BWT Perla – developed for all those who refuse to compromise. Two columns with exchange medium ensure silky-soft BWT Luxury Water around the clock as well as maximum peak water flow.
When the exchange medium in one column is exhausted, the other one automatically steps into action. You thus enjoy silky-soft BWT Luxury water 24 hours a day, 7 days a week without interruption. Thanks to its adaptive parallel operation, BWT Perla also achieves the maximum peak water flow of up to 53 litres a minute. Your silky-soft Luxury Water is thus always available throughout your home even when it's running from multiple taps at the same time or modern comfort showers are being used.
The BWT safety systems of your BWT Perla One also protect your home comprehensively against water damage:
The BWT Perla is a duplex water softener that operates according to the ion exchange process. Calcium and magnesium ions are removed from the water and replaced with sodium ions. The result: no limescale, silky-soft BWT Luxury Water. The two columns are filled with an organic ion exchange medium (resin).
On the front of the BWT Perla you'll find:
When not in use, the device status display (BWT logo) and the touch display are in power save mode and switched off. When you approach your BWT Perla, the displays are activated via a proximity sensor and switched on.
The operating mode of the BWT Perla depends on the given consumption, i.e. the amount of Luxury Water you need over a day. The water flows adaptively to demand in parallel through the two columns which are filled with an organic ion exchange medium. This operating mode enables maximum availability of Luxury Water while simultaneously minimising stagnation in the columns. Furthermore, the only time when water does not flow in parallel through the columns is during the regeneration process.
During the regeneration phases at night – times when less water is typically consumed – one column softens the water while the other is used for regeneration. If capacity usage drops below 50% before the time when it is checked at 2:00 a.m. – i.e. before normal regeneration – proportional regeneration starts immediately.
If the capacity only falls below 50% after the time when it is checked, the unit assumes that the remaining capacity is sufficient to last until the time of the next regular regeneration. Regeneration begins immediately when capacity has been reached or no later than the time of the regular regeneration.
The system is fitted with a device that disinfects the exchange medium with brine during regeneration. While the brine is being drawn, the regeneration process is adapted to the respective pressure ratios, the consumption of salt and regenerating water is reduced to the necessary minimum – a process known as precision salt metering. These processes are based on the exact recording of all measurement data.
Thanks to the optimised brine preparation process, it takes less than half an hour to produce only as much brine as is actually 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.
