Wattage ratings are 2.5, 5, or 10 W/in2 at 115 or 28 volts. Kapton offers a high degree of resistance to chemicals, and has excellent outgasing properties in high vacuum environments. KH models are rectangular 115 volt units; KHLV models are rectangular 28 volt units, and KHR models are round 115 volt units. Contact OMEGA sales Department for specific part numbers: 800-872-9436 Typical construction consists of an etched foil element of 0.0005" or 0.0001" thickness, which is encapsulated between two layers of 0.002" Kapton and 0.001 FEP TefIon® adhesive. Lead wires exit from the upper-right hand corner of width (W) side of heater. For 0.50" rind 1.00" wide heaters only, leads exit centrally from width (W) side. Leads exit round heaters radially. Pressure sensitive adhesive (PSA) is available as art option on heaters rated at 2.5 or 5 W/in2. The heaters can also be mechanically clamped or epoxy mounted by the user. *Kapton and Teflon are registered trademarks of DuPont. SPECIFICATIONS Heating Element Design: Operating Temperature: Voltage: Watt Density: Pressure Sensitive Adhesive (PSA): Lead Wire: Dielectric Strength: Minimum Sending Radius: Heater Thickness: Etched circuit. -328°F to 392°F (-200°C to 200°C) for heaters without pressure sensitive adhesive (PSA). Maximum operating temperature for heaters with pressure sensitive adhesive is 250°F (120°C) KH, KHR Series: 115 Volts KHLV Series: 28 Volts 2.5, 5, or 10 W/in2 Optional. not available at 10 watts/square inch watt density 12" of Teflon Insulated (MIL W-16878) lead wire (wire gauge varies with heater) 1260 Vac 0.032" 0.010" except at lead wife exit (thickness varies with heater) KH, KHR, KHLV SERIES Kapton® Flexible Heaters INSTALLATION AND OPERATION CAUTION Use a method of temperature control (e.g., thermostat, thermocouple and temperature controller, or variable voltage transformer) to prevent heaters from exceeding maximum operating temperature ratings. Place temperature sensor close enough to the heater to sense heater temperature. 1. DO NOT immerse heaters in liquids. 2. DO NOT operate heaters at a voltage higher than the specified or rated voltage. 3. DO NOT cut, punch holes in or otherwise mishandle heaters. 4. AVOID exposing heaters to chemicals, acids, alkalies. oils fluids or other substances that could ignite or cause damage to the heaters. 5. DO NOT insulate heaters unless adequate measures are taken to control heater temperature. 6. DO NOT leave heaters operating unattended unless adequate controls are installed to insure safety. 7. Heaters can be bent around curved surfaces; however, DO NOT exceed minimum banding radius. 8. Exercise care in attaching heaters to flat or curved surfaces. Heaters can be attached by mechanical clamping, by using factory applied pressure sensitive adhesive (PSA), or with a thin layer of conductive epoxy. Make sure that the entire heater is in contact with the surface with no air pockets trapped underneath. This is especially important for high watt density heaters, i.e. heaters with a watt density of 10 watts/square inch, to prevent heater failure. DO NOT overlap heaters. 9. Heaters must be attached to an appropriate heat sink and should NOT be mounted free-standing In air. 10. Make sure heaters are installed and used by qualified personnel. DO NOT attempt to repair damaged heaters.
