The story of Hetzel & Hetzel Enterprises and the “Kythan Safety Firefighting Nozzle” began in 1996 Saudi Arabia when inventor, Lonnie Downs, was conducting testing of some products using the Venturi effect. It was realized that due to the Venturi effect, there was no backpressure on the nozzle which was designed on the theory of the Venturi tube. After years of building and testing prototypes, making application for patent and meeting industry standards, Hetzel & Hetzel Enterprises is proud to introduce to the world this revolutionary firefighting nozzle, which is the Safest to Use , and Most Versatile  Ever Invented.
