Dynaforce

The Dynaforce has an efficiency rating of up to 99% and features a vertical cylindrical heat exchanger which is constructed entirely of stainless steel. The Dynaforce is available for Hydronic Heating or Domestic Hot Water supply and can be fired with either natural gas or propane. Models range from 300,000 BTU up to 5 million BTU with a turndown ratio of up to 5:1.

• 18 models available
• Inputs ranging from 300,000 btu/hr to 5 Mil btu/hr
• Up to 99% Thermal Efficiency
• Suitable for Category 2 and Category 4 installation
• Welded heat exchanger, 316L headers, 439 tubes & counter flow
• Return water temperatures down to 40°F

Control Panel Highlights:

The Dynaforce is controlled by an integrated Honeywell SOLA controller. The 7” color touchscreen provides remote operation through the 4-20mA or 0-10Vdc for set point or fire rate control. Paired with the ability to control multiple pump operation along with daisy chain setup for up to 8 boilers. This user friendly control also provides you with a USB output for screenshot capture as well as password access for service personnel.
