UNITED IN INNOVATION.
COMMITTED TO SUSTAINABILITY.
The new integrated system combining the AL‑KO AT4 Complete air handling unit and the Trane Leaf heat pump brings together advanced ventilation and climate technology in one highly efficient, sustainable solution. It is designed to support future‑ready buildings, lower emissions, and maximize energy savings – across both new construction and existing buildings.
Where Innovation Meets Sustainability
According to the European Commission, buildings across the EU account for 40% of total energy consumption and 36% of greenhouse gas emissions. Reducing these figures requires the right technical system solution – one that delivers efficiency, sustainability, and long‑term economic value.
AL‑KO Airtech addresses this challenge with advanced air handling systems (AHUs) that intelligently combine indoor air quality, energy efficiency, and operational reliability. By integrating the customizable AL‑KO AT4 Complete air handling unit with the high‑efficiency Trane Leaf air‑to‑water heat pump, we introduce a forward‑looking solution designed to support modern, low‑carbon building strategies.
