1 General

This user’s guide is meant for the installer and for the

end user. It’s a reference to operaon and installaon of

an SR-AMC air curtain. For safety sake and to guarantee

correct operaon, it is essenalthat you read this manu-

al thoroughly before starng the installaon, including all

ps and warnings.

Keep this manual with the appliance and see to it that it is

included when the appliance is moved or

sold, to ensure that everyone is informed about the use

and safety aspects of the device throughout its

lifeme.

The Air Curtain Module consists of a metal casing with

a bladed fan and motor on top, secured by a fan guard.

There is a discharge nozzle with louvers on the opposite

side, which enables the airow to be directed in the de-

sired direcon. An air curtain consist of mulple Air Cur-

tain Modules with an assembly set.



The air curtain funcons as an invisible door/segregaon

and has insulaon properes, this can reduce energy loss-

es up to 80% with an open door. The air curtain can be

used with chilled or heated spaces. In most circumstances

an air curtain is used to minimise heat losses with an open

door, it could also be used as a segregaon between a non

or limited heated space and warmer heated space.

For example between a storage space and workshop.

The airspeed can be controlled by an oponal 5 stage

speed controller, which can be used to adjust airspeed for

dierent heights (widths), dierence in forced venlaon

(negave pressure) within the building or for variaon in

weather inuences. The switch has a stage that cuts o

power to the installaon. (stage 0).

The air curtain can be acvated through the use of a door

switch, which triggers a relay which in turn sends the

power to the air curtain.

1.3 Warranty

Operaon/installaon of appliances not according to this

manual will void the warranty. It’s not allowed to change

the specicaons or to make modicaons of any kind, on

this appliance.

2 Technical Data

2.1 Table with data

Because the SR-AMC air curtain consist of mulple modu-

lar secons, a variaon of dierent widths or heights (ver-

cal installaon) can be constructed. Theorecal there

isn’t a limit to the amount of coupled modules, but every

10 connected modules must be succoured/supported at

each end.

If more than 10 modules are used there needs to be a

another power source, because the internal

wiring is designed for a maximum amperage of 10A.

2.2 Pre-check

Before installaon, please check (i.e. on the data badge)

if the appliance is in accordance with the order and

whether it suites the local and present provisions (

electrical supply etc.). Also check aer installaon that

operaon of the appliance can’t form any hazard caused

by moisture and dust, or can cause injuries to people.

3.1 Suspension

Every unit has 4 ‘pop nuts’ at each corner, in the illus-

traon on page 3, the dimensions are depicted with the

nocaon H-H.

By using these ‘pop nuts’ one can mount the air curtain

to the wall or ceiling with brackets or M10 studs. These

are not included (as standard).

The coupled modules have to be suspended or sup-

ported at each end. The maximum non-supported or

suspended coupled units is set at 10 modules (5m) to

prevent sagging.

Each module is 500mm long. One can nd the number of

modules with resulng length in the data table on page

The air curtain has to be wider than the door opening to

provide an eecve barrier and prevent air ingress at the

ends (see Fig.2).

 Measure the width of the door in cm and

divide with 50, the resulng number is the minimum

number of modules. Almost always there is an extra

module needed for sucient overlap.



Make sure the air curtain has undisrupted ow of intake

air and blown air, there should be a minimum distance of

0.5m between ceiling or overhead door.

Horizontal mounng is preferred above vercal mount-

ing, as this enables the air curtain to also serve as a

recirculaon fan and the air stream will be warmer than

on oor level.

The side of the air stream should be as close as possi-

ble to the edge of the door opening, the further the air

curtain is placed away from the door opening the less

eecve it becomes.

The distance to the wall with our horizontal brackets is

variable between 41-368mm, with the vercal brackets

this is between 0-300mm.

The maximum mounng height is 4.5m. In case of

vercal mounng the maximum door width for one air

curtain is 4.5m. For other dimensions ask your supplier

for advice.

With use of the adjustable louvres, one can change the

direcon of the air stream, the louvres may not be set at

extreme angles, because this has a negave eect on the

eciency of the fans.

Warning: Before starng installaon make sure that

that electrical group you are working on, has been shut

o. The appliance must be earthed.

4.1 230Vac supply

The installaon must comply with all applicable local

and/or naonal standards i.e. NEN 1010.

There should be a suitable electrical group with a main

fuse. There is an electrical diagram further on in this

guide.

The electrical supply is 230Vac (50 Hz) with earth.

The appliance has to be equipped with a 230 Volt isola-

on switch or power plug. This switch should be suitable

for the maximum accumulated amperage. This switch

should disconnect phase and neutral (not earth) and

have at least an 3mm contact opening.

Switches or power plugs must be accessible at all mes.

For power supply the unit has been provided with a

3-pole power plug (female). The installer should connect

a 3-wire mains cable and a power plug to it.

With the interference of an isolaon switch or power

plug the air curtain can be connected to the mains. If the

connecon is made the fans will run connually at full

speed. See sect6.2

The air curtain can be acvated as the door opens. This

can be done with the use of a door switch, which powers

the relay of the relay box (arcle GA4100) and acvates

the air curtain. See sect6.3.

dierent heights (widths), dierence in forced venlaon

(negave pressure) within the building or for variaon

in weather inuences. Step 0 can be used to shut o the

power.

The 5-stage speed control is installed in between the

power source. Depending on the chosen stage, the fan

will turn fast or slowly.

Before installaon consult the manual of the 5-stages

switch. See sect6.2 and 6.3.

Warning: Before starng maintenance make sure that

the power group you are working on has been shut o!

The appliance should have earth!



With the 5-step switch one can adjust the airspeed on

ground level, as explained in sect4.2.

The airspeed on ground level should not be too low

otherwise the air curtain coverage cannot withstand any

wind load. Too high airspeed at ground level will lead to

unnecessary turbulence and excessive sound. The ideal

ow prole is depicted in the illustraon below (Fig. 5),

one can roughly check this by feeling with the hands, or

‘tu tesng’ with a strip of paper to visualise the airow

prole. Of course an anemometer would be best. If there

is a strong wind load on the door opening, one can turn

up the airspeed.

The air curtain isolates the interior space, thus it can be

used in summer. Not only to repel the heat , but also to

prevent the ingress of ying insects.

Aenon: Do not set the louvers in an (sloping) angle

greater than 20°. This will decrease the air output.

WARNING!

ATTENTION!

5.2 Maintenance

In spaces with heavy dust it might be necessary to clean

the fan guard with compressed air once a year. If the

fan guard is covered with severe dust the fan will have

diminished sucon capabilies.
