The training stand with a frame made of grooved extruded aluminium profile can be used flexibly thanks to the castors and is equipped with a fully functional Helios air-conditioning unit. The unit has a weather protection grille on the inlet and outlet side, which is directly connected to the ventilation unit via insulated pipe sections. There is a silencer in each of the supply air and extract air streams. A distributor on the front side supplies air to the discharge valves on the front and rear sides respectively. All valves are adjustable to suit the air requirements of the room. All parameters are sent from the unit via LAN or WLAN to a tablet (included in the scope of delivery) and can be displayed at any time.
