- 20-gallon capacity to handle significant system expansion volumes
- Maximum operating pressure of 100 PSI for safe, code-compliant operation
- Maximum operating temperature of 240°F, suitable for high-temperature hydronic systems
- Heavy-duty butyl diaphragm separates system water from the air charge, preventing waterlogging
- Durable steel shell construction for long service life
- Pre-pressurized at 12 PSI from the factory for fast, hassle-free installation
- Designed specifically to absorb hot water expansion in closed heating systems
Why Use an Expansion Tank?
In a closed hydronic heating system, water expands as it heats up. Without an expansion tank, this pressure increase can damage boilers, pipes, and fittings, or cause relief valves to discharge unnecessarily. The XPS-040V provides a dedicated air cushion that safely accommodates this expansion, protecting the entire system and extending equipment life.
