An air handling unit (AHU) helps maintain a high-quality indoor environment by controlling the supply of fresh and well/tempered air. Swegon’s GOLD and SILVER RX units are designed for comfort ventilation. To ensure superior performance, Swegon designs its own components, such as the rotary heat exchanger, fan impeller, and control equipment. Units with rotary heat exchangers allow to achieve the ultimate indoor temperature and annual energy efficiency; heat exchangers with turbulent air flow are uniquely effective. This combined with the short installation length typically makes them the first choice for most applications. The turbulent flow in the rotor and the Carry-Over Control feature make them ideally compatible with VAV and DCV system applications. Swegon’s GOLD and SILVER RX units are designed to minimize the risk of air and odor transmission between the air flows. The reference unit weight of a GOLD RX in size 012 is 509 kg, however, the weight can differ between different configurations. In terms of material content, our AHUs consist primarily of steel, to a large extent recycled and renewably produced, aluminium, different types of polymer materials, insulation material, and electronic components. For this individual product 73% of the steel comes from recycled materials. Our AHUs are expected to be used for 20 years before they reach the end of life.
