GECCO ventilation system

The perfect living climate

The GECCO ventilation system

The little flap with IQ

A controlled exchange between outside and inside air is a prerequisite for a pleasant room climate and greater living comfort. That is why the automatic ventilation system GECCO (GEALAN CLIMA CONTROL) is now available as an option for GEALAN windows. The little flap with IQ reliably prevents annoying draughts and mould formation in window reveals. It turns your normal windows into ventilation windows, for your own personal optimum living climate.

The flap is open in normal position, allowing air to circulate freely. The flap automatically closes the ventilation duct as wind speeds increase to prevent unpleasant draughts. GECCO works fully automatically.

The GECCO ventilation system also meets all requirements from a technical point of view. Tests have proven that this type of air exchange does not result in any significant heat losses.
