AC-00 Nodule
Five year warranty

 

     In September 1997, CRISTOPIA has launched a new product : the AC-00 nodule. This new nodule is an optimisation of the world-wide successful C-00 nodule. Thanks to the use of a high-tech material the AC-00 nodule has :
  • very high thermal characteristics (as good as the C-00 nodules),
  • a very long life time (equal to a building life time),
  • a very competitive price (lower than the C-00 nodules).

      Its main technical characteristics are listed below. One must notice that the commissioning and the expansion of the AC-00 nodules are slightly different from the C-00 nodules. Indeed, one week after commissioning, some brine must be added to the STL to compensate the volume variation due to the service pressure.
