In order to achieve the maximum energy efficiency in a space-saving solution, Riello offers the new condensing system CONDEXA PRO3
EXT, ready to install, composed of:
- stainless-steel boxes containing 115 kW thermal units, flow and return hydraulic manifolds, high efficiency pump for each single
thermal unit
- stainless-steel boxes with hydraulic header/separator.
Each unit contains a patented heat-exchanger made of a stainless-steel pentagonal pipe and a corrugated bi-metallic pipe, ensuring
a high exchange surface, resistance to corrosion and possibility to operate with high ΔT.
The electronic includes thermoregulation, the management of the thermal modules cascade and the possibility to manage a direct
zone, a mixed zone and a DHW tank.
By means of specific accessories it is possible to add up to 16 mixed zones.
The optimized combustion management and the high modulation ratios, up to 1:50 for the version with 10 thermal units, ensure high
efficiency while reducing polluting emissions to a minimum (Class 5 of the UNI EN 297 standard).
- The modularity of the system ensures highest reliability: even in case of a fault or maintenance on one boiler unit, the operation of
the whole system is not affected
- The frost protection and anti-block function allow the boiler to operate in all weather conditions
- Maximum operating pressure: 6 bar
- A wide range of accessories is available to ensure an easy, fast and complete installation.
