Components - Titan TA-109 Operating And Service Manual

COMPONENTS

BLOWERS
The typical blower(s) used in Titan Air equipment are AMCA rated industrial type forward curve
D.W.D.I. fans. Backward incline, backward airfoil, and plenum/plug fans are used occasionally.
Models TA-109 through TA-136 utilize a single blower while models TA-215 through TA-242 utilize
twin blowers. All blower wheels are mounted on a solid, turned, ground and polished shaft. 9" and
12" blowers are supported with permanently lubricated ball bearings. Larger blowers are supported
by relubricatable pillow block ball bearings.
MOTOR & DRIVE
Open drip proof (ODP), rigid base, single speed (1750 rpm) motors mounted on an adjustable
base are standard equipment. TEFC, high efficiency, two speed, and other motor options are
available. High quality motor starters and electronic overloads with phase loss protection are also
standard items.
V-Belt drive assemblies are selected with a 1.5 service factor. Equipment furnished with a
supply VFD will typically have a fixed motor sheave. However, some equipment may still utilize a
variable pitch motor sheave on motors up to 30 Hp.
INDIRECT FIRED HEATING
BURNER INFORMATION
Titan Air Handlers can be equipped with inshot style burners and heat exchangers or power
burners with drum and tube heat exchangers. Both styles of burners and heat exchangers are ETL
labeled for indoor and outdoor use. Additional information regarding the indirect fired heating section
is included. All equipment with power burners require burner manufacturer trained personnel to
perform start up and service.
ELECTRIC /ELECTRONIC CONTROLS
Typically, equipment are equipped with a motor starter and overload, control power transformer
(if a 3-wire system), and remote control panel. Discharge or space temperature controls may be
provided by Titan Air or may be field supplied. Electric coil heating equipment will be equipped with
an airflow switch and temperature limits by the electric duct heater manufacturer.
Numerous standard control packages are available and optional items can be added to these
packages. For more information regarding these options, refer to catalog data or contact a local
Titan Air Representative.
