OPERA

CONDENSING THERMAL GENERATOR FOR LARGE VOLUME OF WATER

STRENGTHS:

- High power condensing thermal module with large water content, designed for single or cascade installations, in combination with a complete range of water, gas and flue gas accessories, up to 1350 kW

- Hydraulic, gas and flue gas accessories for cascade installation with 2 and 3 modules

- Flue gas tube heat exchanger, made with AISI 316 Ti stainless steel, with vertical configuration, helical cross-section, set up perpendicularly to the flue gas chamber

- Full pre-mixing combustion unit with metal fibre front combustion burner with very low emissions (CLASS 6 according to EN 15502-1). The modules can run on natural gas and LPG

- The combustion chamber has an extremely contained overall vertical dimension so that the exchange of water/flue gases can take place over the entire extension of the exchanger

- Generator protection systems: Double sensor (delivery and return) system for operation at ∆T constant / Flue gas safety sensor / Water pressure switch with minimum threshold at 0.8 bar

- Air / Flue gas circuit with intake in the installation site and check valve integrated on the intake unit to size the pressurised flue gas manifold

- Control panel protected by a door built into the outer casing with key lock

- Four heavy-duty floating wheels fitted per standard to facilitate unloading and mobility inside the thermal power plant. Adjustable feet for positioning

Technical Data

ADVANTAGES OF OPERA:

- It reaches one of the highest seasonal space heating efficiencies in its category: ηs 94%

- : combined with the modulating remote control and the outdoor probe (optional) it reaches the top efficiency class A+ (scale from G to A+++)

- The large volume of water of the generator allows the boiler to be connected to the system without the need for separating devices and allows for a very high design ∆t

- Management of the modules in cascade set-up with self-configuring MASTER / SLAVE system

- Setting of switching on and off of generators (which can be switched on and off in sequence or work simultaneously in parallel) through the control panel of the MASTER generator

- Electronics on board the machine to manage a system with two direct zones and one DHW storage or systems with differentiated temperatures (direct and mixed) in combination with the thermoregulator THETA+

- RANGE RATED certified generator to adjust the generated power to the system’s needs by increasing the efficiency of the system and preserving the mechanics of the machine

- The modules can be controlled and conducted remotely: Regulation of power or temperature with 0 - 10V signal / Signalling of block alarm for safety and restoration of operation / OPENTHERM (OT) and MODBUS parameterisable communication protocols

- Electronic control of microprocessor combustion allows 1/5 modulation on the single generator and of the 1/20 for the maximum configuration (3 x 450 modules in cascade set-up)
