Nortek Air Solutions is a leader and innovator in custom HVAC efficiency.

Our unique designs, innovative solutions, and advanced technology contribute to systems and components that are efficient, environmentally responsible, high performance, and reliable—and can help you save energy.

Energy efficiency is not one thing but a combination of design elements that add up to the savings you seek. Elements like:

  • FANWALL arrays
  • ECMi motors
  • IE5+ Ultimate Efficiency motors
  • Variable frequency drives
  • Fan System Optimization Controls
  • Low pressure fan backdraft damper
  • Energy recovery heat exchangers:  total energy and sensible wheels, total energy and sensible plates, heat pipes, coil runaround loops
  • Variable capacity compressors
  • New refrigerants
  • Low air and water pressure drop heating & cooling coils
  • Evaporative condensing
  • Humidifiers
  • Air and water source heat pumps
  • Filtration

FANWALL TECHNOLOGY®

  • Ultra-high efficiency Permanent Magnet (PM) Motors have proven to be 7% – 15% more efficient compared to NEMA Premium® efficiency induction motors.
  • Variable Frequency Drives (VFD) enable individual on/off and speed control of fans to maintain peak static efficiency and pressure over the air handler operating range.
  • Fans come in 8 sizes from 10 – 27 inches to match performance requirements and optimize operation efficiency.

Economizers

Waterside economizer (WiSE) coils can be placed on both evaporative and air cooled units to pre-cool fluid before it reaches the compressor(s), reducing the amount of mechanical cooling needed to meet load requirements. As a result, energy costs are reduced.

Variable Capacity Compressors

Building loads can vary throughout the day and the ability to save considerable energy costs should not be ignored. There is a falloff in efficiency at part-load conditions of a variable volume digital compressor vs. a variable speed compressor. As most applications tend to have a varying cooling demand, this is one area where variable speed compressors have the edge over fixed-speed compressors. Additionally, local government or utilities may provide energy-saving incentives for using a variable speed compressor to improve the energy efficiency of a building.

Evaporative Condensing

Nortek Air Solutions Mammoth brand pioneered the use of evaporative condensers in commercial HVAC applications more than 40 years ago. Our innovative process uses the cooling effect of evaporation to lower the condensing temperature in a DX system.

Energy Recovery Systems

Energy Recovery Systems use the energy in building air that would normally be exhausted to treat the incoming ventilation air. Our innovative energy recovery systems improve the efficiency, indoor air quality, and moisture control of your air handling solution.
