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.

Target and advantages

• Increase boiler efficiency (up to 104%)
• Easy to install and adapt
• High reliability thanks to the use of Long Life Aluminum alloy

Parallel-flow condensers have totally replaced the mechanical condensers (Cu/Al) in the automotive industry.The same is happening in all the cooling-related industries (commercial and industrial air conditioning, commercial and industrial refrigeration, etc…). The acceptance of the market for this new kind of condensers is growing every year as their applications are multiplying.

Parallel-flow condensers are completely made in aluminium and brazed in the Valmex plant with a braze welding process in a Nocolok furnace. All the components of the condenser are braze-welded to give solidity and perfect conductivity.

It is possible to produce the parallel-flow condensers with one level (21 mm or 25 mm thickness) or two levels (50 mm thickness). More elements are: frontal dimensions, pace and type of fins, circuits, connections, supports.
