EM - Energy Manager Boiler Economizer Series
Built to rigid ASME quality control standards
The EM (Energy Manager) is designed to recover heat from combustion sources with atmospheric burners from 200 to 6400 MBH. By utilizing the flow control valve the EM effectively reduces the stack temperature to 250°F or lower (adjustable with the differential pump control as the burner cycles). Ten standard models are designed to operate with low static gas pressure drop for safe, automatic operation on atmospheric, or power burners.

EM Model Selection
The following model selections are determined by stack diameters and BTU/hr input using this simple selection chart. After the correct Energy Manager has been selected, contact your Cain representative to determine your fuel savings and provide a complete proposal with payback period. Stack diameters smaller than standard EM sizes can be accommodated simply with a pair of EM Model to Stack Transitions.
