STANDARDS: EN 12697-1 clause C, EN 13108
Designed for high temperature heatings.
Structure composed of in sheet-steel, frontal furnace in diecasted
steel to avoid the aggretion of the acid smokes. The thermic insulation
in ceramic fibre avoids the smallest heating leakage saving
energy accordingly. Electronic regulation of the temperature is
obtained through a digital thermostat. This furnace is also used for
the determination of residual mineral matter deriving the incineration
of bituminous mixtures to (EN 12697-1 clause C Standard).
