Chief financial officer Mirko Schueppel will also leave Evoqua Water Technologies, at the end of March.
The Evoqua Water Technologies board of directors has appointed AEA Investors LP operating partner Gary Cappeline as interim CEO and Mark Roos, formerly CFO of Unifrax LLC, as interim CFO.
Private equity firm AEA Investors acquired Siemens Water Technologies in January 2014 and renamed the company Evoqua Water Technologies.
“The board and AEA are committed to maximising the industry-leading talent, expertise and resources of Evoqua. To realise the company’s full future growth potential in its next chapter, the board agreed that moving forward new leadership would be helpful to the organization,” said Evoqua board chairman Martin Lamb.
“The board wishes to recognise the many contributions that Dr Loeffler made in integrating the Water Technologies business and preparing it for carve-out and divestiture. We thank him and wish him continued success,” Lamb said.
Interim CEO Cappeline, formerly president and COO of Ashland Inc, is a chemical engineer and has extensive water and industry vertical experience. He joined AEA in 2007 and has been involved with Evoqua since June 2013 as AEA’s due diligence co-lead.
