Descaling System - Compact - 30l/min - 265mm - 310600g

BWT KVD-621 descaling system ensures lime-free water around the clock

The BWT KVD-621 is a compact and intelligent water softening system that removes lime from water without the need for electricity. With a capacity of 30 liters per minute and a duplex design, this system ensures a continuous supply of soft water, even during regeneration.

Ideal for professional environments such as textile washing, dishwashers, steam ovens, and car washes, where lime-free water is crucial for operational reliability and longevity.

Intelligent softening without energy consumption

The KVD-621 operates entirely without electricity, thanks to two built-in water meters that automatically monitor consumption and initiate the regeneration process when necessary. You only need to set the system once according to the local water hardness—after that, it works fully automatically. This makes installation straightforward and operational costs minimal, as there is no need for electrical wiring or complex programming.

Continuous operation with duplex technology

The advanced duplex design means that the system never compromises the water supply. While one tank is being regenerated, the other automatically takes over, ensuring uninterrupted access to soft water. This is especially valuable in professional settings where production downtime can be costly. The regeneration process uses only 1 kg of salt per cycle and takes place with soft water in counterflow, which reduces operating costs and extends the lifespan of the filter medium.

Documented benefits of lime-free water

By installing the BWT KVD-621, you achieve significantly longer lifespans for your machines and installations. Lime deposits are effectively prevented, leading to fewer repairs, less maintenance, and lower energy consumption. Machines that use water operate more reliably, and the quality of end products improves—whether it’s cleaner textiles, sparkling tableware, or better steam quality. At the same time, the consumption of cleaning agents is reduced as soft water cleans more effectively.

With the BWT KVD-621 descaling system, you get:

• Automatic softening without energy consumption and minimal maintenance
• Uninterrupted supply of soft water with a capacity of 30 liters per minute
• Cost-effective operation with low salt consumption of only 1 kg per regeneration cycle

Frequently asked questions

How often do I need to refill salt in the system?

The salt consumption is only 1 kg per regeneration cycle. The refilling interval depends on water usage and the hardness of the water in your area, but the system is designed to be economical in operation.

Does the system require special installation or maintenance?

The system requires professional installation for the water supply, but since it operates without electricity, the installation is relatively straightforward. Maintenance is minimal and primarily consists of refilling salt and periodically checking the settings.
