Vacuum Heating and Drying Ovens

Vacuum Heating and Drying Ovens VHT Series
Optimum drying results under exceptional conditions

The Advantages

No doubt, there are various ways of drying your product with each process having its advantages and disadvantages. So why should you decide on the vacuum drying process?

Our vacuum drying ovens provide you with the following advantages:
- Heat sensitive mediums (e.g. pharmaceutical products)
- Reduced drying times by lowering the pressure
- Due to the extremely low remaining oxygen content in the drying oven there are no oxidation processes
- Evaporating fluids (e.g. solvents) can be recovered
- Optimum drying conditions for light, powdery products as there is no turbulence (no convection)
- No "skin-forming" on the product being dried; therefore constant drying performance
- Economic because steam or warm water from other processes can be used as a heat medium
- Flexible heating

Heating Modes

Temperature Range

- Electrical
- Warm water
- Thermal oil
- Steam
- Infrared radiation

The maximum rated temperatures that can be reached at the product being dried depend on the mode of heating used for the drying oven.

Mode of Heating - Max. Temp. Celsius

- Electric - 200/400
- Warm water - 95/140
- Thermal oil - 200/250
- Steam - according to steam pressure

Control

Our vacuum drying ovens are equipped with a digital microprocessor controlled system.

The electric heating enables you to:
- Control and monitor each shelf individually
- Set the drying times
- Perform the drying process program-controlled; with one of 99 programs
- Connect a PC (via RS 232 or RS 485 interface)

When using a heat transfer medium you can control and monitor the temperature of the medium.
