Vacuum Heating & Drying Ovens

Hereaus Vacuum Ovens

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 a wide range of equipment options.

Advantages of Hereaus Vacuum Ovens

Product Image (Main)

 

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.

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.

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

Features:

  • Modular design
  • Two types of heating
  • Temperatures to 200, 300 and 400 °C
  • Total volumes of 53 and 128 l

Standard features:

  • User friendly Kelvitron® t microprocessor controller for jacket heated ovens and Digicon® multi-channel controller for shelf heated ovens
  • Upper limit cut-out for oven and product protection
  • Certified safety (GS-mark)
  • Vacuum chamber made of stainless steel (1.4571), electropolished, 100 % rounded corners, easy-to-clean and corrosion resistant
  • Stainless steel vacuum fittings, tubing and ball valve
  • Analogue pressure display
  • Rapid ventilation valve for quick ventilation of the chamber
  • Additional precision valve for gentle ventilation
  • Inert gas connection for controlled atmosphere. A safety valve prevents overpressure inside the vacuum chamber
  • DN 25 access port in the rear wall
  • 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.
