Installation and operating cost profiles compare very favorably with other VAV system options. Installation costs are low since a single duct system is used and the downstream air distribution system serves both the heating and cooling functions.
Operating costs are low since warm plenum air is used for heating, recapturing the heat of lights.
Expensive reheating of cold primary air is eliminated. Electric or hot water heating coils. Pneumatic, electronic and digital controls available. Single-point power connection reduces installed cost. Full factory-run test on each unit.
