The Hitachi RAS.B312PCAIBA1 (SENP) is a 1.0-ton fixed-speed split air conditioner designed for reliable cooling in bedrooms and small rooms. It uses a rotary compressor and R32 refrigerant, which provides effective cooling while being more environmentally friendly than older refrigerants. The unit features 100 % copper condenser coils that improve heat transfer and durability, along with anti-corrosion protection to withstand humidity and pollutants. Hitachi’s cooling system delivers consistent airflow and comfort with modes like Turbo Cool for faster temperature drop and Sleep mode for quiet, energy-efficient overnight cooling. The AC includes basic conveniences like auto-restart, timer, self-diagnosis, and stabilizer-free operation, making it suitable for areas with voltage fluctuation. Built with a durable build quality typical of the SENP series, it focuses on simple, dependable performance rather than advanced inverter efficiency features.
