Application area

Thermozone ADAC air curtain is intended 
for permanent installation above cold store 
openings with heights of up to 2.5 metres.  
ADAC is used to keep the cold in cold stores 
and allow for open cold store areas. The unit 
creates an invisible barrier that prevents 
insects, fumes, dust and smells from entering 
the area. The  ADAC units are easily linked 
to one another to cover wide openings. 
ADAC can also be mounted in false ceilings. 
Protection class: IP21

Operation

The air is drawn in at the top of the unit and 
blown out at high velocity across the doorway, 
providing a protective air shield. The air 
shield minimises cold draughts and reduces 
heat loss through open doorways. For best 
efficiency, the air curtain(s) should cover the 
whole width of the opening.

The unit can be angled and adjusted with 

the adjustment screw. The unit should 
normally be angled towards the warm side of 
the doorway. The fan speed is adjusted to the 
desired air flow (see accessory ADACR). 

The efficiency of the air curtains depends on 

how large the draught stress is on the door.  

Note! Negative pressure in the building 
considerably reduces the efficiency of the 
air curtain. Ventilation should therefore be 
balanced.

Mounting 

ADAC is positioned on the warm side of the 
doorway. The units may only be installed 
horizontally with the air stream directed 
downwards. For the protection of wider 
doorways, several units can be mounted next 
to each other. The air curtains are equipped 
with terminals for easy serial connection. 
Brackets for wall mounting are included on 
delivery. 
1. Mount the brackets on the wall. Fig. 1.
2. Mount the unit on to the brackets and 

tighten the nuts. Fig. 2.

3. Set the adjustment screw according to 

Fig. 3. The distance between bracket and 
unit should be 30 mm in the standard 

setting. 

For further details, see ”Adjustment of ADA 
Cool”. 

Connection

ADAC is equipped with cable, plug and 
socket. This facilitates installation and serial 
connection of the units. Fig. 4. To complete 
the unit a regulation and connection set 
ADACR is needed.

Accessories

The unit needs to be completed by a 
regulation and connection set  ADACR, 
consisting of a 5-stage regulator and cable. 
ADACR can regulate 7-9 units as a maximum 
(max. 7 units at 60Hz). Max. input: 5 A. 
Protection class: IP30. Fig. 4.

Safety

•  Ensure that the area around the intake and 

exhaust grille is kept free from material 
which could prevent the air to flow through 
the unit! 

Maintenance

The fan motors and the other components 
require no maintenance other than cleaning 
when necessary, recommended at least once 
year. Grille and impeller are vacuum cleaned 
or wiped clean with a damp cloth. 

The warranty is only valid if the units 
are used in accordance with the Frico 
installation and operating instructions.
