ELECTRIC
HEATED AIR CURTAINS

|
Q
|
The first question is, do I really
need a heated
air curtain? |
|
A |
The answer is maybe not. Air doors
effectively
create an efficient insulation barrier between
two environments. It's approximately 80% -
90% efficient. It does so by creating a stiff
blast of air blowing down from the unit towards
the floor. This blast of air create an invisible
barrier separating the two environments.
If you have people working near or walking
through this moving air, they may feel a breeze.
This could cause a wind chill effect, similar
to
the cooling effects of a blowing fan during the
summer. Adding a heated air curtain unit will
minimize this effect and make for a comfortable
and more productive work place for your
employees and customers.
Should your facility be located in a cold weather
environment creating significant temperature
differences between the outside versus the
inside temperature, a heated unit will signi-
ficantly improve the work environment comfort
level and help maintain consistent temperature
control. In addition, it will reduce overall utility
and maintenance costs by providing a more
constant inside temperature. |

|
| TYPICAL
USES |
|
|
|
|
|
Easily
mounted over entrance ways of warehouse
doors up to 16 feet high, the air curtains direct an
invisible stream of stratified heated air downward.
In
addition to adding to employee and customer comfort
during cold weather they provide important energy
savings in three ways: |
|
|
|
|
|
|
|
|
|
|
|
 |
|
|
|
|
|
|
1.
In cold weather they reduce the load on heating
systems. By drawing warm air down to floor level
where it is needed, our air curtains utilize the 50%
of wasted heated air trapped under ceilings. Stratified
air is mixed and circulated with building heat and heat
given off by lights and machinery, etc. |
|
|
|
|
|
|
|
|
| ENERGY |
|
|
|
Our
air curtains conserve energy and improve comfort by
limiting the escape of internal heat, reducing cold
drafts
and providing a welcoming down flow curtain of warm
air at entrance ways in industrial plants and store
buildings.
The resulting mixture of warmed air disperses gently
in all
directions at floor level to give uniform temperature
over
a wide area from floor to ceiling with only a few degrees
difference. |
|
2.
The high velocity curtain of air deflects winds and
reduces excessive heat loss through open doorways. |
|
|
|
|
3.
During warm weather they can direct a stream of air
downward to help keep dust, dirt, insects and fumes
from
entering through open doorways. If air conditioning
exists
in the building during warm weather, the air curtains
can
be used to prevent loss of conditioned air as well. |
|
|
|
|
|
|
|
|
|
|
|
|
|
| CONVENIENCE |
|
|
|
|
|
|
|
|
Our
air curtains allow personnel and cargo to pass freely
from one area to another while maintaining desired
temperatures. |
|
An
added safety feature is the free flow of traffic with
an
unobstructed view through the opening, eliminating
doorway accidents. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Our
air curtains create an invisible barrier of high velocity
air
to stop cold or warm air infiltrating plant facilities
and work
areas. |
|
Stop entry of cold or warm air when doors are open. |
|
Prevent the possibility of accidents with unobstructed
view of passageways. |
IMPORTANT:
MUST BE INSTALLED ON WARM
SIDE OF DOORWAY OPENING WHEN USED FOR
TEMPERATURE CONTROL |
|
Eliminate need for expensive plastic stripping, flapper
doors, or canvas curtains. |
|
Cold
weather can be further deterred at door opening if
space heater in plant is directed toward intake of the
air
curtain. |

| SPECIFICATIONS
AND FEATURES |
|
|
|
|
|
| FOR
ARCHITECTS AND ENGINEERS |
|
EASY
INSTALLATION |
Our
air curtains shall have a self-contained one piece
housing, fire retardant and corrosion proof, incorporated
with
a double extended shaft motor, direct drive double width
and
double inlet squirrel cage blower wheels and fan housings. |
|
Our
air curtains are bolted to wall with four fasteners
and
connected to electric power source. |
|
AIR
VELOCITY CONTROL FOR VARIABLE AIR
SPEED |
Shall
have wedge shaped discharge nozzle containing
adjustable air deflectors with 40% sweep front to back. |
|
Adjustable
louver damper controls are provided in order to
adjust rate of air flow. |
Housing
shall be sufficient strength for fastening to wall on
both ends without any intermediate support. |
|
When
used over a doorway to retain warm or cold
temperature, proper velocity adjustment is imperative
for
maximum efficiency. Velocity Control can reduce air
velocity
up to 60% with louvers in totally closed position. |
| HEAVY
DUTY ELECTRIC MOTOR |
|
Continuous
duty type motor with double sealed lifetime pre-
lubricated stainless steel ball bearings, resilient
mounted and
protected by an automatic thermal overload switch.
Underwriters Laboratories Listed and Canadian Standards
Association Certified. Explosion proof motors available. |
|
|
AIR
DIRECTIONAL CONTROL |
|
Adjustable
