Submittal Data GA Line AY Series Thermal Modules and Thermal-Links Outdoor Modular Heaters Heating The Robur AY00-119 Heater is supply temperatures up to offering heating outputs up to designed for outdoor 185 °F. Modular heater links, 554,500 BTU/h. These heating installation requiring no mounted on steel rails are systems satisfy larger heating protection from adverse mechanically and electrically requirements with modularity, weather conditions. pre-assembled by Robur to redundancy and staging An individual module offers a operate as one integrated capability. Ideal for custom nominal heating output of system. Packages with up to residential, commercial or 110,900 BTU/h with hot water five modules are available, industrial applications.
