The Rittal air duct system for roof-mounted cooling units and roof-mounted air/water heat exchangers. Cold air may be routed directly to specific areas of the enclosure using this air duct system. The risk of air short circuits due to self-ventilated installed devices is therefore eliminated. The dimensions of the shallow duct are 229 x 1500 x 29 mm ( W x H x D ) and can be shortened to the required length. It includes shallow duct compensating hose. It is use for SK 3209, 3210, 3273, 3359, 3382, 3383, 3384 and 3385.
