Stainless Steel Large Sterile Water Tank – Dished Head Series (0.5T – 20T)
Stark Large Sterile Water Tank (STK2 Series) features a reinforced Dished Head design for superior structural integrity. Available in capacities from 0.5T up to 20 Tons (20,000L) with heavy-duty 3.0mm wall thickness, it is the standard for centralized aseptic storage in pharmaceutical and food industries.
Product Description
Structural Integrity for Bulk Aseptic Storage.
When storage requirements exceed 5 tons, standard conical tanks may not withstand the hydrostatic pressure. The Stark STK2 Dished Head Series utilizes an industrial-grade Torispherical/Elliptical head design. This geometry distributes internal stress evenly, allowing for the safe construction of massive vessels up to 20,000 Liters.
For models 5T and above, we upgrade the wall thickness to a robust 3.0mm, ensuring maximum durability while maintaining a sanitary mirror-polished interior for contamination-free storage.
Foundation Load & Dimensions:
Installing large tanks requires precise structural planning. For full load-bearing data, leg footprint drawings, and wind load calculations for outdoor installation, please reference the technical data at our manufacturing division:

Applicable Industry
- Centralized Pharma Water Systems:
Acts as the central storage hub for Purified Water (PW) distribution loops in pharmaceutical parks. 20T capacity reduces the need for multiple smaller tanks. - Beverage & Dairy Processing:
Large buffer tanks for mixing or storing raw ingredients. The dished head ensures easy cleaning and structural safety under agitation. - Municipal & Emergency Supply:
Aseptic bulk storage for hospitals or critical facilities requiring an emergency reserve of potable, sterile water.
Advantage One
Dished Head Structural Strength
The Torispherical (Dished) Head is the hallmark of high-pressure industrial vessels. Its curved geometry eliminates the stress concentration points found in flat or conical tanks.This allows the STK2 series to maintain its shape and integrity even when fully loaded with 20 tons of liquid, providing a safer, longer-lasting storage solution.Advantage TWO
Mega Capacity Range (Up to 20 Tons)
Designed for scale, this series offers storage capacities from 0.5T up to 20T.By consolidating storage into a single large vessel with a small footprint (relative to volume), facilities can simplify their piping networks, reduce control valve points, and lower overall maintenance costs.Related Products
