Commercial Cast Iron Boilers

Advantages at a Glance

• Eliminates the need for bypass loop or shunt pump.
• Eliminates hot and cold spots in the boiler
• Minimizes thermal stresses in each section
• Allows operation at low return water temperatures without thermal shock concerns
• Minimum supply temperature of 122° F with standard control.
• Ensures balanced water flow through all boiler sections

Technology

• Maintain minimum 122º F supply temperature with standard high temperature controls during burner operation within 10 minutes after burner starts up
• No additional requirements for firing with 2-stage or full modulation burners (gas or oil)
• No minimum return water temperature and no minimum flow requirement
• Boiler(s) shall not require return water temperature control or minimum flow condition
