Modine model GLW units are specifically designed to heat greenhouses with low-temperature water. They can be successfully used in applications where waste or reject heat from steam-electric power plants, refineries, pumping stations, distilleries, and other industrial or processing plants can be utilized for heating. With the ever-increasing cost of fossil fuel, utilizing reject heat as a heat source for greenhouses or other spaces is a sensible solution. Standard features include:
• Hot water coil with copper tubes, aluminum fins, and 1-1/2″ MPT copper connections for high water flow capability.
• Maximum operating pressure is 300 PSI, maximum operating water temperature is 180°F.
• Frame, enclosure panels, and 24″ polytube transitions are galvanized steel for corrosion resistance in humid environments.
• High airflow, 3850CFM for GLW330S and 7700CFM for GLW660S, based on 150 feet of polytube duct.
