Enerven Compression

In August 2005, Energy Spectrum acquired a majority interest in Enerven Compression (“Enerven”) from one of its prior owners. At the time, Enerven owned and operated a small rental compression fleet, and a third party compression maintenance business through its wholly-owned subsidiary Wesco. Energy Spectrum provided additional capital to Enerven to support its strategy of growing its rental compression fleet by acquiring and deploying new compression units. In April 2008, after having significantly grown the size of its rental compression fleet, Energy Spectrum sold its interest in Enerven to two institutional investors and existing Enerven management.
