tubra®-FRISTA XL/KXL

The versatile cascadable fresh water station for large systems

Electronically controlled fresh water station with tuxhorn fresh water regulator, 6-way cascadable for large tap capacities up to 498 l/min.

One station for single and cascade application – the function is assigned during commissioning. A KW free-flow valve is available as an accessory for the individual station, and a cascade ball valve set is available for cascade applications.

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

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 able to issue a collective fault signal and can therefore 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.

Product portfolio Hot water

Fresh water stations from tuxhorn are used exclusively for heating drinking water by means of a buffer tank and an internal plate heat exchanger using the flow-through principle. Only drinking water as defined by the Drinking Water Ordinance may be heated.
