SRFRA/SRFGA Flexable Silicone Rubber Heaters INSTRUCTION SHEET M5719/0119 Shop online at omega.com e-mail: email@example.com For latest product manuals: omegamanual.info DESCRIPTION Silicone Rubber Fiberglass Insulated Heaters can improve heat transfer and speed warm-ups where controlled heating is required in confined areas. Two circuit designs are available: etched foil or wire wound. Heaters with etched foil designed elements are available where the length or width dimension is less than 254 mm (10"). All other heaters where both the length and the width dimensions exceed 254 mm (10") use the wire-wound element design. Effect of wattage density (at 115V): gentle warming is best done with 2.5 W/in2. A good all-purpose unit is the 5 W/in2. Rapid warm-up and high temperature are achieved with the 10 W/in2; however, temperature must be controlled as the safe maximum operating temperature limit of 232°C (450°F). Two general styles are covered in this manual. Round silicone rubber heaters and rectangular silicone rubber heaters. All part numbers and total wattage for each heater are listed in specification sheet of SRFRA/ SRFGA Series. ROUND SILICONE RUBBER HEATERS Styles are available from 3 to 12" diameters. The part number scheme is as follows: • SRFRA-[ ]/* for those heaters without the pressure sensitive adhesive. • SRFRA-[ ]/*-P for those heaters with the pressure sensitive adhesive. Where [ ] is the diameter of the heater and * is the watt density. NOTES: Heaters with pressure sensitive adhesive are not available at 10 W/in2. Maximum operating temperature is 149ºC (300º F). Examples: 6" round heater with 2.5 W/in2 wattage density, without pressure sensitive adhesive has the part number SRFRA-6/2. TM 8” round heater with 5 W/in2 wattage density, with pressure sensitive adhesive has the part number SRFRA-8/5-P. RECTANGULAR SILICONE RUBBER HEATERS Styles are available from 1" width by 1" length to 12" width by 48" length. More specifically, the length varies from the smallest width dimension increasing by 1 inch to 12", and jumps to 18", 24", 30", 36", 42", and 48". NOTES: Some sizes of heaters do not come in all lengths listed above. For details, refer to The Specification sheet of SRFRA/ SRFGA Series lists the total wattage for each heater. The part number scheme is as follows: • SRFRGA-[X) /* for those heaters without the pressure sensitive adhesive. • SRFRGA-[X] [ ]/*-P for those heaters with the pressure sensitive adhesive. where [X] is the width of the heater, [ ] is the length of the heater, and * is the watt density. NOTES: Heaters with pressure sensitive adhesive are not available at 10 W/in2. The maximum operating temperature is 149ºC (300ºF). Examples: Smallest heater 1" wide x 5" long with a wattage density of 10 W/in2 and no pressure sensitive adhesive (not available in 2.5 W/in2 or 5 W/in2) has the part number of SRFGA-105/10. 1" W x 48" L heater with 5 W/in2 wattage density with pressure sensitive adhesive has the part number of SRFG-148/5-P. 2" W x 8" L heater with 10 W/in2 wattage density without pressure sensitive adhesive has the part number of SRFG-208/10. 6" W x 42" L heater with 2.5 W/in2 wattage density with pressure sensitive adhesive has the part number of SRFGA-642/2-P. 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. D O NOT immerse heaters in liquids. 2. D O NOT operate heaters at a voltage higher than the specified or rated voltage. Heaters CAN be operated at the rated voltage of 115 VAC or lower. In order to determine the actual wattage developed at applied voltages lower than the rated voltage, use the following formula: PA= PR x VA2 VR2 where: PR = rated wattage; PA = actual wattage; VR = rated voltage and VA = actual 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 heater. 5. DO NOT insulate heaters unless adequate measures are taken to control heater temperature. 6. DO NOT leave heater operating unattended unless adequate controls are installed to insure safety. 7. Heaters can be bent around curved surfaces; however, DO NOT exceed minimum bending 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 RTV. Make sure that the entire heater is in contact with the surface with no air pockets trappedunderneath. 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. SPECIFICATIONS HEATING ELEMENT DESIGN: etched foil designed elements are available where the length or width dimension is less than 254 mm (10").
