Section 1 Introduction The Model E4 elliptical chamber is designed for rapid heating of small size continuous materials such as tube, cable, and wire with an outer diameter from 0.25 to 0.125 inches in diameter. It may also be used as a high temperature furnace in test applications. The E4 is available in seven different lengths.
dissipates to ten percent within five seconds after power is removed. The instant on/off feature offers a great number of benefits to the user including reduced warm up and cool down times. Focused T3 lamps have a small filament, which allows the energy to be focused towards a target. By focusing the IR, the concentration of heat is greatly increased, which allows small targets to see more thermal energy and allows higher process line speeds.
Section 2 Specifications General – Refer to the table 2-1 below for general specifications and ratings on the various models of E4.

Options and Accessories Lamps Lamps for the Model E4 are included with the heater. Table 2-2 displays available lamps for replacement ordering.
Air Cooling Cooling ports provide added cooling to enhance lamp life. Four (A) or eight (AA) air-cooling ports can be provided along the length of the lamps. Clean, dry shop air should be used with the air-cooling ports. See Figure 3 for air cooling port placement.
Section 3 Safety General The E4 ChamberIR 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 that will help to prevent accident or injury.
Fire Safety 1. Obey the same fire-safety rules you observe when you work with hot plates, high intensity infrared heaters, propane or acetylene torches, soldering irons, and other equipment that operates at high temperatures. 2. Remove all solids, liquids, and gases that burn easily from the area around the heater. 3. Know where the nearest fire extinguisher is located and how to use it. 4. Know how to put out fire from all the types of material near the Model E4 Heater.
Section 4 Installation The following paragraphs describe mounting information, power connections, cooling water connections and lamp installation. Mounting Information Fasten the Model E4 to a sturdy support bracket via the 4 ¼-20NC x .37 inch deep threaded holes on the side of the reflector block. Center the unit so that specimens will be located in the focal axis. Physical dimensions for all units are listed in table 4-1, Dimensions A and B.
Power Connection Power connections to the heater are made using the attached power cord as shown in figure 41 below. Figure 4-1 Connect power according to the appropriate circuit diagram shown in figure 4-2, using the appropriate voltage rating as listed in specification table 2-1.
Cooling Water Connections 1/8” NPT tapped holes are provided for lamp reflector cooling water connections. Clean water at 100˚F maximum, less than 100 psi must be supplied to the unit, at flow rates indicated in specification table 2-1 for the appropriate sized Model E4 heater. Deionized water is preffered Connect cooling water lines to water inlet and outlet ports such that water flows thru both halves of the unit at minimum flow rates given in specification table 2-1.
5. Remove the lamp. 6. Install a new lamp and center the lamp in the heater. Wrap the lamp lead wires around the screws as shown in the picture. Tighten bus bar screws and trim off the excess wire. 7. Using a meter Ohm between the bus bar and ground checking for a short. 8. Install the lamp end covers. NOTE: Should lamp surfaces become contaminated with smoke, dust, fingerprints or other foreign material, wipe clean before continuing operation or installation Lamp Installation (E4-02, -06) 1.
5. Remove the lamp. Inspect the lamp contact points on both ends of the heater for damage. Replace as needed. 6. Install a new lamp and install the screw removed from the lamp contact in step #2. Tighten both screws. 7. Make sure the metal contacts of the lamp are in contact with the button contacts of the heater. 8.
9. Section 5 Operation General The following paragraphs describe the general principles of Infrared Heating and the detailed operation procedures for the Model E4 Quad Elliptical Heating Chamber. Principals of Infrared Heating General Heat energy from a resistance element is transformed into infrared radiant energy at the surface of the heating element. Infrared radiant energy passes through the air (without heating it) to the receiving object where it is absorbed and converted back into heat energy.
To control rapid rates in high response application a closed loop temperature controller should be used. To reduce excessive inrush current, always preheat lamp filament for at least ½ second before applying full voltage. Operating Procedures The following procedures are used to operate the Model E4 Quad Elliptical Heating chamber. Warning Prior to operation, ensure all installation procedures are performed as described in section 4, Installation 1. Unlock hinge fastener and open up unit 2.
Section 6 Maintenance Periodic inspection and removal of dirt and contaminants will ensure that equipment can be operated safely. In dirty environments or heating operations the lamps & reflectors may become contaminated with smoke, dust, fingerprints or other foreign matter. When this occurs it is recommended that the lamp be cleaned. Doing so will extend the life of the lamp and improve the heater’s overall performance.
