Heat-Module Manifold

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.

Inline Power Venter

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.

Economizer Controller

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.

Modulating Pressure Controller

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.
