The Sentinel R700 Sanitiser & Biocide is a highly effective solution specifically designed to protect ground or air source heat pump systems. These systems are susceptible to contamination from bacteria and fungi, which can significantly impact their performance and overall health. The Sentinel R700 is formulated to address these issues, ensuring the longevity and optimal functioning of your heat pump system.

Contamination within the system can lead to various problems, including degradation of thermal fluids, blockages, unpleasant odors, and corrosion of system components.

Its non-corrosive formulation ensures that it won't harm system components while effectively neutralizing contaminants. With its long-lasting protection, you can have peace of mind knowing that your heat pump system is safeguarded against bacterial and fungal growth.
