The two-stage VHX Flue Gas Economizer can help you conserve that little extra energy compared to the single stage versions.
It 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, ablong 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.
Ruggedly built high-temperature exhaust fan designed for inline mounting or termination mounting for small and large applications. For vertical or horizontal installation indoors or outdoors.
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.
