VENTILATION Air Handling Units Overview


AHU is the range of Air Handling Units for civil and industrial buildings for thermo-ventilation and air conditioning purposes, designed to be connected with AIRSTAGE™ Series Outdoor units. Units are available in different models and several additional modular sections to meet all installation needs, with air flow ranges varying from 4,300 to 18,100m³/h and covering a cooling capacity from 25 to 96kW.


AHU is made of extruded aluminium profiles and nylon angle bars. The “sandwich-type” double-skin panels (50 mm thick) with galvanised sheets, externally pre-painted, and thermal insulation in high density polyurethane foam are fastened on the units by means of an aluminium snap-in locking system.


AHU fan section is equipped with EC Inverter Plug-Fans and is provided with Automatic Regulation Control Systems for Constant Air Flow and Constant Available Static Pressure. An electronic device with pressure sensors on the system and control sensors on EC Plug-Fans adjust the flow rate and the available static pressure to keep the air flow constant.
