White Oak Healthcare Finance, LLC announced it closed an incremental financing for SoClean, Inc., a portfolio company of DW Healthcare Partners. White Oak financed DW’s acquisition of SoClean in 2017.

SoClean is the only provider of fully automated cleaning devices for Continuous Positive Airway Pressure (CPAP) machines. CPAPs are used to improve health outcomes for those suffering from sleep apnea and other sleep disorders.

“SoClean’s products have changed the industry,” said White Oak Managing Director Ross Eldridge. “The company has been focused on scaling their operations and building a strong team for expansion. SoClean’s execution has been impressive and we are excited to continue supporting their growth.”

SoClean cleaning devices sanitize the CPAP mask, hose and reservoir without the need for disassembly, water or chemicals. DW Healthcare Partners is a private-equity firm focused exclusively on the health care industry.
