Designer Riser Master and Slave (DR-M/DR-S)


The Designer Riser Master (DR-M) and Slave (DR-S) Vertical Stack are low-static (up to .25 ESP) fan coils with a draw-through design.   The Master (DR-M) and Slave (DR-S) combination are two separate fan coils designed to be piped to a common set of risers.   The Master (DR-M) units are piped in series, one above the other.   Each Vertical Stack fan coil has its own valves and controls.   The DR-M and DR-S cabinets are galvanized steel, 97 inches in height and insulated with ½-inch thick, over three pound density, neoprene-coated fiberglass.   The DR-M and DR-S units have full easy access through the 36 inch return-air grilles to their separate the ½-inch OD copper tube coil, easy slide-out blower/motor assembly with quick-connect plug and a galvanized steel, powder-coat epoxy drain pan covered with ⅛-inch thick insulation.  The uniquely engineered sound shield and tuning vane in the supply-air plenum provides even distribution of airflow across the grille resulting in quieter operation.   The DR-M/DR-S combination is designed for concealed applications.   Risers are ordered separately due to size changes throughout the building.
