Automatic softener REK

REK, The automatic water softener by DVA

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

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;
  • 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, 3/8 "G) for hook-ups to the water mains guarantees adaptability to any system without having to make any changes.

Built-in flood protection and overflow connection systems

REK has included the “Anti-flooding device” which has the task to preventing water from escaping from the brine vat of the softener. It will be advisable to check the cause and the good functioning of the softener if it should become operational. The anti-flooding device is completely integrated into the structure and does not "subtract" space from the brine vat.

Built-in overflow fitting
The new REK water softener has a non-return valve to prevent water from returning to the tank This mechanism strengthens the work of the anti-flooding device.

It should be remembered that the "overflow and anti-flooding system" do not affect the operation of the softener.
