CyberAir 3PRO DX ASR

Maximum efficiency and optimum air distribution thanks to underfloor fan section

The CyberAir 3PRO DX ASR is the result of consistent further development of our thoroughly successful CyberAir 3 series. To reach maximum cooling performance with minimum floor space and maximum potential savings, we have developed the CyberAir 3PRO DX ASR series with underfloor fan section. Due to our long-term experience with worldwide projects we can present a product that offers even more flexibility and efficiency.

CyberAir 3 DX ASR air conditioning units in the standard door size are available as optimized energy and optimized output versions. The six sizes range from 950 to 3,110 mm in width.

New series promises major potential savings

The new ASR series comprises a heat exchanger and fan module. Installing the fan module in the raised floor reduces pressure drops and improves energy efficiency.

The series offers:

Reduced fan power consumption thanks to its location in the raised floor
More sizes of EC compressor
Increased cooling capacity per footprint
Enlarged filter areas
GE and GES units with early switchover to Free Cooling mode, thanks to the enlarged heat exchanger surface

This series is available for A, AS, GE and GES systems.

Benjamin Petschke, Product Manager

"The new units of the CyberAir 3PRO DX series combine maximum reliability and unbeatable efficiency in an unique way. Who relies on it can only gain."
