CiK Solutions offers a wide range of vacuum dryers. Choose among different models ranging from 8 liters to 130 liters in volume. All models of our Kambic vacuum dryer series are very easy to use, extremely reliable and very durable.
Kambic Vacuum Dryers
We offer high-performance dryers in three chamber sizes with a maximum operating temperature of 200 °C. If required, this range also provides the base models upon which a variety of custom modifications can be made.
Vacuum drying is the transfer in which the moisture present in a substance (usually a wet solid body) is removed by vacuum generation. In the chemical process industries such as food, pharmacy, agriculture, textile, paper & pulp, and many others, drying is an essential requirement for the removal of moisture.
Vacuum drying is generally used to dry hygroscopic and heat-sensitive substances and is based on the principle of creating a vacuum that lowers the pressure to below the vapour pressure of the water. Using vacuum pumps, the pressure around the material to be dried is reduced. This reduces the boiling point of the water inside the product and thus significantly increases the evaporation rate. The result is a significantly increased drying rate of the product.
In the pharmaceutical industry, the vacuum dryer is known under the common name vacuum oven. The oven door is hermetically sealed by a high-quality silicone gasket and connected to a vacuum pump to reduce pressure.
Besides Vacuum Dryers, we also offer Drying/Warming ovens and Freeze Dryers.

The key factor in vacuum drying is to ensure the correct vacuum. Many different types of vacuum pump are available to achieve this for specific drying purposes. In practice, for the majority of the time we deal with only two types of pumps:
Characteristics of the oil vacuum pump, suitable for use in our dryer:
|Final vacuum:||10-2 mbar|
|Number of stages:||2|
Oil vacuum pumps are the most frequently used types and the most favourable in price. They can easily achieve a vacuum as low as 1 mbar, sometimes even lower. They are robust and very durable if properly maintained, however, there are some drawbacks. Oil vacuum pumps are usually not chemical-resistant, making a steam condenser necessary when used for drying aggressive media. Otherwise, these aggressive media can damage vital parts of the pump, the oil quality can drastically deteriorate, requiring a regular change of oil and the pump will require more frequent cleaning.
Characteristics of the chemical resistant vacuum pump, suitable for use with our dryer:
|Final vacuum:||2 mbar|
|Number of stages:||3|
This pump is chemical-resistant and enables aggressive media to dry, as it is 'dry-running' and does not use oil for lubrication. This considerably extends the maintenance intervals. The membrane pump has a standard, in-built glass liquid collector on the exhaust duct, which prevents the condensed liquid from entering the pump. There is also a pair of in-built insulated glass condensers on the exhaust side, which can be cooled with water, and thereby providing efficient condensation and collection of exhaust fumes.
No oil lubrication also means no oil fumes left in the exhaust. Despite the multi-stage construction, the vacuum can reach down to 2 mbar.
