ELECTRIC HEATED AIR CURTAINS
electric heated air curtain
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:
electric heated air curtain
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 vanes
at outlet nozzle
for directing air
to compensate
for possible draft
conditions
through doorways.

FIRE RETARDANT AND CORROSION PROOF
Steel models are of 18 gauge paint lock metal and double
protected with gray, baked, rust preventative electrostatic
polyurethane powder coating.
NOISE LEVEL
Our air curtains operate under a low noise level in the interest
and comfort of personnel working in the immediate vicinity.

INSTALLATION INSTRUCTIONS FOR ELECTRIC HEATED
HIGH VELOCITY AND EXTRA POWER MODELS
PRELIMINARY
TO INSTALL HOUSING AND
MOTOR/FAN ASSEMBLY

1. Before removing the unit from the carton, unscrew the plastic
    nuts and remove the adjustable velocity control louver.
2. Remove the Motor/Fan Assembly from its carton. Industrial
    models have the motor/fan assembly(s) shipped separately.
    Be careful not to touch the dynamically balanced wheels or
    damage the electric heating elements when removing the motor/
    fan assembly from the box.
3. Remove the housing from the carton.
   WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC
    SHOCK OR INJURY TO PERSONS, OBSERVE THE
    FOLLOWING:

          A. Installation work or electrical wiring must be done by
               qualified person(s) in accordance with all applicable codes
                and standard, including fire-rated construction.
          B. The combustion airflow needed for safe operation of fuel
               burning equipment in the area may be affected by the
               unit's operation. Follow the heating equipment manu-
               facturer's guideline and safety standards, such as those
               published by the National Fire Protection Association
               (NFPA), the American Society of Heating, Refrigeration
               and Air Conditioning Engineers (ASHRAE) and local code
               authorities.
          C. When cutting or drilling into a wall or ceiling, be careful
               not to damage electrical wiring and other hidden utilities.

1. Measure the housing, and then center it on the wall over the
    doorway opening. See Table I for the minimum clearance required
    on the panel side of the unit for access and service.
2. Spot holes through 7/16" mounting holes. (2) on each end of the
    housing. If necessary, drill extra holes in the back of the housing
    to align with stud spacing. (See Figure 1)
3. Mount the unit with the discharge nozzle 1" above the door
    opening. If the unit is mounted higher, move it 3/8" away from
    the wall for every 1" it is moved up above the door. Any void
    between wall and unit must be sealed for optimum performance.
    Threaded rods may be used for overhead installation.
4. Use all four mounting holes when installing the housing.
5. When mounting multiple units side by side, allow no more than
    6" between the units. Master/Slave configuration required to
    allow the units to operate simultaneously. (Single T'stat Control)
    (see figure 2)
6. Replace Motor/Fan Assembly(s) in the housing and secure
    with wingnuts. Connect all motor(s) and electric heater(s)
    connections.
7. Replace the intake louver or inlet screen and fasten with the
    hex nuts.
8. Connect panel to proper voltage. Check the motor rotation.
    (See Figure 1)

FIGURE 1
ADJUSTMENTS
electric heated air curtain
1. Pull air directional vanes in air discharge nozzle to proper
    position with air flow slated slightly outward around 15°.
2. Set air velocity control louvers so that the air stream just
    reaches the floor to prevent turbulent mixing of inside and
    outside air.
3. The unit is to be installed such that the airflow is unobstructed.
4. The thermostat should be mounted such that it senses the room
    temperature. Do not mount thermostat on a cold wall, below a
    discharge grill or in direct sunlight. The high limit switches may
    trip, shutting off the heat, if improperly installed.
