Product Description
STULZ CyberAir systems are designed to be the
most versatile and flexible floor mounted air
conditioning systems in the industry. The unit is
available in air-cooled, water-cooled or glycol-cooled
configurations and
have upflow or down flow air patterns utilizing highly
efficient, electronically commutated (EC) fans.
STULZ CyberAir systems are designed to supply air
to only one room.
STULZ CyberAir systems incorporate two cooling
circuits with highly reliable scroll compressors.
They are designed to operate with R-410A
refrigerant. The cooling capacity, in kW, will
depend on the unit size
which can range from 21 to 105 kW (1 kW = 3415
BTU/ Hr). Refer to the unit nameplate to identify the
model number and cooling capacity of your unit.
NOTE
STULZ CyberAir systems are strictly for
non- residential applications.
The functional modes of operation, in addition to
cooling, are heating, humidification, dehumidification
and filtration which provide complete environmental
control of a conditioned space.
There are two air flow pattern configurations, upflow
and downflow, and several cabinet sizes based
on the type of system and capacity. Regardless
of configuration, STULZ CyberAir systems are
compact and versatile. See the Installation
drawing provided with your unit for the layout
and dimensions of the cabinet.
The STULZ CyberAir unit is provided with a
factory mounted, main power disconnect switch
with a lockable handle. The disconnect switch
electrically isolates the unit during routine
maintenance. The system incorporates state of
the art component protection with the use of
motor start protectors or circuit breakers.
The advanced
E²
microprocessor controller is
provided as a standard for STULZ CyberAir
systems. This controller provides superior features
for more comprehensive control of the unit. These
features include full alarm system; input/output
monitoring status; full integrated control of heating,
cooling, humidification, and dehumidification;
multi-A/C unit control and remote communication
with building management systems.
The controller user interface display panel is
typically mounted on the front door of the A/C unit. It
features a high resolution touch screen display
offering enhanced graphical display capabilities and
a round membrane type keypad to navigate through
the controller menus and adjust operating
parameters.
An easy to read, backlit liquid-crystal
alphanumeric display panel is also available as
an option.
