USED 2010 ITALIMPAINTI FIM/20TPU
Overview
Description
The furnace is ideal to melt precious metals. All ITALIMPIANTI ORAFI induction-melting furnaces are fitted with static frequency converters. A high efficiency of the electrical output that drastically reduces electricity consumption, maintaining the production rate, is obtained by the frequency conversion system used. The modular construction of the electric circuit board greatly simplifies maintenance operations and guarantees high reliability even in the most demanding working conditions. The highest technical standards used to design the inductors along with the modular construction and the use of only high-quality materials guarantee maximum production even in the worst conditions.
The converter is fitted with a centrifugal pump to recycle the cooling water, fitted with a
pressostat, thermals, fuses and a timer to automatically stop the pump. You require only a storage tank for demineralised water or a water-cooling plant.
Interchangeability of the crucible to melt different precious metal alloys
Display monitoring of the working parameters of converter as voltage and absorbed power.
Computerised alarm diagnostics for as many as 12 alarms or warnings that the worker must take note of for the system to work properly. Instructions and advices are shown on the display.
Closed ring power regulation, which allows the system to absorb the set power regardless of the quantity and type of metal to melt.
The internal environment of the converter is conditioned by an air-water exchanger
