Please welcome a new member to our Engineering department: Zach Pokrzywinski. Zach joined the Wessels family in December of 2025 as a design engineer and says his favorite thing about the new job is being able to create tanks with great people. In his spare time, he enjoys playing video games, playing and watching sports, and working out. He also loves rooting for the Pittsburgh Steelers.
Are You “Tanking” Advantage of the Data Center Gold Rush?
Data centers are in a full-tilt gold rush and the winners are the ones “tanking” advantage of smarter HVAC design. With nonstop thermal loads and tight efficiency targets, system stability matters more than ever. Wessels TES thermal energy storage tanks allow operators to shift cooling to off-peak hours, smooth out fluctuations, and gain valuable capacity without oversizing chillers. When paired with Wessels buffer tanks and high-pressure bladder expansion tanks, chilled water loops maintain steady performance and protect uptime.
Reliability is equally critical in mission-critical environments. Wessels SS-AP stainless steel air purgers remove damaging entrained air that can disrupt pumps and reduce overall performance. Stainless construction options throughout the product line support glycol and strict water quality requirements in modern data center designs. From TES tanks that shave peaks to SS-AP air management that keeps systems clean and consistent, Wessels helps data centers turn HVAC infrastructure into a competitive advantage.
Thermal Energy Storage Tanks
Wessels TES Thermal Energy Storage Tanks are designed to store thermal energy for cooling data centers, renewable energy applications, loss of power, or delivery during off-peak hours. The tanks feature dual inner-screen WesPro Super Baffle Systems to stratify and reduce the thermal mixing zone (thermocline), increasing the delivery efficiency of hot or chilled water.
Low water volume systems require additional “buffer energy” capacity to eliminate problems such as excessive equipment cycling, poor temperature control, and erratic system operation. The TES Tank adds the necessary volume to “buffer” the system volume.
Air Purgers
In-line Air Purgers are used for commercial and industrial hydronic systems, to effectively control and eliminate entrained air.
The SS-AP Series air purgers:
- Rated to 450°F and 150 PSI
- Designed with an embossed flow indicator arrow for proper installation.

Wessels Company Breaks Ground on New Factory in Ohio

FOR IMMEDIATE RELEASE
Wessels Company Breaks Ground on New Factory
TIFFIN, OH. – Wessels Company is pleased to announce the construction of a new factory at its Tiffin location, which will be leased by the parent company National Machinery Group Global LLC to Wessels East for a major expansion of its pressure vessel manufacturing operations. The new facility will join the existing National Machinery space at the corner of Greenfield and Holmes streets in Tiffin, Ohio. Projection date for completion of the building and beginning manufacturing is November 2025.
The 57,000+ sq ft facility will be situated in the southeast corner of National’s Greenfield Street campus. An attached building on the east side of the factory will provide office space and restroom facilities. Construction of the manufacturing facility is scheduled to be completed by Q4 of 2025. Wessels intends to hire a dozen new employees within the first few months of opening the new facility and nearly 30 more next year as a second shift is added in the following year.
Wessels’s core products are hydronic HVAC pressure vessels of various sizes built in accordance with ASME standards. The headquarters and main plant are in Greenwood, IN, just south of Indianapolis. The original Wessels East facility launched in Bay 1 of National Machinery’s factory in 2007, expanding production capacity for oversized tanks beyond the capabilities of the Greenwood plant. These larger tanks are typically 48” to 72” in diameter, but the new facility will allow for even larger specifications. Wessels management sees tremendous opportunity to capture more business in this large tank market, in part propelled by the boom in the construction of data centers, which must be kept cool with specialty equipment like Thermal Energy Storage (TES) tanks.
