Character

NAD 100, 250 v1 - Heating water storage tank with polyurethane insulation (PUR 42 mm) and a cower of painted steel sheet

NAD 500, 750, 1000 v1 - Storage tanks NAD with a flange are produced with a possibility to place one flange or up to three flanges. The flange with spacing of screws 210 mm can be used for assembly with the heating flange type TPK. The placement and quantity of the sockets can be changed in dependence of an order. In standard design the flange is closed. Storage tanks are delivered without insulation. The insulation is available on request.
