Features and Benefits

Flexibility Icon

Application Flexibility

The low-profile compact footprint and lightweight design allows for a more compact equipment machine compartment.
Low Sound Icon

Low sound level and low vibration

The innovative scroll compressor design generates lower dBA for a more pleasant environment. Lower compression torque and discharge pulse minimizes cabinet vibration and pulsations, reducing the potential for damage to piping and other system components.
High Reliability Icon

High reliability and superior quality

The high-side pressure design eliminates the need for a thrust bearing and tip seals, reducing friction and improving alignment of the scroll set. This results in reduced wear plus improved oil circulation rates and the elimination of oil foaming.

High Efficiency Icon

High efficiency thanks to advanced technology

The unique high-side pressure design with direct suction delivers less compression losses and improved volumetric efficiency.
Innovation Icon


Hitachi is known for pioneering the world’s first scroll compressor. Today, Hitachi continues the tradition of innovation with this latest release of horizontal scroll compressors.
Refrigerant Icon

Refrigerant compatibility

Available for use with environmentally friendly, low GWP refrigerants such as R290 (propane) and R448A/R449A, as well as HFC refrigerant R404A.
