Caldera de Electrodos Trifásica Moderna – 9 kW (R Series)
 
GAZDA R 3-9 is a compact caldera de electrodos trifásica designed para closed calefacción systems y operación segura con residual current protection (RCD).
 
el caldera housing is plastic-coated, providing electrical insulation y allowing safe installation en systems equipped con an RCD.
 
It operates en standard tap water (recommended conductivity: 200–300 µS/cm). en most installations, no water adjustment is required.
 
el caldera converts electrical energy directly into heat through el calefacción medium (water), ensuring fast response y stable potencia output.
