WaterFurnace International introduced the Versatec Variable Speed Series in 3- to 6-ton capacities. This commercial variable capacity water source and geothermal heat pump line is available in both horizontal and vertical configurations. Aurora advanced controls offer true energy, refrigeration, and optional performance monitoring while the optional Aurora UPC DDC package uses BACnet, N2, or LON protocols to integrate into a BAS. With a capacity range of 25% to 100%, the Versatec variable speed system scales its output to match building needs, maximizing occupant comfort levels and building savings, according to the company.

The new heat pump line also features the Copeland Gen2 variable speed scroll compressors and inverter drives. The units also include all-aluminum air coils that helps ensure durability and efficiency. An optional AlumiSeal™ coating offers added protection. Additional features include optional modulating reheat that modulates via compressor speed to deliver true low-humidity neutral air and electronic expansion valve with superheat envelope control that provides optimal refrigerant flow in the variable capacity system to ensure high efficiency and compressor reliability.
