tubra®-FRISTA XL/KXL

The versatile cascadable fresh water station for large systems

An electronically controlled fresh water station with Tuxhorn fresh water controller, 6-fold cascadable for large tapping capacities up to 498 l/min.

One station for single and cascade application – the function is assigned during commissioning. A CW free-flow valve is available as an accessory for the single station, and a cascade ball valve set is available for cascade applications.
Scheme FRISTA L/KL

tubra®-FRISTA KXL – the cascade solution for large plants:

tubra®-nemux KS, tubra®-nemux KM, tubra®-FRISTA KL, FRISTA KXL rely on cross-station logic. Best operational reliability with highest temperature accuracy.

All stations are bidirectionally connected. This means that the entire system can be set via one control panel, with all important information available centrally. The controller is capable of issuing a collective fault signal and can thus be used for building management systems. Cascades offer the possibility to add outputs of several stations. Stations are combined to achieve the required performance.

The advantage over large fresh water stations is that the hot water volume flows can be regulated more precisely by several individual stations. The next station is only switched on when a switch-on threshold is reached.
