Controlled mechanical ventilation

The plant controlled mechanical ventilation (VMC) allows to check air exchange in the building, without having to open the windows and avoiding unnecessary dispersions, thanks to the heat exchanger which allows to recover the energy otherwise dispersed outside.
Machines can be of the type on time with wall or type installation centralized, with ducting and vents and / or end vents in rooms.

What is a mechanical ventilation system?

A plant controlled mechanical ventilation (CMV) allows you to control the exchange of air in the building, without having to open the windows and avoiding unnecessary heat loss.

• The stale air it is taken from the most polluted environments such as bathrooms and kitchens: before being expelled outside, it is conveyed to a heat exchanger where it preheats or pre-cools the clean air taken from outside.
• Clean air renewal it is introduced through diffusers installed in living rooms or bedrooms. 
  The VMC system ensures a continuous exchange of air, eliminates bad smells, pollutants and excess humidity, adapting the ventilation to the degree of occupation of the building.

Decentralized punctual VMC

Heat recovery of exhaust air

The heart of the system is a heat recovery (or exchanger). In it the stale air sucked in from the inside transfers heat to the clean air coming from the outside, without mixing the two flows. 

The fresh air is preheated in winter and pre-cooled in summer and at the same time filtered, guaranteeing a really healthy change of air.

The expulsion of stale air and the distribution of fresh air take place thanks to the action of a pair of fans and a network of channels.

Controlled mechanical ventilation = increased energy class

To reach the class A is indispensable break down the dispersions for ventilation by means of a controlled mechanical system with heat recovery at high efficiency.

The units ALTAIR coupled to the distribution system ensures high efficiency in the whole process of ventilation:

• High efficiency heat recovery
• Reduced electrical consumption of the fans
• Reduced head losses of all components

All this is complemented by advanced electronics that controls the flow of ventilation on indoor air quality.

Relaxation and tranquility, with VMC

The stale air is taken from the most polluted environments such as bathrooms and kitchens: before being expelled to the outside, is fed into a heat exchanger where it preheats or preraffresca clean air taken from outside.

Clean air for renewal is introduced through the speakers installed in living rooms or bedrooms.
