Johnson Controls, the pioneer for smart, healthy, and sustainable buildings announced a partnership with its joint venture company, Johnson Controls-Hitachi Air Conditioning, to offer wide-scale distribution of its industry-recognized line-up of Hitachi horizontal scroll compressors in North America.

This offering aligns the innovative Hitachi scroll compressors with the strength of PENN®, a brand from Johnson Controls backed by more than a century of commercial refrigeration expertise. As a result, the ZS and DS series horizontal scroll compressors are now available to North American-based refrigeration equipment manufacturers through Johnson Controls sales representatives.

Low sound and vibration performance in a compact design

Hitachi ZS and DS series horizontal scroll compressors offer unique low sound and vibration performance

Hitachi is known for pioneering the world’s first scroll compressor. Hitachi scroll compressors continue the tradition of innovation with this latest release of environmentally friendly, low GWP refrigerant solutions.

Designed for the rigors of commercial refrigeration applications, Hitachi ZS and DS series horizontal scroll compressors offer unique low sound and vibration performance in a low height, low weight compressor profile. These features help facilities realize the OpenBlue Healthy Buildings promise through improved space optimization, energy savings, and remote operating capabilities.

performance and reliability

As refrigerated equipment machine compartments become smaller, horizontal scroll compressors are the perfect solution to save space, reduce energy consumption, and minimize noise and vibration,” said Bill Merritt, director of business development, at Johnson Controls.

Hitachi first introduced its horizontal scroll compressor in the early 2000s, and today, we are pleased to not only offer a product that delivers exceptional performance and reliability but has also undergone rigorous testing and continuous design enhancements.”

Unmatched flexibility and proven reliability

Horizontal scroll compressors play a role in enhancing sustainability and keeping refrigerated equipment up

Horizontal scroll compressors play an important role in enhancing sustainability and keeping refrigerated equipment up and running to ensure food, pharmaceuticals, and other perishable goods are maintained at the proper temperature.

They integrate seamlessly with Johnson Controls PENN portfolio of temperature, pressure, humidity, and fan speed controls as well as software and smart connected solutions providing remote monitoring, alarming and data-logging capabilities.

Advanced compressor features

The Johnson Controls-Hitachi Air Conditioning horizontal scroll compressor line-up delivers unmatched flexibility, proven reliability, and advanced engineering due to these features:

  • Flexibility: The compact footprint of the horizontal compressor allows for the reduced height of equipment machine compartments.
  • Reliability: The high-side pressure design eliminates the need for a thrust bearing and tip seals, reducing friction and improving the alignment of the scroll set. This results in reduced wear plus improved oil circulation rates and oil foaming elimination.
  • Improved sound quality: The innovative scroll compressor design generates lower dBA for a more pleasant environment.
  • Reduced vibration: Lower compression torque reduces overall cabinet vibration and pulsations, reducing potential damage to piping and other system components.
  • High efficiency: The unique high-side pressure design with direct suction delivers fewer compression losses and improved volumetric efficiency.
  • Refrigerant Compatibility: Available for use with environmentally friendly, low GWP refrigerants such as R448A/R449A and R290, as well as HFC refrigerant R404A.
  • Two series are available to North American-based refrigeration equipment manufacturers.

refrigeration and air conditioning applications

Johnson Controls-Hitachi Air Conditioning horizontal scroll compressors will be made available in phases. The first phase includes the ZS and DS series single-speed horizontal scroll compressors that range in capacity from one-half to three horsepower.

Phase two will include the availability of larger capacity vertical scrolls, and inverter-driven horizontal and vertical scroll compressors for both refrigeration and air conditioning applications.
