Conrad heated hose is a custom designed and manufactured product incorporating time-proven materials throughout. Heated hoses are available in a wide selection of hose core inner diameters and in any desired length from 10 inches to over 140 feet long. The hose inner core is comprised of extruded PTFE or PFA Teflon®, 0.030" or 0.040" wall thickness, which offers exceptional resistance to temperature cycling and kinking. For those applications requiring exposure to temperatures in excess of 400°F (204°C), hoses are furnished with an all metal, corrugated inner core and a high temperature 700°F (400°C) resilient fiberglass heater and insulation. Additional specifications for Conrad Series CH92 high temperature hoses are available from the factory. The hose reinforcement is provided by one or multiple layers of braided type 304 Stainless Steel wire. Nominal pressure ratings are 25% of the demonstrated burst pressure. The hose end fittings are a progressive swage or crimp design and are available in Stainless Steel, Brass, or Aluminum. Choose between a Female and Male NPT, Female and Male 37o JIC Swivel, Tube stub, Cam and Groove, Sanitary Flange, BSPP and Metric or many other end fitting options. The Conrad Multi-strand heating element is comprised of a strong nickel alloy utilizing multiple end, fine gauge wire stranded design for maximum resistance to flexing while offering a large heated surface area (95%) for optimal heat transfer compared to single conductor types of heating elements. Individual strand bundles are fixed in place and insulated with flexible, high-temperature fiberglass. A layer of silicone rubber serves as an elastic cushion as well as a dielectric insulator to isolate the abrasive effects of the hose core braid. Hose thermal insulation is provided by multiple layers of a high quality and nonflammable material which incorporates excellent temperature resistance, flexibility, and light weight while maintaining a cool running outer surface. The outer cover of tough polyester braided jacketing serves to protect the hose, insulation, and internal components while presenting an attractive finished appearance. Other options are available, including an extruded silicone covering for water-protection as well as a variety of wire reinforced, flexible materials. The hose ends are finished with a hardened tight fitting molded cover of Polyolefin. All integral components are bonded together within the assembly and to the hose core to prevent chemical or flexible damage and separation in use. Heated hose electrical characteristics will match any requirement of voltage, phase and power needed. A variety of wiring options, temperature sensors, temperature controllers, and temperature control methods are available to match most requirements. Typical Heated Hose applications include: Packaging Industry Photographic Development Solutions Paper Mills Corrugated Cardboard Lamination Automobile Manufacturing Chemical Transfer Automobile Emissions Testing Plastic and Rubber Extrusion Laminated Glass Manufacturing Two Part Foam Transfer and Application Food Transfer (FDA approved)
CONSTRUCTION The drum heater heating element utilizes a multiple strand, fine gauge Nickel alloy wire for maximum flexing resistance and efficient heat dissipation. It is enclosed in a two ply combination of silicone rubber impregnated fiberglass fabric which yields excellent moisture and chemical resistance. The unique attaching method effectively maintains the heater in close contact with the drum for quick heat transfer while allowing for variations in drum diameter. A silicone covered power cord insures maximum strain relief and maintains the moisture barrier at the cordheater junction. 120 volt units are furnished with a 3-prong parallel blade plug. 240 volt units are furnished with a 3-prong tandem blade (NEMA 6-15P) plug. An optional adjustable thermostat is mounted on the heating element giving excellent control of heater temperatures for those applications requiring this feature.
Heated Lines - The longest and most reliable in the industry. Conrad Heated Emission Lines are the perfect addition to your emissions testing laboratory. Replaceable Inner Core Heated Lines - Our field recoreable model facilitates the changing of the Teflon inner core, which greatly improves the overall life expectancy of the heated line. Should the line kink, perforate, or degrade through prolonged testing, a five minute changeover period is all that is necessary to completely replace the inner core. No special tools and no mess involved. This time saving method directly translates into a cost-effective solution for your organization. Units can be equipped with an auto-reset over temperature thermostat to provide safety an to prevent unintentional damage from excessively high temperatures. Standard voltages are 110 and 220 VAC, however the lines can be manufactured in any voltage from 12 VDC to 600 VAC. The lines can be ordered in any length from 1 foot to 150 feet long, therefore insuring a custom and proper fit into your particular environment and test cell laboratory.
CONSTRUCTION: Heating Element is a fine gauge, multiple stranded, stress relieved wire insulated with fiberglass yarn and secured to the heating face. Element construction of up to 150 feet of stranded wire per square foot of surface eliminates hot spots and insures fast heat up time and long service life. Heating Face and Cover are fiberglass fabric woven of “itch-proof” Beta glass high temperature yarns. Thermal Insulation is a fiberglass felted wool. One inch thick is standard. Seam Closure provided by nickel plated lacing hoods is standard. Eyelets, Velcro ™ tape, and lacing ties are also available. Power Leadwires are a high temperature fiberglass insulated nickel plated copper
SILICONE RUBBER: Two layers of silicone rubber impregnated fiberglass are vulcanized together and enclose the multiple strand wire resulting in a rugged yet flexible sheath with excellent moisture, chemical & wear resistance FIBERGLASS: The multiple strand, fine gauge resistance wire is enclosed in four layers of braided fiberglass high temperature yarn. It is then knitted into a flat tape insuring a high degree of flexibility while maintaining the unique wire arrangement.
Custom manufactured temperature controllers are available for any application that requires tightly controlled or monitored temperatures. We offer standard configurations able to control loads up to 3000 watts, and utilizing either Type J thermocouples or RTD sensors. Temperature Controllers that can handle higher wattage loads or different sensor types are also available. We can provide a Temperature Controller for any application you may have.
