One product, a thousand solutions Condexa Pro is always the right solution Condexa Pro is the principle element in a system that enables almost limitless configurations; ranging from simple ‘standalone’ solutions to modular cascade systems that can accommodate specific requirements with a range of accessories. The range incorporates 8 models (35 P, 50 P, 57 P, 70 P, 90, 100, 115, 135) with the 4 lower output models being equipped with an ‘on-board’ pump as standar

Weather no problem It’s inevitable that in certain circumstances there is no other option but to consider installing the appliance in an external location. With this eventuality in mind, an optional kit is available that raises the appliance IP rating from IPX4D to IPX5D for use in partially protected outdoor spaces. Heat always available The Condexa Pro can also be configured in a modular or cascade arrangement; the integrated logic-control enables a ‘managing’ and ‘dependant’ operation, allowing for the interchangeability of modules and to be isolated for routine servicing without disrupting...

CONDEXA PRO For the past decade, Condexa Pro has been a distinctive core element in the Riello commercial portfolio and synonymous with delivering high thermal efficiency and reliability. Nonetheless, our engineers set their sights on developing a completely new platform and structure that builds on the best attributes of an established product; to ensure the new Condexa Pro typifies the high standards and requirements of today’s market. Each component has been revised or redesigned in order to gain improvements; in particular the main heat exchanger has benefitted from an 18% reduction in surface...

The beating heart The Condexa Pro heat engine lies at the heart of the system and has been designed in absolute unison with the premix burner. The resultant effect is a synergy of combustion and heat transfer - transforming the chemical energy within the fuel into thermal energy that is effortlessly transmitted to water. The heat exchanger is manufactured from high grade stainless steel in order to eliminate the possibility of any change to the structure or inherent reliability over time. The profile, the water pathway and flue pathway have all been optimised to limit losses and ensure the best...

Standalone and cascade solutions Fully modulating condensing boilers. 8 models (35 P, 50 P, 57 P, 70 P, 90, 100, 115 & 135) offer versatile standalone and cascading solutions to meet commercial building demands. New condensing heat exchanger in stainless steel Complete pre-mix combustion and low NOx emissions: Class 6 (EN 15502) Possibility to cascade up to 1120kW (using the embedded ‘Managing/Dependant’ control logic) Thanks to our embedded ‘Managing/Dependant’ control logic, any boiler can be configured either as the ‘Managing’ or as a ‘Dependant’ boiler within the cascade (same product code)...
