Porthole cover seal

for the aluminum industry

Porthole cover Seal Immediate reduction of 71% of thermal losses (*) Replacement in less than 1 minute (*production site of +/- 470,000 T/year, on a 2,500 Exhaust Port cover’s furnace, ID210 mm) Find out more To keep the area under pressure, the tightness of the openings is also pivotal to reduce to a minimum the air ingress which definitely interfere in the process and lead to the dilution and cooling of the combustion air, thus preventing the self-ignition of gases in the furnace. Designed and delivered in made-to-measure rings, they fit together quickly as easily on opener lids as on travelling thermocouple lids (for which a reinforced version has been specially designed). Ceramic-free High thermal resistance Quick maintenance Abrasion resistance Immediate sealing Delivered in a ring = increased use value = easier storage = optimised inventory management
