KWL® from Helios. Energy saving for a healthy climate. Today more important than ever. The political measures set for the global climate will affect the construction industry over the next few years. The main aim is to reduce the amount of greenhouse gases by 40 % before the year 2020. In these circumstances the demand for energy efficiency standards, for the establishment and renewal of buildings, increases further. Improved energy efficiency leads to an airtight building shell. The higher efficiency requirements become apparent in the European and national legislation. Already the...

KWL® from Helios. Healthy, comfortable climate ... and you feel good. The ventilation concept with added value. A KWL®-unit from Helios for controlled ventilation with heat recovery guarantees the moisture protection according to DIN 1946-6, completely, permanently and independently of user behaviour. Beyond that the necessary minimum air exchange is automatically ensured round the clock. Research proves that people living or working in inadequately ventilated buildings suffer from many ailments such as headache and allergies. On average, humans spend 90 % of their lifes in closed...
