Industrial Precision
Precise Temperature Profile
Controlled gradual cooling with an automatically generated temperature profile eliminates internal stress and guarantees the strength of the final products.
Energy Efficiency
300 mm insulation and advanced TIA Portal control system optimise energy consumption while maintaining the precise temperature profile.
Modular Construction
Adjustable lehr length and capacity thanks to a modular approach — easy expansion without complete reinstallation.
