ALUMINUM SUPPLY TUBING
General
The Unico System aluminum supply tubing is a 2-inch (51
mm) Flexible Air Duct. It provides an insulated vapor
barrier to prevent condensation from forming on the outside
of the duct.
However, the aluminum supply tubing is not
designed to reduce the high velocity air noise. Therefore, it
is essential to use the UPC-26 sound attenuator at the end of
every branch duct to prevent unwanted noise.
The supply tubing is offered with several different choices
of insulation thickness. In most cases, the standard supply
tubing should be used. However, for extremely cold or
humid environments or where the local building code
requires a specific R-factor and the duct is installed in an
unconditioned space, use the R4, R6, or R8 products. The
R4, R6, and R8 ducts have thicker and heavier insulation
than the standard sound attenuator to reduce thermal losses.
Application
The UPC-26 sound attenuator significantly reduces sound
from the outlets. Therefore, for proper noise control, it is
recommended to use at least 3 feet (1 m) of the UPC-26
sound attenuator at the end of every two-inch branch run.
An entire branch duct can be made of one or more lengths
of the UPC-26 sound attenuator. However, because the
aluminum core tubing is stronger than the sound core, for
lengths greater than 12-feet (3.7 m) it is best to use almost
all UPC-25 aluminum supply tubing with a 3-foot (0.9 m)
length of sound attenuator at the end (Figure 1).
Where runs are required to be installed in unconditioned
spaces every attempt should be made to limit the length of
the duct run to 12-feet or less using the proper R-factor for
the application. However, as an air duct, there is no limit to
the length used other than its ability to deliver the air.
For sizing and to determine run capacity, add up all tubing
lengths in the run and use the charts or curves provided in
Bulletin 40-40, System Sizing and Layout Procedure.
Construction
The aluminum supply tubing has a 2-inch (51-mm) inside
diameter supplied in 25-foot (7.7- m) lengths and can be cut
as needed. As shown in Figure 2, the standard supply tubing
(UPC-25) is made of three layers. These layers combined
have an R factor of 3.2 °F-hr-ft2/Btu.

TOTAL AIR PROBE
AMETEK Aerospace & Defense launches a major improvement in aircraft air data sensing – the Total Air ProbeTM. The Total Air ProbeTM’s unique design (patent pending) replaces a number of traditional,
separately and redundantly installed, air data LRUs including mechanical AOAs, Total Air Temperature Sensors, Pitot Probes, and Static Air Ports. The Total Airdata Probe delivers total and static pressure in mbars, temperature in deg C, angle of attack in degrees, and BIT (built-in test) status, with one ARINC 429 connection.
The Total Air ProbeTM delivers many advantages. Combining multiple functions into one instrument saves time and expense for sensor installation. Since connectors are a historical weak point for instrument reliability, the Total Air Probe provides increased reliability due to a reduced number of connectors vs traditional methods for Air Data Systems. Further, the unit contains heater power control for better heating efficiency and increased reliability due to lower duty cycle.
The Total Air ProbeTMcontains highly accurate, highly reliable air data pressure sensors within its housing. By locating the pressure sensors closer to the measurand, the readings are more accurate than those provided by systems with remotely located pressure sensors that add pneumatic pressure delays.
The result is a more accurate reading for altitude. The pressure sensors are also utilized in monitoring angle of attack, or angle of side slip, depending on location of the unit’s pressure ports relative to air flow.
AMETEK Aerospace & Defense has a reputation for supplying innovative products for the aviation and military industry. The Total Air ProbeTM builds on AMETEK’s experience with Total Temperature Sensors for aircraft engines, a critical instrument operating in a difficult environment. It also capitalizes on over thirty years of experience with aircraft Angle of Attack Sensors and Stall Protection computers.
The result is a reliable sensor that offers a number of advantages for aircraft air data systems.

UPC-101 SLOTTED OUTLET PLENUM KIT
Application
The Unico System UPC-101 slotted takeoffs are specially designed to
deliver air directly from the main plenum into a room. It is very useful
if there is no space to run supply tubing and
the plenum is covered by a
soffit, or when exposed ductwork is utilized. It comes standard with a
white rectangular plastic trim plate with a slotted opening for the
nozzle portion of the outlet. The trim plate is the only part that is seen
in the occupied space, and can be painted to match any decor.
General
The Unico System slotted takeoff is made of galvanized sheet metal
and is designed to fit the trimplate. The takeoff is designed for either a
round or square 1-inch (25-mm) fiberglass main plenum. It is not
intended for metal ductwork.
NOTE: The main plenum must have an acoustical lining for proper
sound attenuation.
Always use at least 6 outlets per ton with a maximum of 35 CFM per
outlet. For the best sound properties, design for 30 CFM per.
For wall installations the UPC-101 should be located high on the wall
and a minimum of 5-inch (13-cm) below the ceiling. For ceiling
installations locate it a minimum of 4-inches (10-cm) away from the
adjacent wall.
The airflow can be checked with a TurboMeter positioned at the center
of the outlet. Using the knots reading multiply the value by 4, then
add 4. For example, if the TurboMeter indicates 7 knots, this would be
(7×4) + 4 = 32 CFM.
