Automatic softener NOA

NOA, the automatic DVA water softener

The NOA automatic water softener is a new model in the AL series, designed to offer more advantages, including extreme simplicity and speed of programming.
NOA has been studied ad hoc on the basis of the experience of operators in the catering and bar sector, following the indications collected from the sector technicians who use every day coffee machines, cup washers, dishwashers, ice makers, steam ovens, etc.
The compact dimensions and the new design of the cabinets have been designed to take up even less space and make NOA softeners suitable for installation in even very small environments.

NOA Automatic Water Softener - Scheda tecnica

Practical for the final user

Some adjustments make this softener extremely practical:

  • the innovative system of release of the cylinder from the brine body facilitates the cleaning and maintenance of the softener;
  • the convenient opening of the lid, which remains attached to the salt container when opening, makes it easier to insert the salt into the brine vat and protects the upper part of the softener from shocks;
  • The "salt check" function will remind us to check for the presence of salt in brine
  • an anti-flooding device prevents water from escaping from the brine vat of the softener and is fully integrated into the structure and does not "subtract" space from the brine vat;
  • the softener is equipped with a non-return valve to prevent water from returning to the brine tank;
  • the overflow fitting and flood protection system are no longer accessories, but become an integral part of the softener;
  • the possibility of choosing the connection (3/4 "G or 3/8 "G) for hook-ups to the water mains guarantees adaptability to any system without having to make any changes.
