The CCR2 system is used in conjunction
with MTCV valves to provide fully
automatic, optimised disinfection
and/or temperature logging for large
hot water systems. By optimising this
process electronically, energy savings
can be made by reducing the overall
disinfection time, and disinfecting
systems riser by riser.
Fully adjustable temperature logging is
available using standard Secure Digital
memory cards (SD). A 512mb SD card,
when fitted to the CCR2 (set to log temps
every 1 minute) will store over 2,000,000
records, or just over 1.5 years of data.
Recording intervals are programmable
and data can be read on any PC as data
files are saved in a common *.txt format
for easy integration into Excel or other
spreadsheet software.
One CCR2 can control 16 risers, this can
be expanded over a larger system by
connecting other units up in serial or
parallel.
Additional functions of the CCR2:
• Indicationofalarmstate
• Pumpprotectionfunction
• Visual indication of the progress of
