PHI Atherm Immersion Heater

Prolific Group cooperating with ATHERM to supply immersion heater for aluminium industry. ATHERM is a French company which has continuously improved skills in design of Immersion Heater and industrialization of thermal solution for aluminium die casting holding furnaces over 30 years.

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