illustration below).

Equipped with threaded fit- tings, these heaters are ready for installation and use as immersion heaters with oil, water, and corrosive liquids in tanks, kettles, baths, pots or vessels of any kind. In straight lengths they are readily mounted, and do not require special machining for installation on platens, dies and extruders for conductive heating. They are also recommended in ovens with low temperature ranges requiring convection or radiant Tubular Type heating. Heaters TRENT Tubular Heaters are manufactured with a copper, steel or 304 stainless steel sheath. Type of metal used in the sheath and watts per square inch (W.P.S.I.) are determined by operating conditions. Inside the sheath is a helically coiled, nickel chromium, resistance wire heater coil that is embedded in magnesium oxide insulating material. RE The cross section design of the metal sheath assures maximum strength and R R rigidity. The tubular design also permits RE RE ready bending and forming to fit a wide RE range of applications, without damage to the heating coil or insulation material. R D

TRENT Hot Plates are heavy duty construction designed for industrial use in both production shops and laboratories. Typical applications include heating pans and vessels, dehydrating and evaporating, heat treating materials, where applic- able, sealing, and many others.

CONSTRUCTION

Each Hot Plate includes a removable 1/4” steel plate work surface, supported by a fabricated, 16- gauge carbon steel casing, which encloses the insulation and heating elements. . The heating source is a TRENT Folded and Formed® heater rack which radiates heat to the underside of the work surface. This low watts density heat source produces exceptionally long life and virtually precludes maintenance.

TRENT Hot Plates come with a standard automatic thermostatic control which operates in the range of 0° to 600°F.

TRENT Ceramic Ring Heaters have an infinite number of uses, as long as they are operated in a moisture-free environ- ment. These heaters are are commonly used as heating elements for hot plates, glue pots, molds, circular tanks, and coffee urns, among others.

The heat source for TRENT Ceramic Ring Units is a coiled, wire, resistance, heating element that is mounted in a grooved ceramic plate and embedded in cement to increase the heat transfer characteristics. Maximum operating surface temperatures range from 500° F to 1800°F, depending on how much heat is dissipated.

All sizes are supplied in single heat. Some sizes are available with low, medium and high temperature heat settings. Electrical terminations are either pigtail or stud type.
