Heating and cooling in buildings plays a significant role in creating indoor spaces which are comfortable and healthy for human occupation. However, running these HVAC systems requires energy - a lot of it. Therefore, balancing the need for adequate ventilation with energy efficiency is crucial for both indoor air quality and reducing energy costs.

According to the European Environment Agency, the building sector represents 34% of energy-related emissions, with the largest contributor being the direct use of fossil fuels in buildings for heat. Ironically, burning fossil fuels for heat production also creates local air pollution, requiring ventilation systems to work even harder to clean the air to make it safer to breathe – which in turn increases energy consumption. But it doesn’t need to be this way.

The combined strength of Trane and AL-KO Airtech
Trane and AL-KO Airtech share the common mission of decarbonizing buildings for a more sustainable world. Whether through improved energy efficiency, transition to low-GWP refrigerants or electrification of heat, our innovative thermal management systems are designed to reduce the energy intensity of buildings.
Now, with the acquisition of AL-KO by Trane Technologies in 2022, our combined expertise in thermal systems and ventilation is poised to dramatically increase the energy efficiency of buildings.

With the most comprehensive portfolio of solutions in the HVAC market, we can offer customers the best of both worlds, backed up by the largest service network globally. Let’s look at some examples below.

All-in-one HVAC solution with R290 refrigerant
The well-known AL-KO AT4 complete air handler can now be paired with Trane Leaf air-to-water heat pumps using R290, a natural refrigerant with zero GWP which delivers maximum efficiency in wide operating conditions. The AL-KO AT4 is equipped with the latest generation of variable speed drives. High-performance heat recovery helps to significantly reduce heating costs. Intelligent control options with frequency converters ensure the greatest possible energy efficiency. The robust design ensures a long product life cycle.

The hottest solution on the market
The Trane City™ RTSF HT (High Temperature) heat pump has already changed the game when it comes to electrification of heat, thanks to its ability to deliver hot water up to 110°C. Its super compact size has made it the perfect solution for retrofit projects. And now, it can also be combined with the game-changer in ventilation: the modular AL-KO AT4 ventilation system. Available with horizontal fans and state-of-the-art components that enable vertical air ducting, it is ideal when there is little space available for installation. The intelligent control system and efficient drives ensure highly efficient operation.

Possibilities are endless
