Boiler Heat Recovery and Energy Savings TRUE GREEN SOLUTIONS Modulating Fan-Powered Economizer with By-Pass

ENERVEX - Quality Energy Savings and Efficiency Over the years, improvements have been made to economizers that now have better heat transfer rates than ever, but it is still only very few boilers that can benefit from their installation. Atmospheric and fan-assisted boilers don’t create a powerful draft that can force flue gases through the economizer which make them unsuitable for economizer installations. In a typical 5,000 MBH atmospheric heating boiler system used in schools, hospitals and hotels/resorts, the radiator design is far more efficient than the traditional economizer over...

Energy and Operating Savings – Ultra Short Payback with Great ROI! There are many ways of taking advantage of the EcoFlex 90+ System’s ability to recover energy, save installation cost, and reduce emissions. Below are examples of possible savings. The two typical system examples both consist of 2 x 1,500MBH and 2 x 750MBH atmospheric boilers – 2 with draft hoods and 2 with barometric dampers. The systems operate 4,000 hours per year – 600 hrs at full capacity, 2,000 hrs at 50% capacity and 1,400 hrs at 25% capacity. Georgetown Brewery - Seattle, WA Less than 1 year Payback!

EcoFlex 90+ - The Complete System Overview The main system component is a true inline high-temperature, variable speed exhaust fan (TDF) with an integrated heat recovery module (VHX) and EBC35 Exhaust Rate Controller. Both the fan and the heat recovery module is made in 316L stainless steel, so it can be used with virtually any type of exhaust application. Together, the components support design flexibility, reduced emissions, improved heat recovery and high return on investment in a short period of time. The VHX and TDF can be supplied with a tapered inlet and a straight outlet or with...

VHX Heat Exchanger High Capacity Economizer The Vortex Heat Exchanger, Model VHX, is a revolutionary economizer that addresses the real world need for an efficient economizer with a built-in bypass. The heat exchanger is mounted on an internal rail system that allows it to easily slide in and out for service or cleaning. With its construction in 316L stainless steel, it can be used for both condensing and non-condensing applications.

Any way You Want it! The EcoFlex90+ System concept is a huge leap forward for the energy and cost conscious engineer and building owner. It is possible to install the heat recovery unit in virtually any boiler system – new installation or retrofit, single or multiple appliances, modulating or on-off boilers, condensing or non-condensing boilers. System consisting of an existing forced draft boiler and an atmospheric water heater. The EcoFlex 90+ System is installed inline in the common horizontal section – but could also have been installed in the vertical section. System consisting of...
