Features
- ASME certified pressure vessels
- Available in two and four-port (primary-secondary) configurations
- Three sizes: 104 gallons, 210 gallons or 289 gallons
AERCO buffer tanks are ASME certified pressure vessels designed for use with high efficiency, low volume systems that incorporate low-mass condensing boilers. They add thermal mass, dampen fast transitions and minimize boiler cycling that occurs during zero or low domestic load conditions. The AERCO buffer tanks are available in two and four-port (primary-secondary) configurations.
Features and Benefits
- Vertical orientation promotes natural stratification
- Connections for air vent and drain
- One-year limited warranty against failures resulting from defects in material and workmanship
- Available in three sizes: 104 gallons, 210 gallons, or 289 gallons
