PowerSystems International, Inc. ("PSI") was founded in 1995 as a New York Corporation, and moved to Natural Bridge Station, Virginia in 2002 to engage in the business of supplying Custom Integrated Mobile Power Systems ("CIMPS"). CIMPS are trailer mounted acoustically enclosed generator sets that are combined with environmental control units and rapidly deployable soft shelters to form self-sufficient, rapidly deployable command centers, field hospitals, or disaster relief shelters. PSI procures suitable components, properly sized for compatibility, assembles, and integrates them on trailers designed to PSI's and its customer's specifications. Additional equipment and supplies may be added as cargo. Purchasers of CIMPS include governmental, military, and private entities, both in the United States and abroad.

"The availability of a suitable building, the existence of significant technical talent in HVAC and related fields, and the opportunity to reduce manufacturing costs made Virginia and the Rockbridge area a logical choice. I am most appreciative of the assistance provided by Governor Warner and Rockbridge County."

- Louis Zak, President
