Water Softening System KVD-613 excl. hose

BWT KVD-613 water softening system ensures constant scale-free water

BWT KVD-613 is a volume-controlled duplex water softening system that delivers soft water to professional environments without the use of electricity. With two separate tanks and intelligent flow control, the system provides a stable supply of scale-free water with minimal salt and water consumption.

Ideal for car washes, commercial kitchens, laundry facilities, and other industrial applications where scale-free water is essential for operational reliability and the longevity of technical installations.

Reliable and maintenance-free softening

The KVD-613 operates entirely without electricity, making installation simple and flexible. The two built-in water meters are activated solely by the flow of water, so once the system has been set to the local water hardness, it runs fully automatically. This eliminates the risk of downtime due to power failures and significantly reduces maintenance requirements. The electricity-free operation also means lower running costs and increased reliability in demanding environments.

Continuous water supply with duplex design

With two separate tanks, the KVD-613 ensures an uninterrupted supply of soft water. Whilst one tank regenerates, the other continues to deliver treated water. This duplex design is particularly valuable in businesses where even brief interruptions to the water supply can cause production stoppages or reduced service quality. Regeneration takes place in counterflow, which both protects the system and significantly reduces salt and water consumption – using only 0.5 kg of salt per regeneration cycle.

Technically refined and economically advantageous

BWT KVD-613 uses only soft water for regeneration, protecting the internal components against limescale deposits and extending the system's service life. The compact construction (weight 18 kg) makes it easy to position the unit even in confined spaces. Please note that a mounting kit with hoses must be ordered separately to ensure correct installation tailored to your specific environment.

With BWT KVD-613 you get:

• An electricity-free, self-regulating water softening system with duplex design
• Significantly reduced salt and water consumption compared to standard systems
• Continuous supply of soft water without interruption during regeneration

Frequently asked questions

How often does the BWT KVD-613 need to be refilled with salt?

Salt consumption depends on water usage and local water hardness, but at only 0.5 kg of salt per regeneration cycle, consumption is very low. Under normal use, the salt container typically needs to be topped up every 2–4 weeks.

Does the system require special maintenance?

No, the KVD-613 requires minimal maintenance. In addition to regular salt replenishment, an annual service inspection is recommended to ensure optimum performance and maximum service life.
