Riello CONDEXA PRO is a condensing pre-mixed, fan-induced modulating wall-hung boiler, designed both for stand-alone and cascade applications up to 2.4 ML Btu/hr (702 kW). It is suitable for a wide variety of installations, from office buildings and sports facilities to schools and hotels. Each model have a new heat exchanger, composed of two smooth concentric stainless steel pipes (ASME approved), having respectively an internal pentagonal section and a circular outside section, designed to maximise the heat exchange surface and provide maximum resistance to corrosion.

The primary circuit pump with modulating adjustment allows you top operate with a settable consent DT, thereby reducing the system's steady state times and maximising the condensation. The standard electronics includes climatic regulation, management of the cascade of the modules, with integrated master/slave functions, the automatic switching between summer/winter and the possibility of managing a direct zone and a DHW storage cylinder.
