Introducing Series MX40 & MX4010

Atlanta, Georgia, January 14, 2019 — At this year’s AHR Expo, Maxitrol Company revealed its new Series MX40 and MX4010 discharge air temper­ature control systems.

The Series MX40 and MX4010 are used with the Exa E42, E52, and E62 series modulating gas valves.

The MX4010 control system is for use with split manifold atmos­pheric indirect fired heaters.  The split manifold operates as two independent manifold sections sharing a single inducer.  The controller senses and maintains a constant discharge air temper­ature by modulating one section of the manifold and staging the non‐modulating section.  Typical appli­ca­tions achieve a turndown of approx­i­mately 10:1 during continuous operation.

For use with atmos­pheric indirect fired heaters using a 2‐stage inducer, the MX40 senses and maintains a constant discharge air temper­ature by modulating the gas flow and staging the inducer.  Typical appli­ca­tions achieve a turndown of approx­i­mately 5:1 during continuous operation.

Series MX40 and MX4010 consist of either an A40 Amplifier (for 5:1 Turndown) or A40‐SM2 Amplifier (for 10:1 Turndown).  Common compo­nents to both systems are a mixing tube and discharge air temper­ature sensor, and an optional remote temper­ature selector.
