Air Curtain LS and HS type with DX Coil

High efficiency air curtain connected to your PACi or VRF installation. EC Fan motor for a smooth operation and an efficient performance. 2 types of air flow available:

LS and HS! Easy installation, regulation, cleaning, service

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 2,5m, 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 3,0m with the LS model up to 2,7m. 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.

  • 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 systems
  • Built-in drain for cooling operation
  • HS and LS models can be controlled via Panasonic’s range of remote internet controls
The new HS and LS models are ideal for connection to a ECOi or PACi system. With simple “plug and 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.

Intelligent Operation

Our air curtains combine airflow 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.

A. Heating mode. Indoor temperature 20°C
B. Cooling mode. Indoor temperature 27°C
C. Height

Optimised airflow velocity

1. Energy losses, no air curtain installed                                          3. Optimum results with the Frico air curtain connected to Panasonic VRF
2. Too low velocity air curtain – air curtain not efficient                   4. Too high velocity air curtain – considerable turbulence, energy lost to the outside, air curtain not efficient
Opening without air curtain.
In an unprotected opening the cold air flows out and the cold storage room becomes much too warm.
Opening with air curtain, wrong angle.
If the angle is too small the hot air is blown into the cold storage room.
Opening with air curtain, too high speed.
Excessive speed creates turbulence, which causes energy loss and increases the cold storage temperature.
Opening with correctly adjusted air curtain.
With a correctly set air curtain unit there is a sharp separation between the different temperature zones.

Technical focus

  • Save up to 40% energy costs by use of the integrated EC fan technology (higher efficiency than conventional AC fan, soft start and longer motor duration)
  • 4 length of air curtain LS and HS are available 1,0, 1,5, 2,0 and 2,5m
  • Installation height up to 3,0m
  • Outlet grilles can be adjusted in five positions, to suite different indoor and installation requirements
  • Control with Panasonic remote control systems (optional)
  • Direct integration to BMS by optional Panasonic interfaces
  • Trip dray included in all DX air curtain steps


Comfort: Easy redirection of air flow by means of manual deflector.
Ease of use: Speed selector (high and low) on the unit itself.
Easy installation and maintenance: Easy installation. Compact dimensions improve installation and positioning. Easy cleaning of grid without opening of the unit.

How does it work?

Stale air from the room is taken in and ejected near the door. This creates a ‘roll of air’ that shields the door area, mixing with the colder incoming air. It then turns away from the door, back into the room and toward the intake screen, where it is partly drawn in again. This flow of air helps to create a barrier for heat loss yet at the same time refreshes room air

Maximum installation high.
HS: 3,0m
LS: 2,7m
