Over Filling Guard

If you need to be more than 100% safe and want to avoid overfilling your launders at any cost, the OFG (Over FIll Guard) can be installed as an additional protection and failsafe redundancy


The OFG-285 consists of a main unit with a safety circuit and a swing arm conduit to an electrode head. The main box can be mounted to brackets 50 mm (2″) outside a launder. The electrode head is swung over the molten metal and leveled so that the ends of the electrodes hit just above the maximum allowed level in the launder.
