The WHISPER-AIR™
is a custom designed heating, ventilating, air conditioning system
that provides superior performance when compared to other such
systems in the market. A centrifugal fan wheel with airfoil design
blades is used as the primary air mover. What makes WHISPER-AIR™
distinctive is its integration of noise absorption and flow control
within the inlet and outlet of the fan. The fan noise is treated
right at the source before it discharges into the air handling
unit. As a result, the radiated noise as well as the airborne
noise at unit intake and discharge are very low. Extensive mathematical
modeling was used in the development of aerodynamically designed
inlet and outlet components to the fan in order to provide better
acoustical and energy efficient performance.
An economical and effective volume control mechanism, VAV-TROL™,
can be incorporated into the design replacing the inlet vane controls,
expensive inverter drives or other disc/cone mechanisms that are
generally used in the industry for VAV systems with centrifugal
and plenum fans. WHISPER-AIR™ is suitable for new applications,
or retrofits where high performance levels are critical, such
as hospitals, laboratories, clean rooms, arenas, pharmaceutical
plants, schools and commercial office buildings.
All WHISPER-AIR™ units are pre-assembled and factory tested
for performance, acoustics and vibration. M&I has the engineering
and design expertise to meet your most challenging requirements.
WHISPER-AIR™ is available as either indoor or outdoor installations,
and can be built in either draw-through or blow-through configuration.
Incorporating M&I WHISPER-AIR™ at the design stage of
the project can provide substantial savings in building construction
costs. Further savings are offered after installation due to increased
rentable space and reduced operating costs. All units are designed
with serviceability in mind with proper access to all system components,
facilitating easy maintenance. It can be applied to new projects
or retrofitting existing equipment.
