SFW Acquires On-Site Analysis

January 27, 2015 by John McNulty

Spectro Scientific, a developer and manufacturer of analytical tools and software for industrial fluids analysis and a portfolio company of SFW Capital Partners, has acquired On-Site Analysis. This transaction closed in November 2014.

On-Site Analysis (OSA) specializes in the development and manufacture of advanced fluids analysis hardware and software technologies, primarily for on-premise coolant, oil and lubrication testing for municipal and commercial fleet vehicles. The company is headquartered in Palm Beach Gardens, FL with a manufacturing facility in Marlborough, MA (www.on-siteanalysis.com).

“Since its inception, OSA has pursued a vision of moving the oil and lubrication testing process from large, centralized laboratories to the actual users of the analytical information. That strategy aligns perfectly with Spectro Scientific’s promise of enabling our customers to always make confident, knowledge-based decisions immediately and without the need of an expert operator,” said Spectro Scientific President and CEO Brian Mitchell.

Spectro Scientific, acquired in July 2011 by SFW, specializes in analytical instrumentation and software for industrial performance fluids analysis. It is one of the largest worldwide suppliers of oil, fuel and processed water analysis instruments to industry and the military. Industry clients include petrochemical, mining, power generation and water treatment companies as well as commercial testing laboratories.  Spectro Scientific is headquartered in Chelmsford, MA (www.spectrosci.com).

SFW Capital Partners focuses exclusively on analytical tools and related services companies, including providers of instrumentation, software, information and analytical services. SFW typically invests from $10 million to $75 million of equity in middle market companies that have up to $25 million in EBITDA. The firm has offices in Rye, NY and Hudson, OH (www.sfwcap.com).

Industrial Growth Partners provides equity capital to lower-middle market manufacturing and manufacturing services companies with revenues of $30 million to $100 million.

The firm was founded in 1997 and is based in San Francisco (www.igpequity.com).

“We are very excited about the completion of the Calder acquisition as it considerably strengthens Climax’s position in the worldwide valve repair and testing market. Now, in addition to our comprehensive line of valve repair machines, we can also offer customers valve testing and safety protection equipment that will enable them to accurately and safely confirm the integrity of both repaired and newly manufactured valves” said Geoff Gilmore, CEO of Climax. “Calder’s new Houston facility will also serve as an expanded Climax rental depot, giving customers in the region access to a broader range of portable machining and automated welding rental options.”
