Frost protection

Frost Protection, by the method of consuming the cold air in your orchard, warming it and then redistributing it.

Splash Direct Heat Dragon

Affordable Frost Protection

The very versatile Heat Dragon can be placed in a frost prone area of your vineyard/orchard and left as a stationery unit. It will combat frost by consuming 50,000m/3 per hour of cold air and heating it up to 80 degrees Celsius. Thus giving you a double benefit effect, removing cold air plus adding the warming effect of heat. The Heat Dragon can also be used as a mobile unit in flat orchards, with the twin outlet ducts it will cover an area of 2 hectares up to a maximum of 4.5 hectares. The twin tail ducts direct the airflow out sideways, if the unit is to be driven around the vineyard/orchard for frost protection.

The Heat Dragon can also be used in conjunction with existing frost fans, windmills and other air displacement methods.
