Heating, ventilation and air conditioning

Domel Heating, ventilation and air conditioning

Buildings consume about 40% of all energy worldwide, and HVAC systems account for more than 40% of individual buildings’ energy usage. That is why low-energy HVAC systems are essential for the future. An important part of this is motor efficiency throughout the whole range of operating speeds.

AZ, ZZ, NZ, and NZA motors are highly efficient permanent magnet synchronous motors (PMSM) manufactured with ferrite magnets. AZ and ZZ motors have compact designs, optimized for low- and medium-speed applications. NZ and NZA motors are suitable for operation across the full speed range. NZA motors are built using standard IEC frames.

Motor type NS 65/771 can be produced with integrated drive.

 

For applications: 

  • air handling units,
  • data centre cooling,
  • ventilation for agriculture,
  • roof fans,
  • box fans,
  • cooling towers,
  • air heaters,
  • heat pumps,
  • heat recovery units,
  • chillers,
  • clean rooms,
  • condensers.

Used in different type of fans:

  • centrifugal,
  • axial,
  • plug/plenum,
  • mixed flow,
  • cross flow.

 

Main Advantages of PM motors 

  • Proven ultra-high efficiency, exceeding requirements equivalent to IE5,
  • Up to 40% lower losses compared to equivalent IE3 asynchronous motors with frequency converters,
  • Exceptional efficiency levels over the whole operating speed range,
  • Speeds up to 6,000 rpm,
  • Very low noise and vibrations,
  • Maintenance free operation,
  • Use of ferrite magnets,
  • Higher power densities allowing smaller frame sizes,
  • Longer life time due to low temperature rise,
  • ROI.
