For Efficiency, Reliability, and Scalability
As Southeast Asia continues to accelerate its digital transformation, the demand for data center is surging. With the rising energy cost and global ambitious sustainability targets, HVAC providers have placed new demands on air conditioning systems, to deliver uninterrupted performance while optimizing efficiency.
Hitachi Cooling & Heating advanced chillers technologies are designed to focus on three pillars: energy efficiency, reliability, and scalability.
Our air conditioning systems offer a comprehensive portfolio of chillers equipped with advanced Direct Drive Inverter technology to support the core functionality:
Rapid system recovery – just 35 seconds after power failure to ensure swift recovery and minimal disruption.
Auto cooling control – intelligent response to varying environmental conditions.
In addition, low GWP refrigerants like R513A, R1234ze and R1233zd are utilized for enhanced efficiency while aligning with global environmental standards.
