Stay cool and comfortable with Hitachi’s global Chiller expertise
Chillers are ideal for large commercial and industrial buildings due to their high capacity and energy efficiency, and they eliminate noise and refrigerant risks near occupied spaces. Hitachi offers a diverse range of Chiller systems with tonnage capacities from small (3-5RT) to large (3000RT), including Air-cooled and Water-cooled, compressor types of scroll, screw, and Centrifugal Chillers, and Absorption chillers. Hitachi has global manufacturing capabilities and provides worldwide services. In addition to Chillers, Hitachi also offers a comprehensive selection of airside products, including fan coil units and air handling units for space conditioning and ventilation.
A wide range of Chillers: Air-cooled, Water-cooled, Centrifugal and Absorption
Hitachi’s Chiller portfolio offers up to 4 different types of chillers, including Air-cooled Chillers, Water-cooled chillers, Centrifugal and Absorption chillers. The AVSY series, moducar air-cooled chiller, can connect to 16 units, with a total capacity ranging from 65kW to 2,064kW, making it perfect for medium or large spaces, while the absorption chillers are ideal for use in the processing industry and for district heating. Hitachi’s range of cooling and heating capacities is wide and can meet the needs of all customers, from small businesses to large industrial buildings. Additionally, for airside available countries, Hitachi offers airside products for Chiller systems, including Fan Coil Units (FCUs) and Air Handling Units (AHUs), designed to create a comfortable indoor climate and improve indoor air quality.
Chillers with efficient design and precise capacity control
As the technology leader in the market, Hitachi Chillers are efficiently designed with precise capacity control. Our latest air-cooled chiller AVSY is designed with a proprietary DC Inverter Scroll Compressor with intelligent VFD control logic, enabling precise capacity matching for building loads while reducing power input. The unit features COP up to 3.0 and IPLV of up to 6.06, while select models are also reversible, providing heating with a Heating COP of up to 2.93.
Enjoy the advantages of flexible installation and maintenance of Hitachi Chiller
Due to the wide range of Chiller types and capacities available, customers can always find the right Chiller to suit their AC needs, whether they have a plant room. Additionally, they can connect the chiller system to other equipment using our unique H-LINK wiring system which reduces the total length of wiring needed by allowing point-to-point connection between any chiller or indoor unit. Those integrated into a Building Management system can connect our chillers via ModBus or BACNET protocols.
Continually higher COP and IPLV, larger capacity and lower GWP
Our Fan Coil Units (FCUs) and Air Handling Units (AHUs) airside products can contribute to improved indoor air quality by filtering the air, providing adequate ventilation, controlling humidity and temperature, and proper maintenance.

The high performance of Hitachi’s Chillers guarantees consistent comfort
Hitachi Chillers are built to perform at a high level, providing consistent and reliable cooling. For example, our Air-Cooled Modular Inverter Chillers (AVSY) can operate in ambient temperatures from -15C (or -25C for Low Ambient models) right up to 43C and include a smart defrosting mode for cold climates. Our inverter centrifugal chillers (GFG-SIT/GXG-SIT/GSG-SIT Series) enable stable operation even when using a low water inlet temperature, because the motor speed control range has been extended through improvements in oil temperature supply and recovery. By operating using low-temperature water during cold seasons, very little energy is used by the compressor thanks to the inverter motor control and a high-efficiency economizer, boosting COP up to 22.4 under partial load1.
