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.
