Core Technologies

ORION's history begins in 1946, when post-war scars still remained. A big dream was embraced in a small town factory, and the challenges of in-house product development were taken on. Sound development was achieved through many cases of repeated trial and error.

Refrigeration Technology

Refrigeration Technology

Starting with the technology fostered in the refrigeration unit that stemmed from the development of Japan’s first milk cooling Unit Cooler, we have continued developing products for many areas, from the industrial chiller and the compressed air dryer (refrigerated air dryer) which met the needs of the times, and continue to develop products such as our Precision Air Processor that meet the needs of wide-ranging fields of today.

Vacuum Technology

Vacuum Technology

The history of the oil-free rotary vane vacuum pump begins with the ORION Dry Pump. Thanks to their reduced noise and extended lifespan, dry pumps are indispensable in automation and labor-saving improvements in many industries and they play an active role in wide-ranging fields from the printing industry to semiconductor manufacturing.

Collection Technology

Collection Technology

We have developed various grades of filter used to remove dust, oil, and even suspended bacteria from compressed air. Our research continues into raw materials that offer low pressure-loss and high performance filtering to meet compressed air cleaning needs.

Combustion Technology

Combustion Technology

In the over 50-year history of our Jet Heater, ORION has developed reduced-noise combustion technology. For this reason, our Jet Heater is used in many types of applications from concrete curing on construction sites, to heating of factories, schools, gymnasiums, and more. And we are continuing to evolve our concern for the global environment along with our pursuit of improved area-warming.

Temperature Control Technology

Temperature Control Technology

"Heat Pump Balance Control", which is built into our precision air processors, is the latest technology in our ultimate pursuit of energy saving, high precision air processing which is unparalleled in the world. The ORION Precision Air Processor is used where high-quality air is paramount, including semiconductor and FPD production processing, and is now in great demand in many other areas of production as well.
