The MFPE modulating fan-powered economizer (fka IPVB-ECO) is a mechanical draft fan that integrates a flue gas economizer. It is used in conjunction with any type of gas-fired boilers and water heaters where heat recovery is desired. It is installed in the chimney flue system where it can be exposed to the hot flue gases and still ensure a mechanical draft (negative pressure) in the entire chimney or stack system. For optimal performance the fan speed can be controlled by a modulating pressure control (EBC 12 or EBC 30/35).

The MFPE SS is for use with condensing and noncondensing appliances at flue gas temperatures of max. 575°F (302°C). Typical uses are: heat recovery from gas-fired boilers and water heaters. For indoor installation.
The MFPE is typically used in applications with a single modulating heating appliance or with multiple heating appliances utilizing a single chimney flue. It is extremely suitable for low-to-mid efficiency boilers equipped with a draft hood or a draft diverter. These units can not utilize a flue gas economizer without mechanical draft.

The MFPE SS Fan-Powered Economizer is an efficient, high-temperature boiler exhaust fan with backward-inclined impeller. The stainless steel fan housing is equipped with an energy-efficient, totally enclosed, variable speed motor, which is mounted outside the air stream. The design is a Type B, Spark Resistant Construction. The motor and impeller is a complete assembly (drive unit) that can be removed from the fan housing without removing the fan from the stack system. The stack connections are flanged and fit most commercial pre-fabricated chimney systems.

The stack economizer is an integrated part of the fan housing placed on the inlet side. The economizer is thermal counterflow design to assure the highest possible heat recovery. It can be removed through an access panel for easy serviceability.

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.
And what is even better – all boilers will always have the perfect draft conditions due to the variable speed boiler fan controlled by a modulating fan controller.
The bottom line is: design flexibility, reduced emissions, improved boiler efficiency, high return on investment.
