new ranges of fans for demand controlled ventilation

two new ranges ventilation of collective fans for demand controlled VCZ and VTZ fans are designed for installation of collective mechanical ventilation in dwellings or in tertiary buildings. They can be installed on terrace or roof (VTZ range), or in the attic (VCZ range). With airflow ranging from 500 m3/h up to 2.750 m3/h, VCZ and VTZ fans can be used in buildings of different sizes to serve up to 20 or 30 apartments, depending on their type. Numerous adaptation parts allow installation on various configurations of duct, chimneys and roofs. Their integrated pressure control device makes...

Demand controlled ventilation, the best way to balance indoor air quality and energy savings The concept of demand controlled ventilation rests on the principle of providing occupants with the right amount of fresh air, when they need it, where this is useful. With intelligent airflow management, energy savings are made on every occasion that the need for ventilation is low or null, which can represent more than half the time. Conversely, an activity which emits indoor air pollution such as preparation in a kitchen, a shower, or even the release of odorous metabolic compounds, generate a...

Increased life of fans By reducing average airflow over the year, demand controlled ventilation permits a reduction of the demands placed on the fan, and thereby increases its longevity: the latter depends in particular upon the power at which it works, and that power is directly related to the request of average airflow through the ventilation system. Greater availability of pressure and airflow for terminals In a collective ductwork system, serving either an individual home or collective dwellings, the airflow modulation at the various terminals permits the avoidance of overloading the...

An easy and rational system The Aereco’s mechanical ventilation (MEV) with demand controlled airflows implements three types of components: extract units (1), air inlets (2) and one or several fans (3). The latter is located on the roof (VTZ) or in the attic (VCZ). The air is exhausted through the extract units located in wet rooms (kitchen, bathroon, WC). Humidity sensitive or with presence detection, they allow to dispatch the airflow according to the needs. For their part, humidity sensitive air inlets balance the fresh air according to the needs of each main rooms (bedrooms and living...

Collective fans for terrace or pitched roof Solidity and performance for collective installations VTZ fans range proposes four models with capacities going from 500 m3/h up to 2.750 m3/h for the equipment of collective dwellings, offices, schools or other buildings. VTZ fans are designed for an outdoor installation, in terrace or on a pitched roof. Many connecting parts are available to adapt to different encountered cases. VTZ fans are characterized by their solidity and by an excellent energy efficiency, thanks to the use of high-performance electronic commutation motors and to an...

Electronic commutation motor for a minimal consumption The electronic commutation motor of the VTZ roof exhaust fan offers an optimum consumption all the time. Associated to the pressure control device, it automatically adjusts the consumed power to the requested airflow, while maintaining a constant pressure. The motor integrates an electric switch of in case of high temperature and an output which can be use to diagnose a possible default. Pressure control device A system of pressure control is integrated to the fan, allowing to define easily the pressure at working. Pressure measured by...

Collective fans for attics VCZ attic exhaust fans offer four models with capacities from 500 m3/h up to 2.660 m3/h for the equipment of collective dwellings, offices, schools or other types of buildings. VCZ fans are designed for an installation in attics, on the floor, on the wall or fixed to a beam. They are characterized by their solidity and by an excellent energy efficiency, thanks to the use of high-performance electronic commutation motors and to an integrated pressure control device. 4 models of fans: airflows from 500 m3/h up to 2.660 m3/h, pressure up to 300 Pa. Low energy...
