A guide for your construction project
from Systemair
Did you know, that by insulating the building shell – and particularly by replacing windows and doors – the natural exchange of air is often reduced by up to 40 times? This means the risk of mould formation, dust mites and stale air in general also increases considerably. The right solution: a ventilation system with heat recovery.

It's smart to use fresh room air to save energy at the same time – via heat recovery. Systemair equipment also offers decisive advantages over pure extraction systems and is available with either rotary or counter flow heat exchangers.
In a rotary heat exchanger, heat from the extract air is used to warm the incoming cool supply air, and to transfer some of the moisture content to the supply air. This enables your customers to achieve up to 85 % heat recovery efficiency. Only a counter flow heat exchanger can offer more, with up to 90 %.
