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.

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.

High heat recovery in the new terminal at Oslo Airport

A new terminal has been inaugurated at Gardermoen for travelers to and from Schengen. We at IV Produkt, together with AF Energi AS, have delivered 12 large Flexomix air handling units.

Focus on high heat recovery

The project focuses on a high degree of heat recovery. The total air flow is 94 m³/second (340,000 m³/h).

Oslo's international airport is getting a long-awaited expansion of 30,000 m². The end customer Avinor AS expects to be able to handle 35 million passengers annually due to the expansion.
