THE FLEXIBLE ACOUSTIC SAIL SYSTEM
INDUSAIL SONIC
ACOUSTICS – COOLING – AIR – LIGHT REFLECTANCE
INDUSAIL SONIC plus function description
The fan draws ambient air into the unit via a lter cell and channels it through the heat exchanger. The air is cooled by the
cold water owing within the heat exchanger. The cooled secondary air is then introduced into the room from four sides,
in a highly inductive, draught-free manner, through Kiefer air di󰀨users, type INDUL P18. The lter cell protects the internal
components from soiling.
P The supply water temperature
must be calculated to ensure
that no condensation forms
during correct operation.
As an option, it is possible to feed preconditioned outdoor air into the sail via an air
connection (DN 125). This outdoor air is used to maintain the intended minimum outdoor
air ow rate for the room (DIN EN ISO 15251).
The air ow rate, sound power and caloric output are important considerations for the unit
design. The caloric output of the units is determined by the amount of water – controlled,
for example, by a water valve – and the speed of fan rotation. The fan speed is controlled
by regulating an EC motor with a 0 to 10 V (DC) signal from a controller or the building
management system. The sound power of the unit is determined by the speed of fan
rotation and the air ow rate.
INDUSAIL SONIC is a exible acoustic sail with
integral fan coil for ambient air conditioning. It
supports the most common types of lighting thanks
to its high light reectance value > 90 %. The recircu-
lation air or mixed air is induced via highly inductive
linear di󰀨users, with an optional fresh air intake to
improve the ambient air quality. By combining active
and inactive components, the requirements of di󰀨e-
rent o󰀩ce concepts can be fullled, even in the event
of future changes.

PART I-5
INDUSAIL SONIC air function description
INDUSAIL SONIC air works without an air cooler and has been designed to introduce preconditioned outdoor air only.
Thanks to the low supply air temperatures that can be achieved with this design, high cooling capacities are also possible
while maximising interior comfort.
INDUSAIL SONIC silent function description
Although this version does not have a ventilation function, its outer coating of highly absorbent insulating material achieves
very good sound absorption and therefore improved interior acoustics. It also serves as an additional design element.

ACOUSTIC SAIL SYSTEM COMPLEMENTED
BY COOLING AND VENTILATION
INDUSAIL SONIC acoustic absorption
The high sound absorption values of the sails are achieved thanks to especially e󰀨ective materials and their optimal
arrangement in the sail. All three sail types are equipped with sound-absorbing acoustic eece on the room side. The
specied sound absorption values were determined in accordance with DIN EN ISO 354 and DIN EN ISO 11654 by an
external institute for sound-related product optimisation. The INDUSAIL SONIC silent sail is additionally equipped with a
highly absorbent insulating material made of polyester, which achieves a particularly high sound absorption at di󰀨erent
ceiling distances.
P Flexible design of o󰀩ce spaces coupled with complex acoustic requirements can be
implemented using the SONIC range. Kiefer Klimatechnik supports you in producing an
optimal system design.
Optimising the interior acoustics
Acoustic sails can reduce nuisances such as noise in interiors. This improves working conditions and performance. In open-
plan o󰀩ces in particular, it can often be hard to concentrate when others are talking loudly. Audibility in the room, increased
speech intelligibility and low reverberation times are important room acoustic criteria that increase the acoustic quality of the
room and thus the productivity of the users. The ceiling is the largest continuous surface in a room and can reduce sound
propagation with sound-absorbing ceiling sails. This increases the wellbeing, satisfaction and performance of the people in
the room.

INDUSAIL SONIC silent sails are additionally equipped with
a highly absorbent polyester insulating material on the back.
This results in particularly high sound absorption values. The
sound absorption of the “plus” and “air” sails is independent of
the distance to the ceiling, as there is no acoustically e󰀨ective
material on the back of these sails.
S
The INDUSAIL LUMINOUS “plus” and “air” achieve the same
sound absorption, as the surface area of the acoustically
e󰀨ective material is identical.
