The high energy efficiency of 1.12 W/cm3 and the innovative control of the heating are responsible for low consequential costs in the daily use of the furnace. In addition, they guarantee a long service life of the individual molybdenum disilicide elements (MoSi2), which can be replaced individually in case of failure
Time and energy efficiency play an important role in the modern dental laboratory. Therefore not only conventional sintering cycles, but also speed processes can be programmed in the S400 in order to be able to work with the greatest cost-effectiveness. All heating phases (maximally five) allow the free input of a heating rate from 1 °C to 100 °C/min. The sum of all holding times is 420 minutes at the most.
The proven TTC mode (time-temperature-cooling) is available to you in the VARIO S400. The special feature of this process is that the sintered objects are returned to room temperature in an actively controlled, linear cooling process in order to avoid damage.
In case of an unforeseen brief interruption in the power supply, the PFC is activated: the electronics then decides whether the sintering process is aborted or ended normally, depending on the temperature loss that occurs. In any case, at the end of the program the user is informed on the display of the duration of the interruption during a ramp-up or holding phase so that the quality of the sintered object can be assessed.
The four molybdenum disilicide heating elements ensure the homogeneous distribution of heat in the firing chamber. Zirconium frameworks are manufactured to the highest quality standards, whether a conventional sintering process or the time and energy-saving speed process is used.
The newly developed Zubler sintering dish system is characterized by special material characteristics in daily use. In a similar way to a thermal protective shield, the high-purity material ensures a homogeneous distribution of the temperature inside the carrier and protects the sintering objects against discolorations.
This program protects against the „burning“ of the heating elements. A sort of protective layer is thereby formed on the surface of the heating rods and prevents deterioration in the effectiveness of the heating. The service life of the heating elements is noticeably extended.

High-quality molybdenum disilicide heating elements reach a maximum end temperature of 1.650°C. Unlike silicon carbide heating systems, heaters of this type are far enough away from their maximum performance limit of approx. 1.800°C. Thanks to this property they attain a significantly longer service life. Each of the four heating elements can be individually replaced in case of damage – an „en bloc“ replacement is unnecessary. When calculating the energy consumption of a furnace taking into account the volume of the firing chamber, an energy density of 1.12 W/cm3 results for the S400. This very high energy efficiency means low operating costs in daily use. A type-B thermocouple is designed for a maximum temperature of 1.800°C. The processing temperature of maximally 1.650°C for zirconium oxide lies well below that – a fact which, at the end of the day, is reflected in a longer service life of the thermal sensor.
