Perdea de aer in recirculare cu montaj orizontal/vertical FRICO PA4220A L=2 ml

Air curtains do not produce hot air during recirculation.

Thirty years of air curtain development in the demanding Scandinavian climate has given FRICO a unique platform to create air curtains with optimal door protection by using Thermozone technology.
Thermozone air curtains are optimized in:

- airflow geometry;
- performance;
- level of noise.

Airflow geometry:
Air curtains were developed so as to obtain low sound level and turbulence, without influencing the efficiency.

Performance:
There is a balance between air volume and its speed, which leads to optimum efficiency.
It is considered the fact that the high air speed generates high turbulence and air noise, and the air volumes require high heating power.

Level of noise:
FRICO mainly focuses on the level of noise and constantly works to improve it, the type of ventilation used and the optimization of noise.
The level of noise is an environmental factor at least as important as light, fresh air and ergonomics.
Attention given to low noise level is getting higher.

Thanks to air curtains, both in summer and winter, a real barrier, that prevents effectively the cold air from penetrating the room, is formed.
Meanwhile, the air curtains prevent penetration into rooms of various pollutants, dust and insects.

FRICO PA4220A air curtain is supplied with smart control and is ideal for all rooms with heavy traffic such as offices, restaurants, hotels, and industrial areas, also offer the possibility to install both horizontally and vertically (valid for air curtains with length greater than 1.5 m).

FRICO PA4220A is prepared for the SIRe control system whose pre-programmed default settings and many features make it easy to install and use the air curtain.

HOW TO CHOOSE THE SUITABLE AIR CURTAIN:
- the entire length of the opening should be covered;
- the air flow should be sufficient for the opening height. Door loading in different windy or pressure conditions, the frequency of door traffic should also be considered;
- a balanced ventilation is essential;
- the air curtains cannot prevent excessive currents or strong winds.
