Shells of our circular heavy duty magnets are made of highly permeable steel casting that is as per IS:449 (BSS-1617). These are properly machined and provide the most efficient and accurate Magnetic Circuit. The periphery of the magnets is heavily ribbed giving an added mechanical strength & an increase in the radiation surface to help cooling. The center and outer poles are machined using highly permeable magnet steel that has cored recesses arrangements. This protects the heads through tensile bolts. Its terminal box is specially designed to ensure protection while it is in operation.
