Water Cooling – 90° F or less cooling water is required during operation of the Model
4069. Flexible tubing and plumbing fittings are supplied with each heater for easy
installation. Required cooling-water flow rates are listed in Specifications. Chilled water
below 50° F is not required or desired due to possible condensation on reflectors.
Air Cooling – A cooling fan is designed into the Model 4069 housing and provides
ambient airflow through the heater body. This airflow helps to prevent air-borne process
gasses from depositing on the reflector surfaces. It also provides cooling to the quartz
halogen lamp end seals.
Electrical Cable – The Model 4069 heater is electrically wired from the T3 lamps to
intermediate terminal blocks within the heater. Two 12-foot (2.4 m) electrical cables are
supplied with each heater.
Split Quartz Liner – A split quartz liner is included with the Model 4069 and provides
contamination protection for the aluminum reflectors. When installed in the heater, the
quartz window protects the aluminum reflector and lamp from contaminants released in
the heating process, resulting in maximum efficiency of the heater.
Optional Power Control System – The Model 4069 can be ordered with the ‘PC’
option. An electrical junction box is included and wired directly to the Model 935
ControlIR power control box with 15 feet (4.6 m) of electrical cable. The heater is
supplied with two 12-foot (3.7 m) electrical cables and terminated with connectors that
plug into the junction box. Please see Figure 5-4, Typical Installation, as well as the
Model 935 ControlIR
