Buildings destined for office use are increasingly characterised by lighter building structures, with an emphasis on glass walls and rooms where the eventual professional use is unknown at the design stage. The presence of opposite overlapping heat loads which can vary suddenly calls for machines and systems which offer elevated flexibility of use; ensuring adequate air exchange is essential in improving employee productivity whilst minimising the costs associated with ventilation. The Aermec product range takes all of these needs into consideration, offering dedicated fan coils, heat pumps and multifunction units; or alternatively VRF direct expansion systems which can exploit heat and cooling energy recovery. These are combined with reliable and efficient air treatment solutions which can be tailored to suit all users, from the biggest to the very smallest.
