The enclosed filtration system Hermetix from Strassburger Filter is designed for the demands of the pharmaceutical industry. The enclosed multilayer filter uses depth filter sheets for filtration. The filter plates are sealed by circumferential O-ring gaskets on the filter plates and the internal filter layers. This results in 100 % sealing without leakage. All contact with the product’s surrounding environment is eliminated. The system distinguishes itself by easy handling and the possibility of CIP cleaning. The required filter area can be flexibly adjusted by the size and number of filter plates. A large selection of filter aids enables the safe separation of solids and microorganisms. High yields and drip losses are of utmost importance for the economic efficiency of processes in the pharmaceutical sector. The Hermetix filter press was designed with a hermetically sealed filter plate package to meet these requirements. Without drip losses and with maximum yield. The special design allows the Hermetix filtration system to be completely emptied.
