QuietVent ELS in the low energy houseQuietVent ELS-VEF with automatic humidity control

Weighty advantages of theQuietVent VEF-AL system technic With this decentralized unit, the ducting system in the house or apartment can be dropped. Relevant expert opinions andpractical experiences prove thatthe ventilation heat demand inhouses or apartments can bereduced to 65% due to ahumidity controlled, mechanical ventilation. The achievments of these savings,connected with a "feel good climate in your own4 walls" and the qualitative securing of the fabric of thebuilding is a compelling result. ELS-VEF 60/30Humidity controlled waste air fan in the bathroom that guarantees a minimum air change. Turns onmaximum power when thehumidity rises and after reaching the rated value back to normal again. Combined with an overrun timer controlled QuietVent ELSin toilet. Air intake elements AL..Model ALEF.. or ZL.. for wall orwindow frame installation. Intelligence creates well-being. Steamed up mirrors are a indication of too high humidity. That means anunhealthy room climate for human beings and buildings. In a 4-person household, approx. 10-15 litres of water are created daily in the roomair. This has to be extractedthrough ventilation. To ventilate ecologically, efficiently and economically through manual window ventilation is impossible. But it’s easy with the humiditycontrolled QuietVent ELS-VEF 60 from Helios. Progressive electronics control the QuietVent ELS-VEF automatic and results in:–With normal increase of the humidity (e.g. caused by washing, drying of textiles or decrease of temperature) the fan starts automatically when the limiting value of approx. 70% relative humidity is achieved. The unit operates until the relative humidity is lowered by at least 10%.–With fast increase of the humidity (e.g. caused from showering) the microprocessorcontrolled electronic starts the fan automatically after a short time. After the comfortable zone is achieved(relative humidity of40–70%) the fan turns off automatically. These new units are head and shoulders above a conventional hygrostat function and preventssteaming up on walls, ceilingsand equipement. As a result, the QuietVent ELS-VEF 60 creates a comfortable climate without mould and annoying smells with a minimumof energy use. Control: Automatically, on the humidity levels. Typical use: For ventilation ofhumidity polluted rooms (e.g. bathrooms).
