Stainless Steel Tanks
The rapid growth of data centers is increasing the demand for stainless steel hydronic equipment that can handle continuous operation and challenging water conditions. As systems become larger and more critical, operators are prioritizing materials that offer superior corrosion resistance, durability, and long-term reliability. Stainless steel tanks and components, often designated as SS- Series, are well suited for these environments where performance and system protection are essential.
Wessels Company supports this need with a range of stainless steel products designed for high-performance applications. SS-WVA and High Velocity (HV) air and dirt separators remove entrained air and particulate that can cause noise, reduce efficiency, and damage system components. Stainless steel air purgers and separators use internal flow patterns to efficiently eliminate air, helping maintain quiet and stable operation while protecting equipment from corrosion. These solutions are especially valuable in systems using glycol or treated water where material integrity is critical.
Maintaining water quality is also a key concern in data center cooling systems. WesFlo bag and cartridge filtration vessels provide high-efficiency particulate removal to keep systems clean and operating at peak performance. Together with stainless steel expansion tanks, storage, buffer, and separation equipment, these products help ensure reliable operation, reduced maintenance, and long service life in the most demanding commercial and industrial applications.
