When properly implemented, the double-row ENERVEX Flue Gas Economizer VHX-DR can help you conserve energy and save 10+% on fuel annually.
This is a highly versatile and efficient flue gas economizer for single OR multiple boilers of atmospheric, fan-assisted, or forced-draft design. Its fully packaged, lightweight, round configuration, integrated modulating bypass, and efficient hybrid microchannel/plate heat exchanger allows extremely high heat transfer capability and low flow resistance.

The HMM heat-module manifolds are used in conjunction with the VHX Economizers. They are used to connect the heating on the supply and return sides.
A mid-range high-temperature mechanical draft fan designed for inline mounting. For vertical or horizontal installation. Used with condensing or non-condensing heating appliances.
A totally integrated heat recovery control system that monitors inlet and outlet water and flue gas temperatures to maintain the outlet water temperature you need, while maximizing heat waste recovery and efficiency.
A sophisticated multi-use draft and pressure controller with integrated webserver and remote access used with fans and dampers to monitor and maintain a constant pressure in commercial boiler and building applications.
