It is a vacuum furnace series of small dimension for laboratory
and industrial applications.
The hot zone has a cylindrical shape and
top loading . VLT U.H.V. furnaces are completely
metallic and at the state of the art in the U.H.V. technology.
The use of metals as Tungsten, Molybdenum, OFHC Cupper, AISI
304L and the use of Turbo molecular and dry pumps, allows
to perform high vacuum processes in an atmosphere oil
The high efficient metallic hot zone allows
very fast heating and cooling cycles. With a very low power
The furnaces can operate in automatic or manual, and the
operator interface is very simple.
Process data can be transmitted to a remote PC.
VLT can supply different furnace configurations , responding
to specific client needs.
The furnace is a self contained machine in a structure of
extruded Aluminium alloy, with the instrumentations in the
front panels and doors in the 5 other sides.
In the rear side there are inputs for Inert gas, cooling
water and compressed air.
This H.V. Furnace series is supplied for working temperature
of 1200°C, 1500°C and 1800°C, the useful volume
can be from 2lt to 20lt, with a maximum diameter of 220mm.
The overall dimensions of the furnace is related to the Hot
Due to the high efficient thermal shields the power consumption
is very low i.e. for a useful volume of 8lt at 1500°C
the power required is less than 5 Kw.
