This was a new product that everyone was talking about this year. It was from Hydra-Flex Inc. the Aqua-Lsb TX 9000F Chemical Delivery System. Wow that is a mouth full! The big unit (first picture) costs around $15,000 and it replaces all your hydrominders with injectors and delivery pumps. You can supposedly save up to 20% including electricity, water, chemical and maintenance! But not really sure what the difference would be if you regulated your water into your hydrominders? Also the other problem they pointed out was the hydrominder tips ware and that is how the unit saves on chemicals.
The little unit (last picture) I was told was for self-serve but I talked to Hydra-Flex last year (when they only sold injectors) and they said injectors were not good for self-serve, only automatics and tunnels so who knows? The guy was also trying to sell a unit to my Dad. 🙂
