• Inventor - Cherry grower Reinhard Vöhringer

• Looking for a stable cover for his cherry orchard in windy area close to alps

• Existing solutions were not suitable (not wind resistant, too expensive, too time consuming to set up and remove)

• Developed a solution based on proven hailnet technology

• Started the business-VOEN system in 2002

• Today the Vöhringer family have established the VOEN business and has installations worldwide.

• OaKSun was granted the Australian and New Zealand agency for Voen in Feb 2011
