Energy-Saving Warehouse
Ventilation Year-Round
Warehouse ventilation presents
unique challenges. Greenheck's
complete line of ventilation products
work together to maximize energy
effi ciency, minimize initial equipment
cost, reduce installation time and
cost, and protect inventory and
packaging integrity in warehouses
and distribution centers. No matter
the season, Greenheck can provide
the solution to meet your warehouse
ventilation needs.
SUMMER VENTILATION
Warehouses and distribution centers
commonly use high amounts of
outside air in the summer months
to keep the space cool and
comfortable. These systems remove
hot air from the building and replace
it with fresh outdoor air one to three
times per hour. Outdoor air enters
through intake louvers, circulates
through the building, and is pulled
out through axial exhaust fans.
Greenheck operable intake louvers
are designed to provide high amounts
of free area that minimizes pressure
drop resulting in fan operation
cost savings. Greenheck's high
effi ciency roof-mounted, sidewall
or hooded axial exhaust fans with
energy-saving motor options further
reduce operating costs and meet any
application need.
SPACE HEATING
The minimum ventilation
requirement for warehouses,
0.06 cfm/ft2 per the
International Mechanical
Code and ASHRAE 62.1,
may seem insignifi cant,
but the amount of energy
to heat the ventilated air
to the space temperature
can be 20% to 30% of the
overall heating load for a
typical warehouse. Direct gas-fi red
equipment delivers this needed
outside air to the space more cost
effectively than other technologies,
while also effi ciently heating the
warehouse. Direct gas-fi red make-up
air units provide highly effi cient
heating by utilizing 100% outside air
and 80/20 recirculating confi gurations.
Greenheck's direct gas-fi red make-up
air model DGX is available with a
direct drive mixed fl ow fan that can
reduce operating power by as much
as 50% at a similar fi rst cost.
system year-round. During the
summer months, HVLS fans provide
a gentle breeze, creating a cooling
effect to make the space feel
cooler. When used in the winter,
these fans destratify thermal layers,
effectively mixing the warm and
cool air and evenly distributing the
heat throughout the space. The
improved air circulation also aids
with condensation prevention,
helping to maintain dry fl oors and
surfaces for a safer work environment.
AMCA Certifi ed for Circulating Fan
Performance, Greenheck HVLS fan
models DS-3 and DS-6
offer capacities up to
243,000 cfm and can
reduce HVAC costs by
up to 30% annually
