The overcurrent fault protection (OFP) in heat treatment

Temperature adjustment and control are critical in heat treatment applications. The overcurrent fault protection (OFP) fuses are usually used to protect systems from breakdowns. But these fuses are very expensive because they involve very precise and repeatable melting energy.

Gefran has patented a new solution that guarantees savings in terms of cost of replacement parts, labor, and down-time.

Case Histories for Heat Treatment

Heat Treatment - OEM, System Integrator, End User
Isoclima (B.H.T.) -  High performance glass

Isoclima (B.H.T.) - High performance glass

ISOCLIMA is the world’s leading producer of high-performance glass.
B.H.T. srl builds furnaces to temper curved and flat glass, and required an efficient application to manage a furnace with 520 temperature zones for a flat glass production plant.

Linn - Inductive heated lab furnace

Linn - Inductive heated lab furnace

Linn, a specialist in industrial furnaces, needed to setup an induction for melting tests on several metals (from platinum to iron). Induction furnaces are electrical furnaces in which the heat is applied by induction heating of metal.
The advantage of an induction furnace is a clean, energy-efficient and well-controllable melting process compared to most other means of metal melting.
