Eurovent launches Desert Certification Scheme for high-ambient HVAC performance

DUBAI, UAE, 5 November 2025: Eurovent said it has launched a dedicated Desert Certification Scheme for air conditioners, chillers, VRF systems, rooftop units and IT cooling equipment, incorporating performance testing at ISO T3 (46°C).

Making the announcement through a Press Release, Eurovent said that air conditioning equipment in the Middle East is exposed to challenging high-temperature conditions during peak summer months. Eurovent explained that while products have been tested previously, those tests did not independently verify performance at peak load conditions.

Eurovent said the new Certification Scheme will provide more realistic performance data at T3 conditions of 46°C, with optional testing at T4 conditions of 48°C, and will incorporate a unique seasonal efficiency calculation (DSEER).

Eurovent Middle East quoted its Technical Director, Ali Nour Eddine, as saying: “In the Gulf Cooperation Council (GCC) region, HVAC systems face extremely high ambient temperatures, yet most equipment is still certified using European or American standards that don’t reflect regional conditions. The result? Certified performances that fail to represent real-world operation. That’s why we created the Desert Certification, a third-party, performance-based scheme tailored specifically to the harsh climate of the GCC.”

Eurovent Middle East also quoted its Managing Director, Markus Lattner, who said: “The problem of failing air-conditioning equipment during peak season is unfortunately still all too common. With this scheme we will provide engineers, specifiers, architects, and consultants with a reliable foundation of proven performance values at high ambient conditions while offering a distinct competitive edge for manufacturers and brands.”

Eurovent said it held an introductory online session on 8 October 2025, and the Desert Certification was presented during its Industry Congress on 28 October in Riyadh, titled HVACR Next Generation – Sustainability in Extreme Conditions, which welcomed all industry stakeholders.
