Purity for your heating system

The Grünbeck thermaliQ clean heating system cleaning agent

thermaliQ clean is used in heating systems with a high degree of corrosion and silting. thermaliQ clean dissolves and mobilises deposits and corrosion products. As an alternative to the subsequent draining of the system, it is possible to clean the entire system by means of filtration without having to replace the circulation water. Thanks to the filtration, the agent is removed from the system.

Efficient cleaning of your heating system

thermaliQ clean

thermaliQ clean is a cleaning agent for heating systems and has highly dispersing properties. What to do in case of signs of corrosion and silted pipes? Corrosion and troublesome deposits may especially occur in older heating systems. However, even in this case Grünbeck can provide a solution: Use the new cleaning agent thermaliQ clean before you experience major and expensive damage at your heating system.

thermaliQ clean mobilises dirt particles and deposits and dissolves silting reliably. Depending on the degree of impurities, Grünbeck’s experts recommend a cleaning period of 3 - 6 weeks. Afterwards, the system can be drained and flushed. It is also possible to clean the entire system with the filtration of circulation water (GENO®-VARIO mini). thermaliQ clean is biodegradable and can therefore be discharged into the drain.
