The BWT Perla operates according to your water usage patterns, for example the amount of Luxury Water you use in one day is considered. The water flow is adapted to meet the demand when going through the two exchange medium columns that are filled with ion. This operating mode ensures maximum availability of Luxury Water whilst also minimising the risk of inactivity in the two columns. The only time this does not occur is during the regeneration process.
Duplex system for 24 hours of Luxury Water
BWT’s Perla is a duplex water softener that operates through an ion exchange process. During the ion exchange process calcium and magnesium ions are removed from the water and replaced with sodium ions. This results in zero limescale and silky, soft BWT Luxury Water. The two columns are filled with an organic ion exchange medium (resin).
Thanks to the optimised brine preparation process, it takes less than half an hour to produce only as much brine as is needed for regeneration. The brine collects in a special recess of the regenerating medium tank, from where it is drawn. Once the brine has been drawn, the regenerating medium tank no longer contains any liquid. An ultrasound sensor in the lid measures the fill level of the regenerating medium and displays it as a percentage of availability in the BWT Best Water Home app and on the device display.
BWT Perla water softener in operation – How does it work?
The BWT Perla operates according to your water usage patterns, for example the amount of Luxury Water you use in one day is considered. The water flow is adapted to meet the demand when going through the two exchange medium columns that are filled with ion. This operating mode ensures maximum availability of Luxury Water whilst also minimising the risk of inactivity in the two columns. The only time this does not occur is during the regeneration process.
The regeneration process takes place at night (when less water is used) where only one column softens the water whilst the other is used for regeneration. If capacity usage drops below 50% before the time it is usually checked (before normal regeneration) then proportional regeneration starts immediately.
Feeling Three times the safety
BWT’s Perla safety system provides comprehensive protection for your home against water damage. BWT Perla protects your home from water damage with 3 safety systems:
• AQA Guard floor sensor(s): Up to 10 sensors monitor moisture on the floor (direct protection against, for example, a ruptured washing machine hose).
• AQA Stop: Indispensable leak protection, in case of a major leak, is included free of charge. If the AQA Guard sensor detects moisture, AQA Stop cuts off the water supply in the house.
• AQA Watch: An alarm function that alerts you when prolonged low flow rates are exceeded.
