Basics of spraying technique I Ideal sprayer / accessory for the ideal application
What can I optimise with the ideal sprayer? Goal: The right sprayer for the right application Improved effect/efficiency Time saving Saving of chemicals and spray liquid Cost reduction Improved comfort Increased safety Economic use of resources and protection of enviroment
What do I achieve with the right sprayer? Customer appreciation / acceptance Professional image creation Securing orders /repeat orders Winning new customers Open new earning segments Creating synergies with other products (e.g. chemicals)
Criterias for the right choice of a sprayer Goal: Economic and enviromental sound solutions Which spray media? Water solution (pH 7) Acid (pH 1) Alkaline (pH 14) Solvent…. Which unit? Volume (0.5l till 100l) Application = Chemical = Material of sprayer Accessory
