ALUMINUM HEAT RECUPERATORS FOR SEMI CONDENSING GAS BOILERS
ALEX RS
Modularity and resistance
Recuperator Alex-RS can be applied to the entire range of domestic boilers up to an output of 32 kW. Furthermore, thanks to the welded Aluminum body, thermal conductivity and corrosion resistance are optimized for the appliance.
The product is completely welded using specific Aluminum alloys (Long Life Alloy) developed with main producers to increase corrosion resistance.
New recuperator in the boiler
The combustion products go from the hood into the recuperator at a temperature range of 130-160 °C, while the water arrives from the circuit at a temperature range of 30-60 °C (depending on the boiler setting). The contact between the two mediums allows a further heat exchange and a gain of efficiency.
The combustion products exit from the boiler at a temperature range of 50-70 °C, while the preheated water of the circuit goes into the primary heat exchanger.
The possible condensation inside the recuperator is conveyed into a specific drainpipe.
The exchange body of the recuperator is completely realized in Aluminum and consequently it is recommended to use inhibiters against corrosion, the antifreeze and the cleaning solutions.
