The buy is Audax’ third follow-on acquisition and brings CoolSys into Wisconsin, where CRM has 10 sites.

Source Refrigeration named Adam Coffey president and chief executive in November of last year. Coffey previously led El Segundo-based WASH Multifamily Laundry Systems, which manages laundry machines in apartment buildings. He integrated 18 companies there and left when WASH had 550,000 machines in 70,000 locations.

CoolSys says its companies have 1,200 employees and 2,500 customers in North America.
