OPERA

Condensing hot water generator

The OPERA range consists of six modular condensing generators with high water content, ideal for newly designed systems and particularly suitable also for the upgrade of existing thermal power plants. The technical specifications of OPERA and in particular the high water content, allow it to be inserted in any type of heating system regardless of the engineering choices that the designer wants to pursue. The generators of the OPERA range can be installed individually or up to three modules in cascade (INAIL certified) for a maximum overall power of 1.346 kW. The efficiency of the OPERA range allows the client to access the economic incentives currently in place for upgrading conditioning systems.

The large water content of the boiler and its vertical extension ensure the generators of the OPERA series have very low pressure drops even at high flow rates and allow the generator to work with ΔT between delivery and return practically free, up to a maximum of 60°C close to zero flow rate. All that translates into great engineering flexibility, which frees the designer from the limits imposed by the type of generator. It can also be connected directly to the system without interposing separation elements, even in the case of multi-zone systems, usually characterised by significant variations in flow rates and Δt between delivery and return to the boiler.
