VACUTHERM®6000 – USER FRIENDLY AS NEVER BEFORE
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

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.

Vacuum pumps for Vacuum Drying Ovens: high quality, power and a long life
HMD 8 three-step diaphragm pump
Standard pump for drying processes involving water and non-caustic vapours. Features: condensate trap and drain cock. 100 % oil free, requires little maintenance. Short pump­down times. Suitable for all vacutherm®6000 ovens.
HMD 4C three-step diaphragm pump
Chemical pump for drying proces­ses involving caustic/corrosive
vapours. Fully lined with PTFE and other fluorinated hydrocarbons. Functional design: integrated glass condensate trap and an emission condenser with cooling, supplied as standard. We recommend this pump for all vacutherm®6000 models in particular the BL versions for flammable solvents (see page 8).
HMZ 2C two-step diaphragm pump
Features like HMD 4C but exclu­ding emission condenser. Due to its low pump volume, we recommend it for model VT 6025.
HRE 8 one-step rotary vane pump
Precision vacuum pump designed for low pressure applications (<1 mbar). Features: condensate trap and drain cock on the suction end, trap with integrated oil filter on the pressure end and permanent gas ballast. Suitable for all vacutherm
®
6000 ovens in particular for heat treatment without liquids.
vacucenter®is not designed for use in BL-versions (for flammable solvents).

Vacuum Drying Ovens for flammable solvents
VT 6060 BL with shelf heating
Heraeus®vacutherm®6000 BL Vacuum Drying Ovens for safe drying of samples that contain flammable solvents offer a unique safety concept that, even in the case of unsupervised operation, provides optimum protection.
Safety concept
■ Meets the requirements of
Explosion Protection Guidelines
■ Pressure related activation of
the heating elements
■ Precision control valve allows
inert gas operation
■ Forced release of inertgas in
case of an accidental increase in pressure
Safe, user friendly operation
The VT 6000 BL’s safety concept has no limitations to working tem­peratures. Elaborate calculations of working temperature – due to the composition of solvents are therefore not required.
Technical data
The vacutherm®6000 BL technical data are identical to those of the vacutherm®6000 series, see table on page 6.
Features:
■ Rated temperature of
200 °C/300 °C
■ TÜV and GS tested
■ Total volume of 53 and 128 l
(25 l on request)
Additional features
In addition to the standard version described before all ovens also feature a forced release of inertgas system which, in the event of a leakage, prevents the formation of explosive mixtures inside the vacuum chamber. Furthermore the heating elements are only activa­ted oncethe pressure inside the vacuum chamber is below 80 mbar.

Pressure related activation of heating at < 80 mbar. Forced release of inert gas of the vacuum chamber in the case of accidental increase of pressure above 130 mbar.
Permanent ventilation of the control panel area through two indepen­dently operating fans, to prevent solvent leakage.There is no need of permanent feed with gas.
Inert gas connection for gentle ventilation and for operation with process gases.
Double pane door made of safety glass.
Tested implosion protection of the double pane sliding door, in accordance with GS approval.
