CASA duct coils for
®
cooling the supply air
Waterborne cooling duct coils
Duct coils for installation in the supply air duct, for cooling the supply air. The lowest coil height is only 255 mm,
which permits installation in a suspended ceiling.
Swegon CASA Smart control technology for ventilation
units aims to regulate indoor air according to the settings.
The control mode and the settings can be changed from a
CASA Smart control panel.

Three different sized chillers for the supply air duct:
• CASA CWK 160-3-2.5 (Cu 10 mm), whose height
(255 mm) means it can be housed in a suspended
ceiling, among others, in multi-storey buildings.
• CASA CWK 200-3-2.5 ( Cu 22 mm)
• CASA 1024VL (Cu 22 mm)
• Brackets included
• Thermal insulation 10 mm
•
•
•
Maximum operating temperature of 150 degrees
Maximum operating pressure of 1.0 MPa (10 bar)
Valves are selected for the size of the chiller

The function of the duct coil is controlled from a
control panel via an adjustable room temperature
setting. Valve TV1 is controlled by the room
temperature, according to the options:
Operating release for cooling is given based on the CASA
ventilation unit's internal outdoor temperature sensor T1.
The temperature after cooling T4, can, for example, be read
on a Smart panel.
1.
The following applies to the ventilation unit and system:
• Unit equipped with a Smart control system
• Smart control panel with 20 m long modular cable
• At least one, in the outside air duct positioned shut-off
damper SD1, control signal is obtained from the circuit
board 24 VDC, max. 2 W
• Heating and/or condensation insulation of the supply
air duct coil and condensate pipe
• Venting of the pipe system
• Balancing of the pipe system/coil
By a temperature sensor comprised by a CASA
Smart control panel.
2. By a separate room temperature sensor T8
(accessory).
3. By unit's internal extract air temperature
sensor T3.
