| AFX SERIES AEROFLO HEATER WHAT IS THE AEROFLO HEATER?
The Aeroflo heater is a rugged
floor-mounted industrial grade pace heater that achieves uniform building temperature,
moisture control and maximum heating efficiency using the principle of low velocity
constant air circulation to heat large air volumes to lower temperatures.
WHERE SHOULD THE AEROFLO
HEATER BE USED?
The Aeroflo heater has proven to be the
correct way to heat industrial or commercial buildings with large open spaces. The total
air circulation system provides uniform temperature throughout the space. Unit heaters,
conventional space heaters and infra-red heaters function as spot or area heaters. These
various units cannot offer the flexible building occupancy or the total space comfort of
the Aeroflo heater. It is ideal for new or renovated facilities such as large warehouses,
manufacturing plants, garages, aircraft hangars and service centers.
HOW DOES THE AEROFLO
HEATER FUNCTION?
Continuously circulating the building's
air volume several times each hour, the Aeroflo heater develops a gentle air rotation
pattern, without requiring a duct system, as illustrated in Figure 1. Cooler air at the
floor level is drawn through a screened intake in the base of the Aeroflo heater.
Specially designed twin fans direct the air upwards across the heat exchanger, thereby
heating the air. The heated air is then discharged at low velocity from the top section of
the unit through a screened hood. The air circulation continually sweeps warmer ceiling
air down to the floor level, thereby minimizing stratification. This results in minimum
temperature differentials (often 2° or less) throughout the space, assuring a uniform
comfort level. As an added benefit, the problems of condensate on equipment and materials
are considerably reduced.
For buildings requiring winter ventilation,
the Aeroflo heater can be fitted with outside air intake sections to provide a source of
heated fresh air. The Aeroflo heater can also furnish, quietly and with low power
consumption, as much as one-half of a typical building's summer ventilation requirements.
WHERE SHOULD THE AEROFLO
HEATER BE LOCATED?
The Aeroflo heater should be installed
near high infiltration or "cold spot" areas; by doorways or along cold walls.
Low pressure, created by the fans pulling air from the floor along with the returning high
volume air mass, draws infiltrated or cold air back to the return air section of the unit.
HOW DOES THE AEROFLO
HEATER SAVE ENERGY?
For several reasons, heating larger air
volumes to lower temperatures in the Aeroflo heater reduces fuel consumption in comparison
to conventional space heaters which raise smaller air volumes to higher temperatures:
Burner operation is reduced because the
high volume air circulation minimizes air stratification, thereby returning warmer air to
the heater.
The large air volume circulation also
utilizes heat recovered from internal and solar gains normally found at the upper building
levels.
Transmission heat losses are reduced
because of lower indoor-outdoor temperature differentials at the upper building levels.
Aeroflo heaters offer several additional
energy-saving features. Tandem propeller fans are used in place of conventional
centrifugal blowers to reduce motor horsepower, thereby lowering operating power costs.
Fuel consumption can be further reduced by operating the heater with night set-back and
weekend clock and temperature control. As an added economy measure, heat recovered from
complimentary equipment can be ducted into the Aeroflo discharge section. Or, preheat
steam or water coils can be fitted to the heater as components of a heat recovery system.
