PHI Atherm Immersion Heater

Prolific Group is cooperating with ATHERM to supply immersion heaters for the aluminum industry. ATHERM is a French company that has continuously improved its skills in the design of immersion heaters and industrialization of thermal solutions for aluminum die casting holding furnaces over the past 30 years.

One of the ways of melting aluminum is by using an immersion heater. Aluminium Industry has been one of the versatile industries, as aluminum materials are used in many other industries such as automotive, aviation, food packaging, and many more. One of the basic parts of aluminum production is the melting of aluminum scrap or chip or ore.
