The intelligent, modular system: three sizes and two types of heating

Series 6000 vacutherm

®

ovens uncompromisingly meet all demands relating to heat
treatment in vacuum, whether simple routines or complicated processes up to 400 °C
are involved. Starting with high quality standard models, application specific configu­rations can be realised through selection from a wide range of equipment options.

User comfort

With the inert gas connection
incorporating a precision valve,
process gas is dispensed
accurately. Drying times are there­fore reduced and condensation
is prevented. Furthermore, the
precision valve can safely prevent
blowing of powders when the
vacuum chamber is ventilated.

Cleaning

The vacuum chamber has electro­polished surfaces and rounded
corners, and is therefore easy-to­clean.

Corrosion resistance

The vacuum chamber is made of
high quality stainless steel (1.4571)
with outstanding corrosion
resistance.

Economic viability

With their high quality standard
features, extreme reliability and
state of the art safety concepts,
vacutherm®ovens offer the best
price/performance ratio.

Safety tested

Kendro has set new safety stan­dards with Heraeus®vacutherm

®

6000 Vacuum Drying Ovens.
With the double-pane door made
of safety glass, for instance, im­plosion protection is guaranteed
throughout the equipment's
working life. The glass cannot be­come brittle or dull as with plastic.
Special versions are available for
drying applications that involve
flammable solvents.

Process safety

With heating systems that have
been tried and tested for decades,
uniform and reproducible drying
and heat treatment is ensured.

Time saving

Jacket- or shelf-heating results in
reduced heating-up times.
Process times are up to six times
faster than in conventional
Vacuum Drying Ovens.

High tech equipment

Water: Lower pressure means lower boiling point

DIN EN ISO 9000

Vacuum applications offer
many benefits:

■ Gentle drying of heat sensitive

materials

■ Significantly reduced drying

times

■ Residue free drying of intricately

designed parts

■ Elimination of oxidation

associated with heat treatment

■ Safe drying of flammable

solvents

■ Targeted recovery of degassed

products

prevents overpressure inside the
vacuum chamber

■ DN 25 access port in the rear

wall

Two types of heating

The vacutherm®6000 series is
available with two different types
of heating:

■ model M, jacket heating:

Heat transfer from the vacuum
chamber via the shelves to the
load

■ model P, shelf heating:

The shelves incorporate heating
coils. Heat is transferred directly
to the load.

The benefits of shelf
heating

The direct energy transportation
ensures rapid heating-up and
process times. Drying process
times can be reduced as much
as 6 fold compared to standard
drying methods.
