Capable of providing steam within 5 minutes, Circulatic incorporates link-free controls and communications capabilities. The controls offer improved combustion, fuel savings and increased reliability due to the elimination of mechanical linkages. Other features include a compact design and full modulation with 10:1 turndown ratios.
The forced recirculation watertube boiler uses a drum as a steam separator and a reservoir of water to supply the coils. A recirculating pump draws the water from the drum and forces it through a set of parallel connected coils at the rate of three to four times the maximum steaming rate.
