Multifunctional Thermostatic Circulation Valve for establishing safe and energy saving domestic hot water systems

The valves are installed in the circulation pipes from individual system risers and can be set to a temperature between 35 and 60 degrees Celsius. This will bring hydronic balance, short waiting times, water & energy savings and reduce the risk of legionella in tap and drinking water. The valve is made from lead-free brass and is produced in accordance with regulations of many international and national drinking water directives.

Disinfection modules

The MTCV can be equipped with an electronic (MTCV-C) disinfection module. When used the system temperature can temporarily be increased to circulate hot water with a temperature high enough to kill the legionella bacteria. 

Electronic disinfection

CCR2+ is a simple but advanced electronic controller designed to optimize the electronic disinfection of DHW systems. The controller periodically flushes the system, riser per riser, with an increased water temperature to kill any bacteria's in the system. 
It can control up to 20 risers or be expanded with a slave unit for another 16 extra risers. All the temperatures are stored for data logging and analysis.  
The CCR2+ can be connected to a WiFi or cabled network and by that be accessed by a PC or mobile device. For further optimization it is also possible to connect it with a Building Management System (BMS), saving engineering efforts and BMS components that can possibly do the same job. 

Balancing of domestic hot water systems

This animation describes the issues and challenges in domestic hot water systems in non-residential buildings, such as unwanted heat losses, energy inefficiency and risk of legionella.

Features and benefits

Improve comfort

Residents will benefit from fast and equal waiting times when tapping for hot water

Save energy

The system will have a lot less heat losses and run more efficient. The costs for residents will be lower and allocated much more accurate.

Reduce water waste

With hot water at the right temperature available at all times, less water is wasted by waiting or mixing it with cold water to achieve the right consumption temperature.

Lower costs

The system runs more efficient and prevents lime and corrosion, potentially damaging the pipes

Reduce the risk of legionella growth

With the water temperatures being controlled on a level legionella cannot grow the risk for contamination reduces. Of course system construction factors such as long pipes without circulation also need to be prevented.

Short payback time

Typically the investment for installing thermal balancing valves are not that high and can be paid back in a short (1-2 years) period of time.

Lead-free brass

The valves are made from lead-free brass and are in accordance with the regulations of many Drinking Water Directives. The lead-free brass is a step towards improving the quality of the drinking water and meets the requirements of sustainability.

Meets individual needs

MTCV basic version (A) – provides a thermostatic balancing function within the temperature range of 35 to 60°C. For systems, where periodical thermal disinfection is required, the basic valve can easily be upgraded with a disinfection module – version C – for electronic, automatic, control of a periodic thermal disinfection process.

Automated disinfection 
Establish the most safe DHW conditions with the highest possible efficiency and reduce time spent on monitoring and data logging.
