Electric air curtain with DX coil
Designed to improve energy efficiency, minimise heat loss from
a building, and allow retailers to keep doors open to encourage
customers, our air curtains are suitable for connection to both
PACi NX and VRF Systems.
Highly efficient heating effect
The combined air stream, which has a desirable low air
current induction factor (mixing factor), can carry the
selected initial temperature effect over long distances, and
will reach the floor area while still at room temperature.
This is necessary to avoid cooling down the interior
spaces.
Available in different lengths to suit requirements between
1 and 2,5 m, both air curtains have outlet grilles that can
be adjusted to five different positions. The HS model can
be installed up to a height of 3,0 m with the LS model up
to 2,7 m. The outlet grilles can be easily adjusted into five
positions to suit different installation requirements and
the air filter can be accessed without the need for
specialist tools.
Heating capacity comparison: Electrical air curtain / Panasonic air curtain.
· High performance with EC fan motor (40% lower running
costs compared to a standard AC fan motor)
· Easy Cleaning and Servicing
· Can be connected to either Panasonic VRF or PACi NX
systems
· Drain pump for cooling operation optional
· HS and LS models can be controlled via Panasonic’s
range of remote internet controls
The HS and LS models are ideal for connection to a ECOi
or PACi NX system. With simple “Plug & Play” installation,
both are fitted with an EC fan motor for a smooth
operation and efficient performance. This fan guarantees
40% lower running cost than with a standard AC fan
motor. Air curtains run approximately 12 hours per day at
shops, and efficient performance contributes to energy
savings.

Opening without air curtain.
In an unprotected opening the cold air flows
out and the cold storage room becomes
much too warm.
3 | Too high velocity air curtain – considerable turbulence,
energy lost to the outside, air curtain not efficient
4 | Optimum results with the Frico air curtain connected to
Panasonic VRF

Opening with air curtain, wrong angle.
If the angle is too small the hot air is blown
into the cold storage room.
Intelligent operation
Our air curtains combine air flow and heating / cooling
technology to ensure optimum comfort and energy
efficiency whilst also creating an effective barrier between
indoor and outdoor environments. Design and installation
is key to achieving the correct height / temperature
settings to achieve optimum performance. Our air curtains
are designed to answer the demands of the retail,
commercial and industrial markets.

Panasonic air curtain
* With the U-100PZH2E5 on the
PAW-20PAIRC-LS.
Calculation method: Taking
as consideration SCOP of the
Panasonic combination of 6,0.
If 100 is the energy needed
for a air curtain, Panasonic
air curtain will need 1/
(1-6)*100=20.

Opening with air curtain, too high speed.
Excessive speed creates turbulence, which
causes energy loss and increases the cold
