  • Reduced Crop Losses using warm air for higher protection
  • Quiet operation, between 30 and 54 dB at 200m, and no resource consents required
  • Portable as the wheels and draw bar provides easy shifting
  • It is available for a range of climate enhancement options
  • Does not rely on the presence of an inversion layer that helicopters and wind machines rely on
  • Puts you back in control, providing increased peace of mind and designed by people who have been there
