CONDENSING GENERATORS
Wall-hung gas condensing modules
Condexa Pro

PRODUCT OVERVIEW

Condexa PRO is the new Riello proposal as a modular condensing wall-hung system, capable to ensure extremely high
performance levels and to cover a wide range of applications for indoor installation, with sealed combustion; stand alone or
cascade configurations are possible with heat outputs up to 970 kW.
The range consists of 3 models with thermal modules from 45 up to 97 kW. 70 P and 100 P models are equipped with the innovative
heat exchanger with patented geometries, consisting of two smooth concentric stainless steel pipes, each having a pentagonal
inner section and a circular outer section, designed to maximize the exchange surface and offer maximum corrosion resistance.
The 50 P model is equipped with an helical, single principle exchanger, with a "P" shaped cross section.
The primary circuit pump with modulating regulation allows working with a settable constant DT, reducing set-up plant
regime times and maximizing condensation. The basic electronics include climate control, module cascade management, with
integrated master / slave functions, automatic summer / winter switching and the possibility of managing both a direct zone
and a DHW tank.
The electronics also offers the possibility of remote management via 0-10V input or with the Modbus protocol. Standard
equipment includes: boiler drain tap, safety valves, LPG conversion kit, wall support and the condensate drain syphon. Through
appropriate accessories there is also the possibility of managing the distribution of the secondary circuit, up to 16 mixed zones.
The optimal combustion management and the high modulation ratios from 1 up to 50 for the cascade installations with 10
thermal modules allow high efficiencies and low pollutant emissions (Class 6, UNI EN 15502-1).
– Service continuity is guaranteed by the system modularity: even in the case of a module failure, the overall operation it is
not prejudiced;
– The anti-freeze and anti-seize functions ensure operation in all weather conditions
– Maximum operating pressure: 3 bar
– A wide range of accessories is available to ensure a simple, fast and complete cascade installation.
