FAQ

Why choose Stainless steel instead of polyethylene?

Stainless steel AISI 316L provides chemical resistance, hygiene, and PW/WFI water compatibility; polyethylene, while useful, does not reach these standards.

Do the tanks support CIP/SIP?

Yes, they are prepared for CIP/SIP washing systems compatible with purified water and water for injectables.

What certifications are included?

Each tank is certified according to PED Directive (2014/68/EU) and accompanied by IQ/OQ documentation, FAT and SAT.

Can it be integrated with an automation system?

Certainly: provision for PLC/SCADA systems with transmitters, valves and real-time monitoring.
