PINK GmbH Thermosysteme

Perfect clean and contamination-free drying processes

GMP/FDA-compliant

The manufacture of sensitive and, under certain circumstances, highly potent, hazardous products calls for plants and systems capable of gently drying such products under extremely clean and contamination-free conditions. The VSD vacuum drying ovens create precisely these conditions.

The VSD is ideal for GMP/FDA-compliant processes. These vacuum drying ovens are an indispensable feature of pilot plants, kilo labs and production installations.
 

Intelligent design for high customer benefit

Together with its elaborate production process, the design principle of the VSD system is responsible for the vacuum drying ovens' outstanding features: no corners, no sharp edges – an interior as from a single mold. The heated shelves, ceiling and floor are double-walled and merge seamlessly into the chamber walls. Due to the system's efficient heat circulation, the walls are also uniformly heated and cannot serve as condensation surfaces therefore.

On the front, the vacuum drying ovens are fitted with a continuous mounting frame for wall installation, the frame being tightly welded to the vacuum chamber. With its pharmaceutical design the door is eccentrically hinged so that the door seal can be perfectly fitted to avoid abrasion and bruising.

System for the prefiltration and drying of liquid, toxic products

As another example of an intelligent combination, PINK combines VSD vacuum drying ovens, isolators and pressure nutsches in integrated systems.

This combination enables the prefiltration of liquid products before the drying process proper, thus optimizing work processes.

For applications in which the filling and filtration of the product is to take place outside the isolator, PINK has designed a mobile pressure nutsch for contamination-free docking.

Dynamic drying system for high-purity and sterile processes

For many applications, it is useful to combine drying with motion. Powders and granulates are mixed during the drying process, thus ensuring uniform heat transfer to the product. In addition, the rotary dryer can be loaded and unloaded contamination-free and with reduced effort. The drum has a dual-cone design.

The efficient system was designed for efficient rotary vacuum drying. Its main advantage over conventional rotary ovens is that the drum of the RTSD has a single rotary joint. This means that the supply of heating medium, measurements, vacuum generation and the drive are all effected via the single rotary penetration. This enables an optimum installation in clean rooms for sterile processes.
