INDUSAIL SONIC INSTALLATION INFORMATION
Application area
Operation in dry, interior rooms at ambient temperatures of 5 to 40 °C (non-condensing). The unit has been designed for use
in locations where air qualities typical of offices prevail in terms of dust levels and corrosive/oily constituents.
Control and regulation of the secondary air
Application options: ventilation and conditioning of the ambient air using INDUSAIL LUMINOUS plus by secondary air intake
from the room. The ambient air is cooled with a cooler connected to a cooling water circuit.
Control with variable volume flow rates and output control by a cooling valve on the water side: a fan coil controller
(RDG 200 KN) captures the ambient temperature using a sensor integrated in the room thermostat and brings the room
temperature to its set value by activating the water valve and the fan via a continuous control output (0-10 V DC). The cooling
capacity depends mainly on the cooling water flow rate, the supply temperature and the air flow rate. The controller adjusts
the fan speed and the position of the water valve so that the cooling capacity of the INDUSAIL LUMINOUS plus meets the
current requirements. This allows energy costs to be minimised, while maximising comfort.
Kiefer Klimatechnik GmbH accepts no liability for
damage resulting from incorrect use. Deviating operating
conditions require written approval from the manufacturer.
Important: always ensure that the unit is used as
intended in non-condensing operating mode. Failure to
observe this requirement can result in damage to the
unit and cause hygiene hazards to occur!

The coolant can be regulated using a water valve, including a
continuous actuator. The actuator (PWM) is controlled by the
room controller.
If a continuous actuator is not required, we recommend that no
coolant flows through the heat exchanger when the fan is idle.
For this reason, we recommend a shut-off valve.
The controller must ensure that the coolant supply is shut off
when the unit is not running.
