What You Need to Know before Buying an Air Curtain
Guide - Air Curtains
Air curtains create an air barrier between hot and cold, both to prevent cold outdoor air from entering, while the heated air is kept inside, and to protect air conditioned premises and refrigerated rooms. A correctly installed air curtain reduces draughts, creates a comfortable indoor environment and reduces energy losses at doors and doorways.
Choose the Right Air Curtain
For optimal air curtain effect, it is important to choose the right air curtain. We have air curtains for all openings from small kiosk hatches to large industrial doors. They blow from above, from the side or from below. Choose between electrical, water heated or unheated versions.

To Get the Most out of the Product, the Following Hints Are Important to Bear in Mind
To ensure that the air flow reaches the floor at the optimal air speed, the installation height (not the height of the opening) determines the choice of air curtain.
The air curtain units should cover the whole width (or height) of the opening. The air curtains can be obtained in different lengths. For wide (high) openings, several units are mounted beside (on top) of each other.
The units should be positioned as close to the opening as possible.
For optimal performance it is important that the pressure difference between outside and inside is not too big.
Independent tests show that a correctly installed air curtain can reduce energy losses at an open door by up to 80%.
)
If you choose an air curtain based purely on air volume you may get an air curtain that only gives good protection close to the outlet, where the impact on the door opening is less.
)
By setting requirements for the air velocity and uniformity of the air beam at floor level, you have an air curtain that covers the whole door opening.
Building Structure
Before installation, it is important to study the structure and ventilation of the building, taking into consideration draughts, likely wind loads and artificial pressure. Balanced ventilation is essential.
If you have a draught problem, the general rule is to choose an air curtain with heat.
Ambient air curtains without heat are recommended for use in cold storage openings and air conditioned premises in warm climates.
For cold climates, the air curtain with heat may be used with only the fan function during the summer to keep the air conditioned air inside.

Intelligent Regulation
How efficient an air curtain is and how much energy can be saved depends to a large part on the control system. Many factors that affect the air curtain vary over time. The variations can be long term, for example seasonal, or more temporary, for example when the sun goes behind clouds, the premises fills with people or when a door is opened.
FC Control system helps to create many smart and energy saving features. In addition to our four packages, components can be added to expand and customize the system.
