The system dissolves salts in powder form from sacks of between 25 and 50 kg or big-bags so that they can be stored in tanks and dispensed to machines in a stable liquid form.

The system has an Atlantis controller for the dissolution process. There is a register for setting up different dissolution programmes according to product type.

Suitable for other salts or auxiliary compounds in powder form (please consult).


  • Elimination of the need for handling sacks of salt anywhere in the plant;
  • Reduction of working liabilities and improved ergonomics for workers;
  • Improved dissolution process, maintaining a stable dissolution and constant concentration at all times;
  • Elimination of salt residues. All the salt is used for the dissolution;
  • Optimisation of worker time on machine and weighing scales thanks to the fact that the machine automatically processes the dissolution and the dyeing machine ‘asks’ to be filled with salt automatically;
  • Better stock control and the option for working with big-bags. 
  • Number of dissolution tanks: 1
  • Capacity of tank(s) in litres: 1000
  • Number of products: 1
  • Preparation capacity:
    • 8.000 Kg salt/ 24-hours (*) with cold water 10.000 Kg salt/ 24 hours (*) with water at 50ºC
    • Salt/water ratio: 275 gr/litre of dissolution (*)

       * These values may vary depending on salt and water quality.
