PSL will be exhibiting their High Containment Filter Fryer (FilterBox) at Achema in June before it is installed in Helsinn’s new cytotoxic facility in Biasca.

PSL filterbox

Powder Systems Ltd (PSL) supports Helsinn Advanced Synthesis SA’s expansion into the cytotoxic market with their revolutionary contained filtration and drying technology.

 

Helsinn Advanced Synthesis SA (HAS), located in Biasca, Switzerland, is the chemical manufacturing business unit of the Helsinn Group. 

To meet the demand of anticancer molecules, HAS is in the process of building a dedicated cytotoxic facility. The facility will be dedicated to cytotoxic compounds that require safe product handling in a contained area for operator, environment and product protection.

The cytotoxic plant is due to open two production areas in January 2013. PSL will provide two charging gloveboxes with slurry vessels and also two FilterBoxes (Hastelloy pressure filter dryers with high containment).PSL worked closely with Helsinn to develop suitable solutions for their cytotoxic facility and is providing a suite of high containment systems including contained agitated nutsche filter dryers (ANFDs). One of the contained ANFDs produced for the facility will be on show at Achema in June 2012.

PSL’s FilterBox technology:

PSL FilterBox

The FilterBox is the optimum contained filtration and drying solution for handling cytotoxic compounds. The FilterBox allows the following operations to be performed in one unit in a completely contained environment:

–          Filtration and drying

–          Contained sampling

–          Discharging, dispensing and packing

–          Safe and contained base opening and washing

–          Filter mesh inspection and changing

PSL FilterBox

The FilterBox consists of a lab to production size PSL’s filter dryer (0.002m² to 0.3m²) surrounded by a high containment glovebox isolator for the ultimate containment solution. The two FilterBoxes to be installed in Biasca will have a filtration area of 0.125m² and 0.3m².

PSL’s filter dryers are specifically designed for handling potent and cytotoxic products and comprise numerous design features for high performance including:

Even with the efficient CIP and reflux cleaning systems incorporated into PSL’s filter dryer, HAS required higher containment with an OEL test result of <50ng/m³ during the sampling period for their cytotoxic facility 3b category.

PSL’s minimum volume clamp base design, PSL tapered filter plate for optimum seal, full heating jacket to maximise heat transfer, one piece agitator equipped with omega wave bellows and more.

Due to the characteristics of their products, it was crucial that they could open the vessel base completely and manually clean some critical areas in a contained manner. With the FilterBox, the cleaning procedure can be performed safely and thoroughly as the complete vessel base, filtration media and discharge plug can be accessed in a completely contained environment.

The FilterBox will be displayed on PSL’s stand C31, Hall 5.1 at ACHEMA 2012.

Visitors will be able to see a production scale isolator surrounding an ANFD with a filtration area of 0.125m². The filter dryer has a 10kgs product capacity, with 150mm cake depth and an Hastelloy 22 construction. The vessel is designed in accordance with ASME VIII, Div 1, 2010 and operates at a minimum temperature of -25°C and a maximum temperature of 165°C.

Helsinn kindly agreed to provide Achema visitors with an exclusive opportunity to see this revolutionary high containment filtration and drying solution before installation at their new cytotoxic facility in Biasca, Switzerland.
Visit PSL at Achema, Frankfurt in June 2012, Hall 5.1 stand C31, to see the FilterBox and learn more about Powder Systems Ltd (PSL) and Helsinn Advanced Synthesis SA (HAS).
