Sizes 160 (13.3 tons), 192 (16 tons), 240 (20 tons) and 300 (25 tons) have been added to the Tranquility Compact Belt Drive (TC) Series. These sizes are only available in a vertical cabinet. Vertical unit configurations can be ordered with front or back return air and top, front, or back supply air discharge. The air discharge is field-convertible using all existing parts including panels and belts. The electrical box can also be field converted to either side of the unit. The small footprint allows the units to be installed in tight spaces. They have an extended-range refrigerant circuit, and can be installed in ground loop, ground water, as well as water loop (boiler-tower) applications. Features include microprocessor controls, galvanized steel cabinet, epoxy powder coat-painted front access panels, galvanized steel with epoxy powder coat-painted drain pan, and TXV refrigerant metering devices.
