Xylem-Bell & Gossett 116301 D-60 ASME Diaphragm Expansion Tank 35 Gallon

The Xylem-Bell & Gossett 116301 is a Series D-60 ASME-rated pressurized expansion tank with a 35-gallon capacity and 28-gallon acceptance volume, specifically designed for commercial and industrial hydronic heating and cooling systems. This pre-charged diaphragm-type pressure vessel is ASME certified and engineered to handle the demanding requirements of large-scale HVAC applications.

Key Features:

• Designed to absorb expansion forces of heating/cooling system water while maintaining proper system pressurization under varying operating conditions
• Heavy duty diaphragm separates system water from the tank air charge, eliminating water-logging problems
• Built-in bladder integrity monitor with customizable options such as sight glass and seismic restraints
• Constructed with durable carbon steel and integrated pressure-monitoring gauge port
• Engineered to reduce noise and vibration for quiet operation
• Vertical mounting configuration for space-efficient installation

Important: Not for potable water systems. This tank is specifically designed for closed-loop hydronic heating and cooling applications where reliable pressure control is critical to system performance and longevity.
