– A wide range of systems for different business or building needs
- Gear drive models use a gearbox to drive the compressor and are available as fixed speed and VSD (Variable Speed Drive) models. VSD models are more efficient as they moderate the output of the system according to the required load.
- Direct drive models offer enhanced efficiency and reliability because the motor directly drives the compressor speed without use of gears. We offer both Asynchronous Motor drive models (D-GXVG/D-GFVG) and Permanent Magnetic Synchronous Motor drive (M-GXVG/M-GFVG), with Magnetic Synchronous drive models offering greater energy efficiency when operating at lower speed and therefore lower capacity.
- Magnetic bearing centrifugal chillers utilize the latest and most advanced technology in the industry - magnetic levitation technology achieves a frictionless, non-contact state for its components. Hitachi VM series use magnetic bearings to support the spinning rotor of the compressor and leverage centrifugal force to compress refrigerant gas. The compressed gas is then used to cool air or water, making the VM series an efficient and reliable cooling solution.
– Top-tier efficiency ensures remarkable energy savings
– Easy operation
– Integrate with BMS and VRF systems
– Excellent Coefficient of Performance (COP) at part load even in winter condition
– Robust quality and high reliability
- A refrigerant economizer added to the 2-stage compressor equipped with 2 impellers. Due to lower rotation speed of 2-stage compression cycle, the chiller can achieve higher compressor efficiency, lower noise and longer bearing life.
- Direct refrigerant cooling of the lubrication oil in the oil cooler, without the need for cooling water piping.
- Surge protection: 2-stage impeller enables stable operation even at low cooling load or under conditions where the water inlet temperature is high.
- Oil supply temperature control: the friction heat generated in bearings fluctuates based on the compressor speed. Therefore, refrigerant is used to maintain the oil at a consistent temperature, whatever the loading on bearings.
– Quiet operation
– Environment-Friendӏy Refrigerant
– Centrifugal Chillers for Commercial Spaces
