The F501 is already the third generation of the Frostbuster. It’s are most powerful machine. The most important improvements, compared to the previous generation (F401), are:

  • New pulse burner with burner controller and ionization sensor, which makes it the safest burner used in agriculture.
  • The F501 can hold 8 or 10 gas bottles, so it has a bigger autonomy, up to 10 hours.
  • Now also available with 340 kg drum.
  • The burner starts automatically, depending on the RPM of the fan: if a certain speed level (RPM of fan) is exceeded, the burner will start automatically. When the speed drops back below this level, the burner will be switched off.
  • Gear box with overrunning clutch.
  • The temperature can be adjusted from the control box in the tractor’s cabine (option)

The F501 can also be equipped with a drum that can contain 340 kg of gas.


  • The replacement of an empty drum by a full drum takes only 5 mintes.
  • No loss of unused gas.
  • The price per kg gas is much cheaper than gas in bottles.
  • It’s much easier and faster to replace one drum then replacing 8 or 10 gas bottles.
