Features and Benefits
The UniTrane fan-coil meets the standards of today’s market, as well as the anticipated needs of
tomorrow’s market. The tradition that company founder Reuben Trane began in the 1930s
continues with the latest generation of fan-coils from The Trane Company.
The UniTrane fan-coil is the leader in these key areas:
• Energy Efficiency
• Indoor Air Quality (IAQ)
• Controls
•Flexibility
•Quality
• Serviceability
Today’s HVAC market is concerned with issues suc
h as indoor air quality (IAQ) and CFCs that
demand a change in HVAC products. In addition, renovation has overtaken new construction in the
fan-coil market—demanding a design that caters to renovation issues. Trane is concerned with
these issues, too. That’s why we designed the UniTrane fan-coil as an integral part of the company’s
system solutions with standard IAQ-related features that fully comply with ASHRAE 62.
Energy Efficiency
Trane’s commitment to providing premium quality products has led to the exclusive use of
Electronically Commutated Motors (ECM) in all fan coil models. These brushless DC motors
incorporate the latest technology for optimized energy efficiency, acoustical abatement,
maintenance free and extended motor life. Each motor has a built-in microprocessor that allows
for programmability, soft ramp-up, better airflow control, and serial communication.
• Trane units equipped with ECMs are significantl
y more efficient than the standard Permanent
Split Capacitor (PSC) motor.
• Lower operating costs on average of 50 percent (versus a PSC motor).
• The Reduced FLA feature allows units to ship w
ith a nameplate FLA rating much lower than a
typical ECM unit.
IAQ Design
• Closed-cell insulation is standard on all units to help prevent fiberglass in the airstream.
• The main and auxiliary drain pan
s are constructed of a noncorrosive engineered plastic (ABS
and CyColac T).
• The main and auxiliary drain pans are positively slope
d in every plane to assure proper
drainage and help maximize protection from microbial growth.
• The drain pans are removable for cleaning.
• Easy filter access encourages frequent changing.
• The auto-economizer damper option
allows free cooling and ventilation to help comply with
ASHRAE 62—and save energy and operating costs.
• UniTrane fan-coils have a blow
-thru design. Low vertical units are drawthru.
Controls
• This is the industry’s first solution that is factory-mounted, -wired, and -programmed for infinite
modulation of fan speed based on space loads, using the Tracer UC400. Auto Fan Speed control
with the Tracer ZN520 ramps the fan speed up and down to meet space loads.
• All controls are factory-mounted and tested to minimize field setup and improve reliability.
• Controls are wired with a 24 Vac transformer to keep only a single source power connection
requirement to the unit.
