The risk of Legionella contamination in drinking water installations is particularly affected by the water temperatures. To prevent the growth of Legionella, a temperature of 60°C must be continuously maintained at the outlet of the hot water heater. The temperature must not fall below 55°C anywhere in the hot water pipework.

Circulation systems are supposed to fulfil this task, but often fail due to the complex hydraulic conditions. Changing operating conditions repeatedly lead to hygienically unsafe temperature drops in parts of the system.

KEMPER automatic regulating valves detect even the smallest temperature changes and react independently by adjusting the pressure loss, thus ensuring dynamic hydraulic balancing throughout the entire system.
