Outdoor coil and/or indoor coil (and hot water coil) with copper tubes and copper fins. Outdoor coil and/or indoor coil (and hot water coil) with copper tubes and fins of an aluminium alloy (INERA®), of high performance and great resistance to the corrosion. Outdoor coil and/or indoor coil (and hot water coil) with copper tubes and aluminium fins with polyurethane coating. Outdoor coil and/or indoor coil (and hot water coil) with copper tubes and aluminium fins with Blygold® coating.
Auxiliary hot water coil, with three-way valve and proportional control, for assembly inside the unit. There are two configuration types available: • Standard (B0S), this option always incorporates an antifreeze thermostat as a safety device. Consult for percentages of glycol water above 20%. • Great Cold (B0C), with anti-freeze technology based on the water temperature. This protection is made up of a circulation pump, two sensors inserted in the input and the output of the coil, as well as an electrical heating for the piping layout.. Important: this option is mandatory for an outdoor temperature lower than -20ºC WB. Gas boiler + Auxiliary hot water coil. The circuit of the auxilary water coil (installed inside the unit) is connected to the gas boiler.
Natural or propane gas burner with modulating actuator, in accordance with the Gas Directive 2009/142/EC, installed into a pre-assemby roofcurb (optionally supplied with the unit). Condensation boiler with premixing and modulation technology that allows outputs close to 109% with regard to the lower heating value (LHV).
