System

Airing

Ventilating

Air-air exchanger

Natural convection causes the temperature

to drop inside the enclosure. Simple

solutions for this case include installing

grilles (without filter) or lifting the top.

Fans with filters are designed to evacuate

a large amount of heat economically.

Air-air exchangers are equipped with

an aluminium exchange cassette which

separates the internal and external air

circuits and prevents the entry of dust.

When should it be used? This solution can only be used when the

power to be dissipated is low, in an

environment with small amounts of dust.

When larger amounts of heat need to be

evacuated in a polluted environment.

The air-air exchangers are used in highly

polluted environments or when it is

necessary to evacuate large amounts of

heat while guaranteeing the independence

of the internal and external air circuits.

It is important to have a difference of

temperature of at least 10°C.
