Emerson ITR manual SCR Reheat, High-Efficiency Filter, High External Static Blowers, Plenums

Optional Equipment—All Systems

10.3SCR Reheat

This reheat uses stainless steel elements and also includes the necessary sensors and controls to pro- vide variable heat output to help maintain tighter control of room conditions, especially in lightly loaded applications. (Contact factory for available voltages.) Direct expansion units only.

10.4High-Efficiency Filter

Four optional filters are available in lieu of standard package. A 4" (102mm) 20%, 30%, 40%-45% or 60%-65% filter may be specified. (Efficiency based on ASHRAE 52.1). 2" (51mm) 20% pre-filters may also be specified.

10.5High External Static Blowers

These blower/motor packages are available where external static pressures are up to 2.0 inches (500 Pa) on 60 Hz units, and up to 1.5 inches (370 Pa) on 50 Hz units. These blowers are rigidly mounted for ducting directly to the blower housing.

(Consult the factory for specific applications.)

10.6High-Efficiency Motors

These motors replace the standard efficiency motors to provide increased energy savings during oper- ation (consult factory for specific efficiencies).

10.7Plenums

Standard height of 18" (457mm) with top duct connection or two-way, three-way or 4-way grille dis- charge styles available.

Plenum With Two-Way Grille

10.8Low-Profile Plenum with Cold-Aisle Discharge

This plenum is designed to distribute supply air to electronic equipment beside and across from the cooling unit. In addition to air exiting the front of the plenum, internal baffles direct air through the left-side and right-side discharge vents. Factory-supplied hardware allows air to be blocked from exit- ing one side of the plenum, allowing the cooling unit to be installed at the end of a row of equipment.
