Section 1 Introduction The Model 4085 electric infrared spot heater (Figure 1) is designed for use in any application that requires clean, non-contact heat on a small target or object.
Heater Description Heater Module The Model 4085 incorporates an aluminum elliptical reflector polished to a specular finish. The reflector directs the infrared energy supplied by a tubular quartz infrared lamp to a spot at the ellipse focal point. Reflector Shield A reflector shield is supplied with the model 4085 to contain the infrared energy within the desired target area. Three types of reflector shields are available to accommodate a variety of heating applications.
Technical Information Product Temperatures Product temperatures to 2000°F (1093°C) can be achieved with the Infrared Spot Heater. Figure 2 illustrates the time to temperature for copper and stainless steel samples heated with a full reflector shield and without a shield. Heating rates are dependent upon the voltage applied to the lamp, the ability of the target surface to absorb radiant energy and the amount of heat loss.
Heat Flux Densities The heat flux generated at the focal point can be as high as 650 watts per square inch (101 watts per square cm) at the center of the focal point with a full shield and 335 watts per square inch (52 watts per square cm) without a shield. Heater Module The heater module is 7.22 inches (183 mm) long without a reflector shield. The reflector shield adds 4.5 inches (114 mm) to the overall length of the heater.
and approximately 8 feet (2.4 m) of cabling to allow sufficient operating space between the heater and power controller. The 5420 output can be limited from 240 to 120 volts.
Section 2 Safety General The Model 4085 Spot Heater is designed for safe operation. Nevertheless, installation, maintenance and operation of the heater can be dangerous for a careless operator or maintenance person. For your safety and the safety of others, please read the instructions in this INSTRUCTION MANUAL and follow these safety practices which will help to prevent accident or injury.
Electrical Safety There is danger of electrical shock when servicing the heater. !CAUTION! Observe that all applicable local and national electrical codes are met and a safe electrical ground system is installed before attempting to operate the heater. Refer to the Section 3 for proper installation procedures. !WARNING! ALWAYS disconnect the external power lines prior to servicing the heater. ALWAYS disconnect the power lines AND any optional interlock circuits before installing or changing lamps.
Section 3 Installation Unpack and Check for Damage Remove the Model 4085 heater from its shipping container and associated packaging. Check the entire unit for any potential damage due to shipping. In the unlikely event damage has occurred, keep all shipping containers and materials and file a damage claim with the shipping company that delivered the heater. Install Cooling Air Source Minimum cooling air at 120 SCFH must be supplied to the Model 4085 in order for the heater to operate properly.
Section 4 Operating Instructions Note: Follow all safety procedures and practices called out in Section 2 of this manual. Operating the model 4085 heater is quite simple and straight-forward once properly installed and mounted within a given application. A SCR (Silicon Controlled Rectifier) power controller is required which supplies electrical power to the heater. Typical examples of this type of power controller include the Model 5420 which can be purchased with your 4085.
Section 5 Maintenance & Troubleshooting The Model 4085 heater requires very little maintenance during its normal lifetime. The life of the heater will be prolonged as long as the proper amount of cooling air (120 SCFH) is supplied and the supply voltage to the heater does not exceed specifications. Periodic inspection and removal of dirt and contaminants will ensure that equipment can be operated safely.
6. Align the reflector shield screw holes with the corresponding holes in the heater casting. 7. Reinstall the three retaining screws into the casting and hand tighten them using a Phillips screwdriver. Model 4085 Emitter Replacement !WARNING! Remove all power from the heater BEFORE attempting to replace the Model 4085 emitter. !CAUTION! Wear soft, clean, oil-free flannel or plastic gloves when handling halogen, quartz lamps.
