Lamps for the Model E4 are included with the heater. Table 2-2 displays available lamps for
replacement ordering.
(*) Standard lamp that ships in heater
(**) Lamps are for Horizontal Operation Only
Quartz Liner -
A quartz liner can be provided to protect the reflectors in the heater from contaminants, to
maintain the reflectors at their maximum efficiency. It has a 2.24 inch (57 mm) outer diameter
and a 2.09 inch (53 mm) inner diameter.
Observation Window -
A 0.5 inch diameter window (W) with a quartz cover can be provided in the center of the
chamber side wall, to permit product viewing. With the quartz cover removed, product
temperature can be measured with a suitable optical pyrometer. The observation window is not
available on models ordered with four purging ports. See Figure 3 for Window placement.
Purging Ports -
Purging ports can be provided on two (P) or four (PP) opposing sides of the chamber wall. This
feature allows the heating environment to be force-cooled or inert gas-purged. Purging ports
will not function with a quartz liner installed. See Figure 3 for purge port placement.
