The Hitachi Water Source VRF represents over 70 years of innovation in water-cooled air conditioning technology. For the Bangladeshi market, where high-rise buildings and industrial complexes face intense summer heat, water-source systems provide a massive advantage: they are installed indoors and use a water loop for heat rejection. This means they are completely unaffected by the 40°C+ ambient outdoor temperatures that often degrade the performance of standard air-cooled systems.
Simultaneous Cooling and Heating with Heat Recovery The Heat Recovery type is a game-changer for diverse spaces like meeting rooms, classrooms, and halls. It allows different zones in the same building to operate in cooling or heating modes simultaneously. By exchanging heat energy between the refrigerant circuit and the water loop, these systems are even more efficient than air-source heat recovery units. For example, excess heat removed from a server room can be repurposed to provide hot water or warmth for other areas, drastically reducing total building energy consumption.
Whisper-Quiet Indoor Performance Since the outdoor unit is replaced by an indoor water-source module, operating noise is reduced by up to 6dB, resulting in a quiet output of just 49dB. This makes it the premier choice for noise-sensitive environments like luxury hotel suites, corporate boardrooms, and private healthcare clinics in Dhaka. Furthermore, because it is installed indoors, the system never needs to stop for a "defrosting" cycle, ensuring 100% continuous comfort.
Enhanced Reliability & PCB Protection Industrial environments in Bangladesh often struggle with humidity and electronic failures. Hitachi has solved this by integrating a mini refrigerant circuit specifically to cool the electrical PCB. This prevents the build-up of condensate on sensitive electronics, significantly improving the system's reliability and lifespan in humid conditions.
Advanced Health and Air Quality (IAQ) Occupant well-being is prioritized through Hitachi’s advanced filtration options. The system supports the ViroSense Z filter for 4-way cassettes, providing 99.9% inhibition against SARS-COV-2. This ensures that while you are saving on energy, you are also providing the cleanest possible air for your clients and employees.
Unified Design for Easy Installation Hitachi utilizes a unified design and consistent dimensions across its range. This makes it incredibly easy for engineers and architects to mix Heat Recovery and Heat Pump units on a shared water loop. This flexibility allows for a balanced installation cost while meeting the specific temperature control requirements of different zones within a single project.
A Sustainable Investment with World-Class Pedigree With modules reaching up to 18 Tons (85HP) and the ability to combine three modules into one massive system, Hitachi provides the scalability needed for Bangladesh’s largest infrastructure projects. It is a "High-Value" investment that combines the legacy of Hitachi engineering with modern energy efficiency standards.
