Aldes fans beat the heat on power use

01 July 2011

THE Aldes Group, a major player in the European ventilation market, has developed a large range of energy-saving fans to meet the global requirements of reducing power consumption and protecting the environment.

The products use innovative micro-watt technology developed by the French company to control the duct static pressure and ensure the economical operation of the fan.

“Countries worldwide are drawing up new regulations to decrease the energy consumption of buildings, and thus save the planet’s resources. Among such countries is the UAE, which tops the WWF (Worldwide Fund for Nature) International’s list of countries with the largest ecological footprint. The UAE government has indicated its firm commitment to address these environmental concerns,” says a spokesman for Aldes Middle East, which is based in Sharjah, UAE.

In order to meet the new regulations and the needs of people in every country, the company has created a large range of fans using micro-watt technology, says the spokesman.

Amongst these products are exhaust fans with C4 classification such as C VEC micro-watt+ and inoVEC micro-watt; and supply/exhaust fans including VIK micro-watt and TVEC GII micro-watt.

“The most innovative product of this range is the C VEC micro-watt+, which is part of a new generation of cabinet fans with C4 fire classification. It brings further energy saving through a large range of functionalities including programmable curve, fan history and parameter changes,” says the spokesman.

“Micro-watt’s specific electronics drives the motor speed through frequency variations and controls a continuous pressure on the fan’s airflow range,” he says. “This exclusive concept has numerous advantages, including saving of up to 75 per cent on electrical consumption; savings on the three-phase line voltage, thanks to a 50/60 Hz single-phase power supply up to 2.2 kW motors; return on investment (RoI) within four years, due to the energy savings made during the operation; easier settings, thanks to the adjustable potentiometer and the pressure display; and sound reduction into the grilles through adapted airflow, contrary to a classical installation.”

Aldes has developed a wide choice of micro-watt fans to ensure that there is a product that suit any need and building. Included in this range are air exhaust fans with C4 fire classification (400 deg C with half-hour fire rating). The inoVEC micro-watt, a new generation of low-consumption C4 fan-units, falls in this category. It has airflows of up to 12,000 cu m per hour, and offers up to 75 per cent of reduction in energy consumption, the spokesman claims.

Another product in this category is the C VEC micro-watt+ with airflows of up to 2,500 cu m per hour. With an Aldes patented system, C VEC micro-watt+ fans provide considerable reduction in consumption through the control of a constant or rising pressure on the fan’s airflow range.

The C VEC micro-watt+ is also unique in that it is the first C4 fire-classified fan to integrate an electronically-commutated (EC) motor, ensuring really low energy consumption with high control possibilities, says the spokesman.
Beyond an airflow display and an integrated overvoltage of 400 V and lightning protection, C VEC micro-watt+ fans offer several new functionalities including programmable curve, fan history and parameter changes. They also provide up to 60 per cent of savings on electricity bills.

The Aldes range also includes the VIK micro-watt and TVEC GII micro-watt, air supply or air exhaust fans with pre-treatment modules featuring filters and heaters and sound attenuators. “These two fans can cut electrical consumption by up to 40 per cent,” the spokesman says.

Aldes Middle East covers all the applications inside a building in terms of ventilation. “From individual villas and residential buildings, to commercial and industrial premises, Aldes creates and manufactures products that provide clean air, comfort and safety inside buildings,” he says.
