NRB is a dual-circuit chiller charged with R410a gas. It has axial fans to ensure the quietest possible machine operation, scroll compressors with a high yield and low electricity absorption, a plate heat exchanger and “V block” micro-channel coils. The unit with two refrigerant circuits is designed to provide the maximum yield when fully charged, but also guaranteeing excellent efficiency even with partial charging and ensuring continuity if one of the two circuits stops operating. The machine cools water to supply the distribution system that is usually connected to fan coil type terminals. In addition, NRB can also produce domestic hot water if it is fitted with a desuperheater or total recovery system, so it’s ideal for residential, commercial and industrial contexts. There are 4 versions – standard, low noise, high efficiency and extra high efficiency.
