Altech 18L Expansion Tank

An expansion tank designed to absorb excess pressure and volume changes in closed heating and hot water systems. The ALTECH 18L expansion tank helps protect piping, pumps, and radiators by stabilizing system pressure during thermal cycles.

Key advantages

Reduces pressure fluctuations and prevents water hammer in heating systems
• Protects boilers, pumps, and valves from stress caused by thermal expansion
• Compact capacity suitable for small to medium domestic and light commercial systems
• Simple installation and low maintenance compared to open systems
• Extends service life of heating equipment by maintaining stable pressure

Application and use cases

Suitable for use wherever thermal expansion needs to be managed in closed-loop systems. Typical applications include domestic and light commercial heating installations and hydronic circuits.

Domestic central heating systems to control pressure changes
• Closed-loop hot water systems in homes and small apartments
• Boiler systems to reduce cycling and extend equipment life
• Small commercial premises with hydronic heating

What to consider when choosing

Match the expansion tank capacity to the system size and expected expansion volumes
1. Ensure compatibility with system pressure and connection types used in your installation
2. Consider placement and space availability for installation and maintenance access
3. Check for quality of materials and manufacturer reputation when evaluating price vs value
