Sapphire Technologies Takes on the Cooling Challenge Behind the AI Boom

Its new oil-free compressor platform aims to help chiller manufacturers meet rising data center cooling demands while improving performance in extreme temperatures

Cypress, California, 11 November 2026 – Artificial intelligence is changing how businesses operate, but behind every AI application is a growing network of data centers that needs enormous computing power and reliable cooling. As these facilities expand, managing the heat generated by thousands of servers has become a major infrastructure challenge. Sapphire Technologies is addressing this growing need with the launch of its new High Lift Oil-Free Compressor platform, designed specifically for the demanding cooling requirements of modern data centers.

The company has introduced a new compressor business line and is now accepting orders for its oil-free centrifugal compressors. Manufactured at its facility in California, the technology is designed to support air-cooled chillers used in AI data centers. The launch also provides chiller manufacturers with an additional US-based source of compressor equipment at a time when increasing demand is creating supply constraints across the industry.

Cooling is essential to keeping data centers operational. Servers generate considerable heat while processing information, and this heat must be removed continuously to prevent equipment from overheating. Air-cooled chillers offer an alternative to traditional water-cooled systems because they do not require evaporative cooling towers, which can consume large amounts of water. However, these systems face another challenge when operating in extremely hot environments.

As outdoor temperatures rise, conventional compressors can struggle to maintain cooling capacity and efficiency. This operating condition is known as high lift. Sapphire's new platform is designed to address this problem by maintaining performance at ambient temperatures of up to 140 degrees Fahrenheit.

The technology uses a two-stage centrifugal design powered by a high-speed permanent magnet motor and active magnetic bearings. These components allow the compressor to operate without conventional oil lubrication. The company designs and manufactures these critical components in-house, building on more than 25 years of experience with oil-free technology.

Another important feature is its modular design, which allows chiller manufacturers to integrate the compressor into their existing products. Each unit can support capacities of up to 8,000 tons of refrigeration. Its power electronics can also be configured for alternating current (AC) or direct current (DC) supply, including an 800 VDC model designed to work with the high-voltage electrical infrastructure being adopted by data centers.

Freddie Sarhan, CEO of Sapphire Technologies, explained that existing compressors were not originally designed for the demanding operating conditions created by today's data center expansion. The company developed the new platform to help address these performance and supply challenges.

The launch also builds on Sapphire's wider experience in energy and cooling technologies. Its FreeSpin In-line Turboexpanders recover energy from excess pressure in natural gas pipelines and convert it into electricity and cooling for data centers.

Sapphire is already fulfilling orders and expects to deliver its first commercial compressors by February 2027. Alongside the equipment, it also provides magnetic bearings, controls, power electronics, and custom engineering support.

As AI infrastructure continues to expand, dependable cooling will remain essential to data center performance. Sapphire's latest development reflects how specialized engineering can help address emerging infrastructure needs while supporting more efficient cooling systems.
