Efficiently manage thermal expansion and stabilize system pressure in your hydronic loops with the Wessels NTA-20. This high-performance ASME-rated expansion tank is engineered to handle the demands of commercial heating and cooling applications, ensuring consistent performance and system longevity.
The unit utilizes a heavy-duty internal diaphragm that isolates the system water from the tank shell. This design prevents internal corrosion and eliminates common water-logging issues, making the NTA-20 fully compatible with water and glycol-based mixtures.
Key System Performance Baselines:
- ASME Certified: Built to meet strict pressure vessel standards for reliable operation at 150 PSI.
- Diaphragm Design: Heavy-duty bladder effectively manages expansion while preventing oxygen infiltration.
- Corrosion Protection: Internal construction minimizes the risk of tank oxidation, extending the service life of the vessel.
- Media Compatibility: Engineered to function seamlessly with standard water and glycol heating/cooling mixtures.
⚠️ Application Profile: Ideal for commercial boiler rooms, large-scale radiant heating systems, closed-loop chilled water distribution, and multi-zone hydronic HVAC infrastructures requiring Cal Code compliance.
