Energy concept Daikin leads the way in energy efficiency and the Energy series represents the ultimate in air handling units. The D-AHU Energy has been designed to optimize the energy consumption and thus minimize the running cost, When compared with standard AHUs, this means lower seasonal (year-round) power consumption and a reduction in the overall energy bill. Eurovent Certification Daikin is participating in the EUROVENT CERTIFICATION Programme for Air Handling Units. Daikin Air handling units are certified under the number 11.05.003 and presented on www.eurovent-certification.com. ASTRA Air Handling Unit selection software and performances are certified according to EN 13053-1999.

In terms of value, the energy costs represent, on average, 70-80% of the total life cycle cost and to keep this to a minimum, we have built our AHUs to deliver exceptional mechanical performance (in accordance with EN 1886) and to avoid energy loss through the casing and structure and this is certified through the EUROVENT programme.
