Xylem-Bell & Gossett 116302 D-80 45 Gallon ASME Pressure Expansion Tank

The Xylem-Bell & Gossett 116302 is a D-80 series ASME-rated pressure expansion tank designed for commercial and industrial hydronic heating and cooling systems. With a 45-gallon capacity, this expansion tank accommodates thermal expansion in closed-loop systems, protecting boilers, water heaters, and piping from excessive pressure buildup.

Key Features:

• 45-gallon total volume capacity for larger commercial applications
• ASME-certified construction for high-pressure applications up to 150 PSI
• Heavy-duty steel construction with corrosion-resistant coating
• Butyl diaphragm separates system water from air charge, preventing waterlogging
• Pre-charged air cushion absorbs thermal expansion efficiently
• Designed for potable water, hydronic heating, chilled water, and solar thermal systems
• Top and bottom connections for flexible installation options
• Replaceable bladder design for extended service life

The D-80 series tanks are engineered to meet the demanding requirements of commercial HVAC systems, providing reliable pressure control and system protection. The ASME certification ensures compliance with building codes for commercial installations requiring certified pressure vessels.
