AIR HANDLING UNITS
Canada Blower Air Handling Units (AHU) combine a fan (or several fans)
with other components such as heating and/or cooling elements, filters,
and dampers as a means to collectively condition the air in a building.
AHU is a general term comprised of many specific types of air handlers
including: Air Make-Up Units (AMUs), Packaged Units (PU), Rooftop Units
(RTU), and Energy Recovery Units (ERU). Air handlers range from very
small, low CFM light-duty construction to very large, high CFM
heavy-duty construction, and are used in many types of buildings that
require air conditioning such as office buildings, hospitals,
universities, schools, manufacturing facilities and data centers.
Typically, air passing through an AHU is clean and varies in
temperature depending on the specific application. Energy consumption
and noise are often important considerations when selecting a fan for
an AHU. Plenum fans and DWDI fans are commonly found in these units,
but are not used exclusively. To accommodate the various applications
these units are used for, Canada Blower offers the most diverse and
efficient fans in the industry to meet the need of any air handling
unit.
AIR MAKE-UP UNITS
Canada Blower Air Make-Up Units (AMUs) are Air Handling Units that
provide 100% outside air to a building. When air is exhausted from a
building it needs to be replaced at the same rate. AMUs are designed to
replace the exhausted air with filtered outside air and often use
direct or indirect heaters to temper the air before it is supplied to
the building. Direct fired heating units are very popular, as they are
typically 20% to 40% more efficient than indirect models.
Traditionally, forward curved (FC) fans are used in AMUs, due to the
low static pressure requirements and the lower cost of these fans. As a
leading supplier of fans used in these Air Make-Up Units, Canada Blower
Fan can manufacture our products to meet our customer’s exact
specifications.
