Against Frost Candles

TOBO develops and manufactures anti-frost candles for protection of orchards and vineyards against frosting. While burning the candles increase the temperature of the air by heating and a protective blanket of smoke that prevents heat loss. Our candles raise the air temperature up to 7 degrees depending on the quantity of used candles and weather conditions.
