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
