EOLE frost protection towers and hail protection systems (shock waves)
The SPAG Group specialises in climate protection for orchards and vineyards, operating since 1972 (founded by Fred Ollivier in Manosque, southern France), with over 50 years of experience and a presence in 30 countries. EOLE frost protection towers use temperature inversion: they bring warmer air from the upper layer down to the plants at ground level, protecting blossoms and fruit set down to -6°C (with heater) or -4°C (without) over an area of up to 7.2 ha per tower. The second line is hail protection systems based on shock waves (a hail cannon, not a net): a wave emitted every 7 seconds breaks up forming hailstones, protecting at least 80 ha. The main production plant is located in Godelleta (Valencia, Spain).
- 01Protection down to -6°C with heater (down to -4°C without) — coverage of up to 7.2 ha from one EOLE tower
- 02Temperature inversion principle — brings warmer air from above down to the plants at ground level
- 03Static and Tilting versions; diesel drive (163 hp/120 kW), gas, electric (100 kW) or PTO
- 04Automation: 2 temperature sensors in the zone + 1 sensor at 100 m from the tower, anemometer, solar panel
- 05Over 50 years of experience in crop protection (since 1972), presence in 30 countries
Godelleta (Valencia), Spain
The SPAG Group (Grupo SPAG, “Sociedad Protección Anti Granizo”) was founded in 1972 in Manosque, southern France, where orchardist Fred Ollivier, after six consecutive years of crop losses caused by hail, developed and patented a protection system based on shock waves. Today the company is run by his son David Ollivier (CEO, SPAG Group). The main production plant is located in Godelleta near Valencia (Spain), and the machines work in 30 countries. The flagship product is the EOLE frost protection tower, which operates on the principle of temperature inversion, in stationary (Static) and tilting (Tilting) versions, with diesel, gas, electric or PTO drive. The second line is hail protection systems based on shock waves: a hail cannon, not a net. RUTHENIA ALBA handles distribution in Poland.
