EcoFlex90+ - 90% Boiler Efficiency without Boiler Replacement
 EcoFlex 90+ - a packaged modulating fan-powered economizer – may be the single design that combats all the challenges in the typical economizer. It opens the energy recovery up to practically any combustion appliance application.
With the EcoFlex 90+ system the designer can now view the application as a complete "boiler plant" as the full load to work with, instead of one economizer per boiler. And the "boiler plant" can consist of a combination of boiler types such as forced draft boilers and atmospheric water heaters that utilize a single modulating demand-controlled economizer. The bottom line is: design flexibility, reduced emissions, improved boiler efficiency, high return on investment.
