Late spring frosts are one of the greatest challenges vine growers are facing. Non-heated vines can suffer considerable inflorescence damages (up to 50%), whilst heated vines will have dramatically improved protection of harvest loss or damage and reduce the losses to approximately 13-20%.
Electric Heating solves the challenge with energy efficient systems using Electric Heating cables to protect vines against frost damage. Vineyard Frost Protection by Danfoss is a sustainable solution for a green and clean future through low energy consumption during the frost period allowing to safe up to 87% of harvest. Vineyards frost protection by Danfoss is an ideal solution for any vineyard dimension.

The heating cables by Danfoss are installed and fixed on metal wire along the grapes. ​
The system is controlled automatically by temperature sensors connected to the controller.​

The Electric heating system product portfolio for the Vineyards Frost protection consists of three major components:​
- a heating element – heating cable with constant wattage or a self-limiting heating cable​
- a controller with a temperature sensor or a controller with both temperature and moisture sensors​
- fixing elements and accessories​

Most of cables are manufactured as ready-made heating elements with a specific length, with connecting power supply cable (cold lead or cold tail) and sealed joints (connection muffs or end terminals).​
Range of the heating cables' linear output for vineyards frost protection is usually between 10 and 20 W/m (Watt per linear meter).​

To choose the best solution it’s necessary to:​

  • Consider vinery’s geographical position and temperature fluctuations to choose the corresponding power necessary per meter​
  • Indicate length of each row of vines​
  • Contact for technical support
