Round Expansion Tank Bracket

Round Expansion Tank Bracket Series for Water Heater & Hydronic Systems

The Easywell Round Expansion Tank Bracket Series delivers balanced strength, precision fit, and corrosion resistance for all types of expansion vessels used in residential, commercial, and industrial heating systems.
Each bracket is engineered for quick installation, heavy-load stability, and long-term resistance to temperature and vibration.

With variants from standard steel D42 models to corrosion-resistant industrial kits, Easywell provides reliable solutions for every hydronic configuration.

Why Choose a Round Expansion Tank Bracket?

• Precision Round Clamp Design – Ensures perfect contact with cylindrical expansion tanks, minimizing stress and vibration.

• Quick-Mount System – Adjustable bolt positions and pre-drilled wall plates simplify installation on any wall or manifold.

• High-Strength Construction – Heavy-duty steel with zinc or epoxy coating resists pressure, humidity, and mechanical strain.

• Modular Compatibility – Works with both vertical and horizontal tank orientations across hydronic and HVAC systems.

• All-Weather Protection – Optional epoxy or anti-corrosion finishes designed for coastal, industrial, and renewable installations.

❓ FAQ

Q1. What’s the difference between Round and Bowed expansion tank brackets?

The Round type offers direct cylindrical contact, providing a precise fit for round tanks and a smaller installation footprint. Bowed designs are optimized for high humidity or chemical environments.

Q2. Which Round bracket is best for industrial applications?

Choose Corrosion-Resistant or Heavy-Duty Industrial models for continuous operation above 8 bar or in corrosive air conditions.

Q3. Can Easywell provide custom bracket sizes?

Yes, OEM customization is available for pipe diameter, thread size, coating, and wall flange design.

Q4. Are these brackets suitable for renewable or solar-thermal systems?

Yes, the All-Weather and Modular Hydronic versions are built for outdoor renewable systems and solar loops.

Q5. How do I install the bracket?

Use expansion bolts rated ≥ 10 kg per anchor, seal threaded joints with PTFE tape, and maintain 10 cm clearance below the tank.
