MLH Series Micro Line Heater

Brand: Thermon Cata-Dyne™
Does not ship to Virginia, United States

The Cata‑Dyne™ Micro Line Heater prevents equipment freezing and possible hydrate formation during pressure reduction at natural gas regulating sites.

The Micro Line Heater heats the gas stream using infrared radiant heat transfer, eliminating the use of burners, glycol fluid and high maintenance heat exchange systems. Custom engineered units for nonstandard applications are available.

The Cata‑Dyne™ Micro Line Heater's use of direct infrared heat transfer eliminates the need for traditional gas fired glycol bath systems. The elimination of glycol based heat transfer systems results in a more environmentally favourable installation.

High field maintenance and operating costs are all eliminated by the Cata‑Dyne™ Micro Line Heater.
