Vertical Discharge Design for High-Bay Applications
The V139S01 uses a downward-discharge configuration to deliver heated air from overhead mounting positions directly into the occupied zone below. A propeller fan draws ambient air laterally across the finned copper coil and pushes it vertically through the bottom outlet.
Modine rates the unit for mounting up to 18 feet at standard steam conditions. The 27-foot throw specification helps you determine spacing between multiple units.
You can adjust the air pattern with optional deflector accessories like cone-jets or louvers, though the unit ships with a standard bottom fan guard for safety. The guard protects the fan blades while allowing full airflow.
Hydronic Connection and Control Options
The V139 connects to your existing steam or hot water loop through a 1 1/2 inch supply and 1 inch return fitting. The copper tube coil handles steam at 2 psig or hot water at equivalent temperatures, producing 139,000 BTU/hr output under standard rating conditions. At 2 psig steam with 60°F entering air, the unit generates a 52°F temperature rise and discharges air at 112°F.
Modine V-Series Vertical Steam and Hot Water Unit Heaters
The V139S01 delivers 139,000 BTU/hr with 2,660 CFM airflow for mid-sized high-bay spaces. The V193S01 provides 193,000 BTU/hr capacity for larger warehouses and manufacturing facilities requiring greater heat output.
