Purge Option<br />
Purge Layout<br />
The Purge option is available on DRY-O-TRON® DS/RS<br />
models size 040 and larger. This option has all the<br />
benefits of an Economizer-type <strong>design</strong> without the disadvantages<br />
of higher initial or fan operating costs<br />
associated with Economizer <strong>design</strong>s. In fact, the Purge<br />
option also benefits from having a return air plenum. For<br />
the engineer, this means a simplified return duct <strong>design</strong>.<br />
