DANFOSS MTCV

Many Domestic Hot Water systems in residential and commercial buildings are not optimized to perform to their best. Hydronic imbalance causes temperature differences, waste of energy and poor user comfort. Worst case, the systems can even allow growth of the dangerous Legionella bacteria.

Danfoss MTCV optimizes the performance and eliminates the disadvantages in an efficient way. Hot water is available when and where you need it while the pump energy is reduced.

The balancing valve is mounted in the circulation pipe of all hot water risers. It provides a thermostatic balancing function within the temperature range of 35 to 60 °C. It ensures a constant temperature in every circulation pipe, automatic hydronic balance of the system and sufficient high temperatures at all the water taps.

Disinfection options

The basic version (MTCV-A) provides proper system optimization and prevents Legionella to grow. For systems where periodical thermal disinfection* is required the basic valve can – under operation conditions – easily be upgraded with the following modules and accessories:

• an automatic (self-acting) thermal disinfection module (MTCV-B)
• an electronically controlled disinfection module (MTCV-C, in combination with CCR2+)
• a thermometer or electronic temperature registration

* To disinfect the system, modules alone are not enough. The water in the system must first be overheated to a “disinfection temperature” and maintained at this temperature for a certain period of time. Danfoss CCR2+ is recommended to ensure sufficiently high temperatures when using electronic disinfection.
