GENERAL DESCRIPTION
PLUG AND PLAY UNIT
Power supply
To make installation easier, AIRCOOLAIR power supply does not
require «neutral» connection. It is powered by 400 V, 3 phases,
50 Hz except size 20S
Circuit breakers
To improve the safety of the AIRCOOLAIR and extend its life,
circuit breakers protect against over-loading, over intensity and
a disconnected supply phase. Maintenance is also improved as
there is no requirement to change fuses. The electrical panel is
manufactured in accordance with EN60204-1 (1998) electrical
directive.
Adjustable ventilation for Split Unit
Airfl ow and external static pressure characteristics are adjusted
in the factory to deliver the right pulley and belt to be the nearest
to the site needs. However, once on site, the real characteristics
of ventilation requirement might be slightly different than theory
measured on drawings: therefore, AIRCOOLAIR Split unit
is delivered as standard with adjustable pulley opened. This
remains the possibility to adjust the airfl ow accurately at the
commissioning and fi nd the perfect airfl ow for the site comfort
and system effi ciency.
EXTENDED LIFECYCLE
Assembly quality, compliance to PED 97-23, EN 60204-1, CE,
made in an ISO 9001v2000 factory.

Refrigerant pressure reading :
No need to access to refrigerant pressure gauges.
Refrigerant pressures and superheat on each circuit can be read
directly on the service display DS60 or a BMS as all units are
equipped with high and low pressure transducers and refrigerant
suction temperature probes
Easy access
All access to internal components of the AIRCOOLAIR units are
closed by panels equipped by locks and handle for quick and
easy dismounting. No more screws are used as panel fi xtures.
What makes the difference are the small details which have given
