Dec offers a range of small PTSs for transporting small quantities of powder with chamber volumes typically between 10g and 200g. The principle of operation is based on PTS technology. The MPTS can be used either to load small quantities into process equipment such as a reactor, or for in-process sampling. The MPTS is very compact and can be easily installed on small equipment such as a glass reactor for a pilot or kilolab plant, or it can be integrated into an isolator. The system can be easily disassembled and can be made for CIP, can be used in sterile conditions. The MPTS can also be supplied with an adjustable chamber for volume dosing.

The patented PFL Powderflex provides continuous and accurate dosing of small to medium quantities of powder, whether controlled loading of powders in continuous production processes or dosing of predetermined accuracy is required. This technology was originally developed for plasma and spray coatings, but is currently used in many areas. PFL extracts powder from any container and transports it over long distances. Its simple design ensures minimal maintenance, making it easy to quickly replace the product. The characteristics of the powder during transfer do not change. PFL is to powder what a peristaltic pump is to liquids. The system consists of two small calibrated chambers, each equipped with a flat filter at the top. A virtually continuous powder flow or precise volumetric dosing is ensured by a unique valve system. The combined action of vacuum and pressure alternately fills and empties the chambers at high frequency. The transmission rate can be easily adjusted by changing the chamber volume or changing the frequency.

The PTS Powder Transfer System® is a vacuum and pressure based powder transfer system that eliminates the need for gravity unloading. The unique technology allows the transport of powders with different characteristics.
PTS not only provides complete process isolation, but also saves time. The principle of operation ensures that there is no product segregation and particle damage during transfer, and eliminates the risk of electrostatic charge buildup.
The design of the PTS allows CIP/SIP cleaning and sterilization.
More than 5,000 PTS systems are in use worldwide for applications ranging from loading reactors to unloading centrifuges or packing powders in highly isolated environments.

The MPTS can be provided as a portable version to take samples from different equipment at different locations. The control panel and MPTS are mounted on a trolley, and the flexible powder hose can be directly connected to the sampling equipment. The system only needs to be connected to vacuum, compressed air and, if required, nitrogen if sampling is to be carried out in an inert atmosphere.

Primary Sealing OEB 3-4 Storing chemicals and API products in bags or sleeves is standard practice. In the manufacture of pharmaceutical products, sleeves must have special properties to prevent contamination of the product. Separate bags should not be used to ensure GMP compliance and internal filling of bags or sleeves as both product and operator may be exposed during bag removal and replacement. To prevent the use of a complicated protective casing, the CLS Continuous Liner System is an elegant and economical solution.
