An industry leader since Arthur B. Modine invented and patented the first lightweight,
suspended hydronic unit heater in 1923, the Modine hydronic unit heater has proven one of
the most popular of all unit-heater types in commercial and industrial applications. Designed
for long heat-throw and uniform heat delivery, two types are offered:
• Horizontal Delivery Units (Model HSB/HC) – Recommended for use in buildings where
ceilings are low and with few obstructions. Units are normally placed around the perimeter
of the building so that the air stream from each heater “wipes” the wall to produce a blanket
of warm air along walls where heat loss is greatest.
• Power-Throw™ High Velocity Horizontal Delivery Units (Model PT/PTN) –
Recommended where there is a requirement for heat throw greater than can be provided
by standard horizontal delivery models. For hard-to-heat areas, such as frequently opened
loading dock doors or large warehouses, Power-Throw
TM
units are an ideal choice. A single
Power-Throw
TM
unit can often replace as many as three smaller horizontal delivery units,
reducing equipment, installation, and maintenance costs.
Standard features include:
• Top/bottom (Model HSB) or side (Model HC) inlet/outlet piping.
• Units install quickly, easily, and at low cost because they are lightweight, yet are ruggedly
constructed to resist rigorous handling and on-the-job abuse.
• Carefully-selected motors and fans with a scientifically designed venturi fan-shroud reduce
noise levels to a satisfactory minimum.
• Totally enclosed motor with thermal-overload protection.
• Fans are statically and dynamically balanced.
• Fan and motor assemblies are exposed and can be removed without lowering the unit heater.
• The unit casing is treated for protection against corrosion prior to the application of the
attractive gray-green, baked-on polyester powder coat paint finish.
• Horizontal air deflector blades are standard (vertical deflector blades available).
• Low outlet temperature models are recommended for steam pressure above 30 PSI, but can
also be used in dirty environments to minimize buildup of air contaminants on the coil.
• Modine PTN models feature coils made from cupro-nickel tubes that have the extra
strength to withstand higher steam pressures (250 PSI) or water temperatures (400°F).
