Cutting-edge features make installation easier than many competitive models.


St. Louis — During January of 2017, Nortek Global HVAC introduced a new line of commercial variable refrigerant flow (VRF) multi-zone systems. The complete line consists of V5 mini VRF heat pumps, V5 modular heat pumps and V5 heat recovery systems.


These VRF systems have design features that make installations easier than competitive models. These include:

  •          User-friendly selection software.
  •          Longer piping lengths for more flexibility on each job.
  •          Simpler, easier to install communication wiring.
  •          -22°F (-30°C) heating performance – the best in the industry.
  •          Auto-addressing indoor units, eliminating the need to set dipswitches manually
  •          Simple debugging/commissioning software.


The V5 VRF systems feature DC inverter-driven compressors for precise temperature control. Up to 3,280 feet (1,000 meters) of total piping length and up to 36 indoor connections make them easy to install, network and maintain. Standard gold and blue fin coating provides increased performance and greater corrosion resistance.


The V5 mini VRF systems are designed for light commercial or residential applications. Their compact design and inner profile make them adaptable to tight spaces. Up to 984 feet (300 meters) of total pipe length simplifies installation. Both feature an energy- efficient, ultra-quiet DC inverter compressor and powerful heating capacity in low ambient temperature. These 208/230V condensers are available in 3, 4 or 5 tons and will accommodate up to 7, 8 or 9 zones.


Indoor units are available in wall-mounted, ceiling cassettes, consoles, universal floor/ceiling and ducted type units.

“Commercial VRF systems are growing in popularity due to their efficiency and flexibility,” says Keith Clark, Nortek Global HVAC VRF national sales manager. “We’re proud to offer a high-value VRF product at a reasonable price so our contractor customers can be competitive on jobs.”
