Decentralised ventilation – energy efficient, individual, technically perfect TROX shows progressive solutions at the BAU 2015

The FSL-U-ZAS under floor unit has a maximum height (including grille) of only 195 mm (maximum height when installed in a false floor: 140 mm) and a maximum length of 1150 mm; it is hence ideal for refitting ventilation and and air conditioning systems in refurbishment projects.

The TROX TROX SCHOOLAIR units have also been enhanced. The decentralised ventilation units provide individual and energy-efficient ventilation of classrooms, playrooms in daycare facilities, and rooms in similar establishments. They are an equally good solution for office and administration buildings where high air quality is a must. 

A new introduction at the BAU 2015 is SCHOOLAIR-V-1800, which is only 1800 mm high and provides a volume flow rate of up to 300 m³/h. This means that there is now also a decentralised solution for refurbishments with a concrete façade that is typical of the 1970s and does not allow for larger units. 

Special features of TROX SCHOOLAIR-V-1800 include:

• Demand-based operation (VOC)
• High-efficiency EC fans
• Low specific fan powers (SFP)
• Indivitual room temperature control
• Change to energy efficient secondary air operation 

Low investment costs, simple design, and uncomplicated and rapid installation, e.g. during school holidays, make decentralised units an attractive option for municipalities.

With dimensions of only 600 x 1800 x 349 mm (WxHxD), SCHOOLAIR-V-1800 is ideal for refitting ventilation and air conditioning systems in school buildings that date back to the 1970s 

VentoTec is a joint project of TROX and SCHÜCO for the development of the world's smallest decentralised ventilation unit for non-residential buildings; the unit provides a volume flow rate of up to 100 m³/h and is perfect for office buildings. The possibility of a concealed installation into a façade with sandwich panel and choice of any outer casing both on the inside and on the outside gives architects almost unlimited freedom of design. The unit is controlled with a selector switch, a control panel with LCD in combination with PIR sensors, or via LON from the central BMS, depending on the variant. As options, air quality and humidity sensors can also be used for demand-based control. The decentralised ventilation unit can be installed while the façade is being erected.
