The Hitachi AVSY Series brings advanced Variable Speed Drive (VSD) technology to the air-cooled chiller market, providing a "High-Value" cooling solution for the evolving infrastructure of Bangladesh. By utilizing a modular approach, the AVSY series eliminates the need for expensive, dedicated chiller plant rooms, allowing for flexible rooftop installations that grow with your building's requirements.
Stepless Capacity Control & High Efficiency Equipped with Hitachi’s proprietary DC Inverter Scroll Compressor, the AVSY series delivers surgical precision in cooling. Unlike traditional chillers that operate in fixed stages, the AVSY offers stepless capacity control from 25% to 100%. With a 500-step flow resolution, the unit matches the building’s heat load exactly, resulting in an impressive IPLV of up to 6.06. For businesses in Dhaka and Chittagong, this translates to massive savings on monthly electricity bills, especially during part-load conditions.
Space-Saving Modular Flexibility Real estate and rooftop space are often limited in urban Bangladeshi projects. The AVSY units feature a compact footprint and require only a 0.5m gap between modules. Their modular nature allows for creative layouts, including "L", "U", "T", or "Z" shapes to navigate around existing rooftop obstacles like solar panels or water tanks. Furthermore, because each unit functions independently, the system offers built-in redundancy—if one module is undergoing maintenance, the rest of the system continues to cool your facility without interruption.
U-Shaped Air-Side Heat Exchanger To maximize heat rejection in high-ambient environments, Hitachi utilizes a U-shaped heat exchanger design. This increases the heat exchange surface area while minimizing the unit's physical size. The copper tubes feature internal threading to increase turbulence and heat transfer efficiency, ensuring the chiller maintains peak performance even during the intense 40°C+ Bangladeshi summer heatwaves.
Optimized Control Logic & Smart Management The AVSY series includes intelligent control logic that automatically rotates the operation of units in a modular configuration. This ensures even wear across all compressors, extending the overall lifespan of your investment. Each module is equipped with a 4.3-inch color control panel, and with ModBus/RS-485 communication as standard, the system integrates seamlessly with any modern Building Management System (BMS) for centralized monitoring.
A Reliable Investment for Modern Infrastructure Whether your project is a new healthcare facility, a shopping mall, or an industrial complex, the Hitachi AVSY Series offers the perfect balance of industrial stability and energy efficiency. Its ability to operate in extreme climates, combined with its high-precision water temperature adjustment (0.5°C accuracy), makes it the definitive choice for professionals who demand the best in climate control technology.
