The electrically heated tilting furnaces are characterized by very good melt quality and high melting performance with optimum energy efficiency. They are ideal as a flexible solution for pre-melting but also for direct pouring into large moulds.

K ../12 for aluminum and zinc alloys
K ../13 for copper alloys such as bronze or brass
Free-radiating heating elements on support tubes for long service life and simple replacement
Twelve months warranty on heating elements
Multi-layer insulation for optimum energy efficiency and low external wall temperatures
Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
Incl. crucible
Electro-hydraulic tilting device with safe two-hand operation on the furnace
Uniform and precise pouring due to optimum pivot point
Emergency outlet for safe draining of the melt in case of crucible breakage
No exhaust gas discharge needed
Integrated safety system which continues to operate the furnace at reduced power in case of malfunction in the thermocouple, in order to prevent the freezing of the melt
Over-temperature limiter in furnace chamber for protection against overheating. The limiter switches the heating off when the set limit temperature is reached, and only switches it back on after the temperature has fallen again.
Low-maintenance furnace chamber control with temperature measurement behind the crucible
Defined application within the constraints of the operating instructions

Équipement supplémentaire

Safety fence
Work platform for easy charging
Collecting pan under the emergency outlet
Crucible breakage monitor with visual and audible signal (only for models K ../12)
Bath control with thermocouples in the furnace chamber and in the melt. The furnace temperature is controlled through the melt. Temperature overshoots are reduced, thus the quality of the melt is improved
Heating system operated through thyristors
Multi-step switching of the furnace heat
Models with increased heating power
Process control and documentation via Nabertherm Control Center (NCC) for monitoring, documentation and control
