CONDEXAPRO 500 SERIES CondexaPRO products are suitable for both new buildings and as a replacement on existing systems; for instance old non-efficient floor-standing boilers, and offer the highest efficiency at any time combined with maximum piece of mind. The 500 Series 50kW heat exchangers offer the CondexaPRO range versatile cascading options up to 3MW. The CondexaPRO range consists of three output variations (50kW, 70kW & 100kW) either featuring one heat exchanger (50kW) or two heat exchangers (70kW & 100kW). 1. Pre-mix combustion group, consisting of a modulating gas valve integrated with...

The technology: heat exchanger The CondexaPRO condensing heat exchanger has a high exchange surface and an excellent corrosion resistance. It has a cylindrical shape and it is made of the following components: ■■ Micro-flame burner Stainless steel covering AISI 316L Continuous bi-metallic corrugated helical tube (copper alloy on the water side and stainless steel on the flue side), which is coiled up inside the cover Refractory brick which keeps the heat inside the combustion chamber and forces the flue gases over the heat exchanger, optimising the thermal heat exchange performance Plastic header...

Wall hung and cascade solutions Fully modulating condensing boilers. 4 models (50M, 70M, 100M, 100S) offer versatile cascading solutions to meet commercial building demands. Riello Combustion Sophisticated multi-zone heating control and monitoring which may negate the need for a BMS in some cases 4 Star class A efficiency† Powerful high head fan Each combustion unit can be individually serviced or maintained without loss of other units Large heat exchanger surface area Copper & stainless steel heat exchanger 3 temperature circuits from boiler Up to 8 additional zones via zoning kits (available...

*Measurements obtained using the clapet with which the boiler was homologated. **Measurements taken at 1m from the appliance, at a height of 1.5m with background noise of 36.5 dBA.
