WaterFurnace International Inc. has introduced the Versatec Variable Speed Series in 3- to 6-ton capacities. This commercial variable capacity water source and geothermal heat pump line offers efficiency in a compact cabinet, available in both horizontal and vertical configurations for versatility in any application.
Aurora controls offer energy, refrigeration and optional performance monitoring, while the optional Aurora UPC DDC package uses BACnet, N2 or LON protocols to integrate into building automation systems. With a capacity range of 25 to 100 percent, the Versatec variable speed system scales its output to match building needs, maximizing occupant comfort levels and building savings.
The heat pump line features Copeland Gen2 variable speed scroll compressors and inverter drives. Its brushless permanent magnet motor, along with variable volume ratio and high volumetric efficiency valves, provide performance and reliability.
The units also include all-aluminum air coils. An optional AlumiSeal coating offers added protection. Additional features include:
- Optional modulating reheat that modulates via compressor speed to deliver low-humidity neutral air
- Electronic expansion valve with superheat envelope control that provides optimal refrigerant flow in the variable capacity system to ensure efficiency and compressor reliability
- Integrated EC direct drive fan motors with an oversized forward curve blower on select models that provide efficiency and constant CFM, no matter the external static pressure
The line also features cabinets constructed of galvanized steel for corrosion resistance. Units are available with a white powder coat finish or unpainted. All interior surfaces are lined with ½-inch-thick, foil-lined acoustic-type fiber insulation, applied in a manner that prevents the introduction of glass fibers into the airstream.
