INDUSAIL acoustic sail system

Acoustic sail system developed for modern office concepts, which can be tailored as required to the specific design and requirements, combining the following aspects:

Acoustics – Light – Cooling – Ventilation

« back to overview



Low energy demand due to decentralised recirculating air cooling adapted to changing cooling loads and the option of using free cooling. Energy saving EC fans increase energy efficiency.


Multifunctional system combining the areas of acoustics, lighting, cooling and ventilation, to offer maximum flexibility when designing the office landscape.


Acoustic elements with a high light reflectance value and integral, decentralised recirculating air cooling system for cooling the interior, with the option of inducing supply air.



Acoustics – Light reflectance – Cooling – Ventilation

Active acoustic sail consisting of an acoustic panel and a recirculating air cooling unit for cooling the ambient air and improving the acoustics of the room. Supports the most common types of lighting thanks to its high light reflectance value. The air connection socket can optionally be used to introduce supply air. It is also possible to integrate active lighting with the INDUSAIL LUMINOUS.

Acoustics – Light reflectance – Ventilation

Acoustic ceiling sail with fresh air supply only; no recirculating air cooling. With a similar visual appearance to the INDUSAIL PLUS, it increases the supply air volume and improves the acoustics of the room.

Acoustics – Light reflectance

Acoustic-only panel, similar in appearance to the INDUSAIL PLUS (QUADRO). The acoustic ceiling sail is designed for sound absorption and light reflectance only, to improve the acoustics of the room and serve as an extended design element.

The lighting unit can provide additional active lighting to all INDUSAIL components.

  • Beleuchtung teilweise

  • Beleuchtung komplett


Flexible acoustic sail system with integrated fan coil system for ambient conditioning taking account of illumination technology. With the INDUSAIL PLUS (QUADRO) recirculation air or mixed air is introduced using highly inductive linear diffusers, optionally with supply air connection to improve the ambient air quality. The combination of active and inactive components makes it possible to meet the requirements of various office concepts, and even future changes.  Modifications to the partition wall locations has no effect on the arrangement of the ceiling elements if planned appropriately.

Cooling Capacity up to 1600 W
Dimension Sail 1100 mm x 2500 mm
Cold water temperature from 16°C
Operational mode non-condensing
Installation height 255 mm
Recirculation air flow rate 200 - 800 m³/h
INDUSAIL ambient air flow

INDUSAIL SYSTEM ambient air flow

The integrated linear diffusers with their special developed discharges geometry produce fine individual jets. Ambient air can be induced effectively on the surfaces of the individual jets.
