Features and Benefits
Piping
Hydronic piping for the unit ventilator may be factory installed or field provided. It fits freely inside
the unit end pockets, supplying quick hook-up during the installing phase. The motorized valves
include a trouble-free, pop-top allowing the maintenance or service technician access to the motor
without removing the valve body from the piping package.
IAQ Features
Indoor air quality (IAQ) has become a top priority in classroom design. Giving students a healthy
place to learn and develop is crucial in every school district. It is also crucial to maintaining the
building’s overall construction and furnishings. Several features of Trane’s unit ventilator attribute
to improved IAQ.
Removable Drain Pan
The unit ventilator drain pan is dual sloped for effective condensate removal. This non-corrosive
pan eliminates the problems associated with leaking or standing water and is removable for
cleaning.
Ease of Maintenance
Internal components such as the fan and coils are accessible for visual inspection and cleaning.
Maintaining a clean system increases the efficiency of the unit and is important to good,
sustainable indoor air quality.
This design also places the coils farther away from the outside air opening, virtually eliminating the
potential for coil freezing and the added hassles of nuisance freeze-trips.
OA/RA Damper Design
The outside/return air damper is a one-piece design which is linkage free resulting in a superior air
seal (see Figure 4, p. 6). This results in lower infiltration of outside air during off cycles thus
lowering the risk of freezing equipment in the winter or the intrusion of humid air into the building
during the summer.
OA/RA Actuator
The OA/RA actuator provides true spring return operation for positive close-off of the OA/RA
damper. The spring return system of the actuator closes the outside damper if power is lost to the
building. When ordered with factory controls, the actuator is a 3-point floating design. A 2 to 10-Vdc
actuator is available when other than Trane controls are specified.
