Closed Expansion Tank
The Closed Expansion Tank from HNL Global Group is a Korean-made solution designed to replace open expansion tanks in heating, cooling, and hot water systems. It prevents pipe corrosion by fully intercepting air contact with water, maintaining system pressure to absorb and restore expansion water without loss. The tank is engineered for installation in diverse locations, from basements to rooftops, with an operational temperature range exceeding 100°C, making it suitable for medium or high-temperature water systems.
Constructed with a fabricated steel shell as per ASME Section VIII, Div. 1, the tank features a butyl rubber bladder and is available in tank volumes ranging from 40 to 5000 litres. Design pressure options include 125 psiG (862 kPa), with higher pressures up to 300 psiG (2068 kPa) available. The design temperature is rated at 240°F (116°C). The system requires no maintenance, with a semi-permanent lifespan for the tank and membrane, and offers energy savings by eliminating heat loss.
This expansion tank is ideal for industrial and commercial applications where pipe longevity and system efficiency are critical. Buyers typically include HVAC contractors, industrial plant operators, and building service engineers. The tank’s ability to maintain pressure without water loss or evaporation makes it a cost-effective choice for long-term installations. Confirm compatibility with existing systems and pressure requirements before ordering.

Sourcing Closed Expansion Tank from HNL Global Group - South Korea Import Guide
Before ordering, verify the tank’s compatibility with your system’s pressure and temperature requirements. Confirm the design pressure and volume capacity match your operational needs, and ensure the ASME Section VIII, Div. 1 certification meets local regulatory standards. Request the supplier’s technical data sheet for detailed specifications.
Logistics details such as lead time, Incoterms (e.g., FOB or CIF), and packaging should be clarified with HNL Global Group. The supplier is based in Seoul, so factor in shipping costs and transit times from South Korea. Confirm whether the tank is shipped pre-pressurized or requires on-site filling and pressure testing.
For quality assurance, inspect the tank upon delivery for compliance with ASME standards and the specified material construction. Check the butyl rubber bladder for defects and ensure all fittings and connections are intact. Request a test certificate or third-party inspection report to validate the tank’s pressure and temperature ratings before installation.
