“The cooperation between PSL and Helsinn was a real success.
The ergonometric, performances and fine-tuning of the containment equipment derived directly from the straight and fruitful communication skills between PSL and Helsinn management. Undoubtedly the most creative and innovative ideas came through long and positive conversations between the project managers of the respective companies.”

“We have had a great working relationship with PSL for 18 years who provided us with Filter Dryers, Milling, Coating Equipment, Blenders and Containment Systems for our comprehensive powder handling facility.

The systems are fully operational today and continue to fulfill our production requirements and although service requirements have been infrequent, whenever we have required assistance with our equipment PSL’s response has always been exceptional.

It is for this reason we continue to purchase innovative equipment offered by PSL.”

Capsugel Logo

“Capsugel’s business demands high standards and this was no different when selecting a specialist containment company to partner in the development of the Xceloprotect™ isolator – a high containment solution for our Xcelodose® precision powder micro-dosing system. The need for a history of sector expertise, and demonstration of understanding and delivering bespoke designs, led us to PSL after a stringent vendor selection process.

The precision of the Xcelodose technology required the design to fully realise all of the sensitivities within the requirements, as well as incorporating a strong equipment family theme.”

Mike Savill, Pharmaceutical Technology Manager, Capsugel, UK
