Features

Making normally opposing technologies of energy-saving and high-precision work together.
Our inverter controlled compressor responds to fluctuating workloads linearly, achieving high precision control while using the least amount of energy. Also, thanks to ORION’s original capacity control technology, high precision temperature control can be maintained even during low load situations that are normally difficult to deal with.
(User can choose between “High-Precision” and “Energy-Saving” modes in response to low-load conditions.)

As much as 65% Energy Savings Possible

Even compared with power saving ON/OFF type chillers, our DC Inverter control models offer energy savings of 30% at full load. A maximum 65% reduction in energy is possible when compared with temperature-stability-focused hot gas bypass types or proportional valve PID controlled chillers.

±0.1 ℃※High Precision Control

Adaptable to various applications that require high precision operation by using high-level temperature management.
Its extreme versatility makes it suitable for a wide range of applications, including precision production-use lasers, semiconductor manufacturing, analytical devices, and many others.

*When the load and ambient temperature are stable.

Wide Range Achieved

Fluid Temp. Control Range of 5 to 35 ℃ allows for wide-ranging applications. High temperature operation possible for piping condensation prevention, etc. Works in an increased range of ambient temperatures※from –5 to +43 ℃. (Water cooled types from +2 ℃.)This means our chiller can do its job under even harsher working conditions.

*If the ambient temperature could possibly fall down to 5 ℃ or lower, then measures should be taken to ensure that external piping does not freeze.

Built for Improved Ease of Use

The operation panel is set at an angle for improved easy of use and better visibility!

The water tank is located at the top for easier water supply, water quality confirmation, and cleaning!

The condenser duct filter is easily removed with a single touch. (Air cooled models only.)

Optional Equipment

An Abundance of Options with Multi-Choice Functionality

Operation and control functions, as well as fluid condition monitoring are all accessible from your PC via a single cable hookup.
To meet special needs of our users’ applications and operating environments, we offer many options to choose from, including remote controllers, heaters, communication software, and others.

*CE marking conformity available via built-to-order production.

Using Multi-Option Parameters, users can tailor the chiller operation to best suit their many needs and operating conditions.

Striving to make products that move you.

At ORION we have consistently developed customer-oriented “monozukuri” manufacturing techniques.
Since the time after the war when our company was established, we developed a wide range of products that had never before been produced in Japan, and we take pride in the fact that we have been able to shoulder our part as a driver of industry.
In recent years, our forte in air processors and energy saving technology has evolved even further, global environmental concerns regarding product development have advanced, and steady commercialization of these technologies has materialized.
And from now on, by continuing to offer products and service that delight our customers, we aim to create new value while consistently providing “Products that are No. 1 in the World”.
Our aim to provide “Products that are No. 1 in the World” will be realized by bringing excellent products to market that “move” people and building a bright future.
We at ORION strive to be a company that continues to provide products and service which instill trust in our customers across the globe as we also endeavor to offer maximum customer satisfaction.

Main Products

Precision Air Processors
With the key phrase being “Covering everything from whole-area air conditioning to localized air processing”, ORION offers new technology unmatched in the world: the PAP Precision Air Processor Series with Heat Pump Balance Control.

Vacuum Pumps
The history of the ORION dry pump started in Japan with the oil-free rotary vane vacuum pump. Thanks to its reduced noise and longer life, the dry pump has been indispensable in automation and labor-saving applications, playing an active and wide-ranging role for every kind of industry. In recent years, we were the first in the industry to release the inverter controlled oil-free vacuum pump.

Chillers & Dehumidifiers
Devices to heat or cool target heat sources through the circulation of fixed-temperature controlled water. A chiller and water supply equipment (water tank or pump) combined into a single unit in order to meet the needs of every application. Dehumidifiers are active in various industries from food-related businesses to service industries.

Compressed Air Related Equipment
For a supply of clean air that meets your needs that is also energy-saving, and oil and water separation treatment of compressed-air drain. Drain processing is good for the environment and also eliminates water-related trouble in pneumatic equipment.
