SBS-HP SERIES consists of a reversible air-cooled heat pump designed to assicurate an high performance also in case of low ambient temperature, down to -20°C. These units are designed for applications that require reliability, continuity of operation, high performance, reduced management costs and carbon dioxide emissions. This series is composed by three basic models that can by hydraulically an electrically compose to satisfy all final user demands. This simplify maintenance/repair operations (performed only in the damaged module) and the already built installation can be increased in capacity in case of modification of the energy demand.
