Systèmes utilitaires Cleanroom
Tank de stockage WFI par
An insulated, drainable 316L stainless steel vessel for buffering Water for Injection in hot or periodically heat-sanitized recirculating systems.
- Hot-WFI-ready insulated construction
- Drainable 316L contact surfaces
- Heated venting and sanitary instrumentation
Introduction de produit
The WFI storage tank maintains useful system volume between generation and a continuously circulating distribution loop. Its drainable vessel geometry, hygienic internal finish and spray-cleaning arrangement reduce retained water, while insulation and a stainless outer jacket support hot storage or thermal sanitization strategies. Level and temperature instruments coordinate generation, recirculation and utility control without introducing unnecessary wetted branches.
Key Features
Insulated shell with cleanable stainless outer jacket
Drainable dished bottom and low-point outlet
Heated hygienic vent-filter housing option
Internal spray device for defined wetting coverage
Sanitary level and temperature instrumentation
Side manway for controlled inspection access
Support legs arranged for outlet and piping clearance
Préoccupations du client produit
WFI storage must preserve hygienic conditions while managing temperature, air exchange, changing demand and full-system sanitization.
Stored WFI loses temperature during low demandSpecify continuous loop circulation with correctly sized insulation and a jacket or external heat exchanger matched to the thermal strategy.
Condensation compromises the vent-filter assemblyUse a drainable heated vent housing and controlled steam or electric tracing to keep the filter within its intended operating envelope.
Residual water remains in the tank after drainingCombine a dished bottom, central low-point outlet and drainable instrument branches with the installed vessel orientation.
Generation cycles do not follow plant demandUse continuous level measurement and independent alarm switches to coordinate still output, loop pump protection and operating reserve.
