Fluidic applications carried out in tanks – like fermentation or storage – often require the precious media to be protected from reacting with air, oxygen and other ingress. A pressurised inert gas layer above the media serves to maintain a stable chemical balance. This process is known as tank blanketing and commonly utilised in pharmaceutical and biotechnology industries. Building upon the new hygienic control valve Type 2380 , a truly robust system is in charge of increasing safety levels in tank blanketing and many more demanding applications.

Although a seemingly simple process on the surface, the strict requirements with respect to cleanability and cross-contamination prevention – mandated by the highly regulated pharma and biotechnology industries – introduce a new level of complexity to this application. Standard off-the-shelf components typically used for tank blanketing inherently cause issues with cleanability, are highly susceptible to contamination and can result in risk issues an erratic failure rates due to naturally acidic carbon dioxide or other aggressive foam upon exhausting. They are simply not fit-for-purpose.
Downtimes, maintenance costs and comprise of product quality are all risks introduced by utilizing the common standard solenoid components.
