Most industrial radiators have bolt-on tanks so gaining access to the core is relatively simple. Once open, the core can be flushed with water and blocked tubes cleared. ‘Rodding out’ is the process of carefully inserting a thin metal rod down each tube to force the debris out and restore normal coolant flow.
It may be time-consuming work but it is much less costly than a replacement core. While open, the core can also be inspected for signs of damage and any repairs completed before the radiator is reassembled and tested. Fasteners and gaskets may also need replacement if they are damaged or worn.
Adding a descaling treatment to the cooling system at regular intervals can be helpful to maintain a healthy cooling system and prevent blockages. Ask Natrad for help in choosing the best treatment products for your application.
