What is the typical screw compressor motor voltage?

The typical voltage for screw compressor motors in industrial refrigeration systems is often around 480 VAC. This voltage level is commonly used in North American industrial applications, making it the standard for many industrial equipment including screw compressors. This voltage range is suitable for enabling efficient operation of high-power machinery while ensuring compatibility with the electrical distribution systems within industrial settings.

While there are other voltage options listed, such as 440 VAC, 400 VAC, and 460 VAC, these may not be as prevalent in industrial refrigeration applications. For example, 440 VAC is closer to older standards and may not reflect the current standard used in most new installations, which tend to favor the 480 VAC standard due to its balance of performance and electrical regulation compliance. Thus, 480 VAC is recognized as the most typical voltage for screw compressor motors in this context.
