DESIGN BENEFITS
Application, Design, Construction Overview - All Units
Wide Product Selection
Ratings as low as 11,300 Btu/hr for hot water to as high as 952,000 Btu/hr for steam, based on standard conditions.
Horizontal, Vertical, and Power-Throw™ (high velocity horizontal air delivery) models offer maximum application flexibility.
Ratings are shown as Btu/hr (based on 2 PSI steam, 60°F entering air conditions), eliminating the need to convert from EDR.
This simplifies the matching of unit ratings to building heat loss.
Application Flexibility
Horizontal and Power-Throw™ units are furnished with louvers for directional control of heated air. Vertical units are available
with various louver, truncone, and cone-jet deflector options to accommodate many different air distribution patterns. See
page 22 for more information.
Units are available as low outlet temperature (LOT) models. LOT models have coils with fewer fins per inch to reduce the
output rating. This is a benefit for applications where the steam pressure exceeds 30 PSI and mounting height is critical; the
lower output results in outlet air temperatures that approximate that of standard coils at standard steam pressure. LOT models
are also well suited for dirty environments where the increased fin spacing decreases the build-up of foreign particles. Finally,
LOT models offer lower airside resistance resulting in greater allowable mounting heights and greater heat throw.
Vertical and Power-Throw™ units are available with 90/10 cupro-nickel coils for high pressure/temperature applications, up to
250 PSI or 400°F.
• Side piping connections on the HC/HCH horizontal air delivery model allow for low clearance installations.
• Explosion-proof motors are available for use in hazardous areas. See page 8 for additional details.
Design assures the correct relationship between air temperature, velocity, and air volume for greater heat throw; air is delivered
to the floor at maximum mounting height, increasing comfort and reducing fuel costs.
Ease of Installation/Maintenance = Reliability
• Units are compact and lightweight, requiring fewer contractor hours to install.
All units include an electrical junction box, either integral to the motor or mounted on the unit casing, to allow for easy electrical
connections.
All motors are totally enclosed. All single phase and explosion-proof motors include internal overload protection to protect the
motor from insulation damaging heat, resulting in longer motor life.
• Different suspension options are available for most units including threaded rod or pipe hanger adapters.
All units are component tested for proper motor function and the coils are leak tested under pressure to ensure proper function
when the unit arrives at the jobsite.
Fins on all units are vertical to limit build-up of foreign particles, prolonging periods between cleanings. Fins on vertical and
Power-Throw™ units are exposed for easy cleaning.
Blends with the Environment
• Quiet operation is assured through the use of carefully selected motors, fans, and scientifically designed venturi fan shrouds.
HSB/HC/HCHC models have squared off corners for a clean, defined appearance. Vertical and Power-Throw™ units have a
pleasing circular symmetry.
Casings are treated for corrosion resistance and finished with a neutral gray-green baked-on, electrostatically applied polyester
powder coat paint finish.
HCH Casings are treated for corrosion resistance and finished with a Hammertone Beige baked-on, electrostatically applied
polyester powder coat paint finish.
