No compromise when replacing traditional AHU installations
Manuel Swärd, Export Director for West Europe at manufacturer IV Produkt, explains why an air handling unit solution specifically designed and optimised for heating is perfect for the UK climate.
Successful and easy way for property owners to improve their energy efficiency class
In spring 2024, the EU Energy Performance of Buildings Directive (EPBD) was adopted. The directive will affect property owners’ opportunities and terms for obtaining financing from banks, which has further strengthened the incentive to optimise energy use.

Easy Access – Simplified site transportation
Major energy savings by replacing older air handling units
The Palladium in Cologne, Germany, hosts concerts, galas, corporate events, trade fairs, and conferences for up to 4,000 guests. To improve comfort, the owner replaced the old ventilation units without heat recovery and added cooling and heat pumps for a better indoor climate.
Improve energy efficiency class by replacing older air handling units
To meet future demands, Skandia Fastigheter is investing in new ventilation at the Nova Lund shopping center – with the goal of moving from energy class D to A.
Smart solution simplified the transport into an older building
In central Oslo, the street Karl Johans gate runs through the city. At Karl Johans gate 2, four Envistar Flex size 300 were installed with the integrated cooling unit EcoCooler. Thanks to the Easy Access concept, the site transport went very smoothly.
