Gravita is a leading manufacturer and exporter of all kinds of Lead Alloys i.e. Lead Antimony Alloy, Lead Calcium Alloy, Selenium, Copper, Tin, Arsenic etc.
We have Alloying Kettles of various capacities ranging from 7 – 100 tonnes per batch. They are fitted with high efficiency furnace oil burners equipped with preheating arrangements. Emissions control is achieved by a flexible kettle hood venting into a venturi scrubber attached to an ID fan along with a chimney/stack arrangement. Emissions are regularly monitored to ascertain that they strictly fall within the allowable limits.
