Compressors Bring Oil-free Technology to Data Centers

Danfoss has expanded the capabilities of Turbocor compressors TTS and TGS with a higher saturated suction temperature (SST) operating range—helping OEMs bring the benefits of oil-free technology to data centers operating at higher temperatures.

Danfoss has expanded the capabilities of Turbocor compressors TTS and TGS with a higher saturated suction temperature (SST) operating range—helping OEMs bring the benefits of oil-free technology to data centers operating at higher temperatures.

Allowances for data center cooling temperatures have risen steadily in recent years, thanks to new server technology allowing them to operate at higher space temperatures—giving operators greater flexibility to benefit from lower power, infrastructure, and operating costs. Danfoss is now helping chiller OEMs meet this evolving need without sacrificing reliability and efficiency by expanding the operating range of its Turbocor compressors.

Available on TTS and TGS compressors designed for air- and water-cooled chillers, the new high-SST option enables select Turbocor models to generate leaving water temperatures as high as 82 F, substantially reducing compressor load and power consumption.

This change enables OEMs to offer next-generation operators all the benefits that have made Turbocor oil-free compressors a choice for data center chillers, such as efficiency, accuracy, and long-lasting reliability with no performance degradation over time.

Turbocor compressors have the added benefit of both restarting quickly after a power outage and requiring a low start-up current, meaning they can better help to maintain the set temperature in uncertain conditions without putting strain on vital backup generators. In addition, Danfoss Turbocor compressors offer a 40 percent improvement in efficiency compared to fixed-speed screw compressors, with no performance degradation over time.

The newly equipped Danfoss Turbocor models are designed for use with A1 and A2L low-GWP refrigerants R134a, R515B, R513A and R1234ze.
