RSVC VAV Circular Terminal Units

VAV Circular Terminal Units Comfort Variable Air Volume (VAV) HVAC systems are the best solution to guarantee high levels of comfort and energy efficiency in civil and industrial applications. VAV systems are well suited for the climate control of modern office buildings, with extensive glass facades and variable occupancy levels which cause uneven cooling loads profiles, with relevant values even in the winter season. For industrial process applications, such as research laboratories, the use of VAV systems allows to maintain the required differential pressure levels between adjacent rooms together...
