Airgas Inc. has announced a new marketing agreement with R.R Street & Co. Inc, a leader in the dry cleaning industry for 131 years, which will see the company’s custom-engineered liquid carbon dioxide gas supply system and ongoing liquid products offered by Street’s Solvair LLC, as part of its services package for customers of its groundbreaking new Solvair Cleaning System.

The Solvair process technology uses a process in which garments are cleaned with an effective and biodegradable cleaning liquid for exceptional cleaning power and uniquely, then dries garments without heat by gently bathing them in a succession of cool rinses with pressurized liquid carbon dioxide which removes the remaining cleaning liquid from the garments. When the liquid carbon dioxide is converted back into gas, the clothes are cool and dry.

Kelly Justice, senior vice president for Airgas Inc. and leading the design of the liquid carbon dioxide systems, commented, “With this agreement, Solvair will be able to offer its customers a cost-effective supply of consistent quality liquid carbon dioxide.”

“We have worked with Solvair to custom-engineer a more eco-friendly and efficient liquid carbon dioxide gas supply system that will work with this revolutionary cleaning process. It also includes telemetry and on-site monitoring to ensure safe and reliable supply. Airgas has the resources to provide both engineering expertise and liquid carbon dioxide to Solvair customers nationwide,” added Justice.

According to Street, this revolutionary technology is environmentally friendly, gentle on delicate fabrics, and removes a wider range of stains and soils than any other available process. The company has installed its first Solvair unit in a dry cleaning establishment in Illinois and will be adding units in New Jersey, California, and Louisiana over the next several weeks and throughout the US in 2008.

Ross Beard, president and chief executive officer of Street’s, spoke of the technology, “Solvair is a major advance in the science of cleaning garments and is the result of more than eight years of intensive research and development.”
