Thermaltek manufactures electric furnace systems for melting, holding and transferring non ferrous alloys including aluminum, magnesium, brass and tin.

Hot and Cold chamber furnaces for magnesium melting with thermally efficient, high temperature fiber lining to minimize thermal losses through the furnace walls, with a high alumina cast refractory floor. This allows the furnace to melt at higher capacities, translating into more production for the customer.

Thermaltek recycling/re-melting furnaces are used for all classes of magnesium scrap, including scrap parts, biscuits & runners. Our heating equipment is used in both dedicated recycling plants and in-house re-melting operations.

Thermaltek manufactures ovens for heat treating & stress relieving magnesium castings: A high temperature recirculating forced air heating system for efficient and safe processing of the castings.

Heating elements are designed for long life and reliability. Typical life expectancy is between 5 and 10 years. Multiple heating elements are connected in parallel to insure the minimum percentage of power goes down if an element fails. Elements can be controlled separately in the height of the furnace for better temperature control. The open coils are freely radiating which allow the wire to operate at minimum possible temperature for maximum life. In the event of a failure the wire can be easily repaired by welding. Heating elements are placed in all four sidewalls and the floor to give even heat around the crucible and maximizes the surface area available to transfer heat.
