Who We Are

Chris Massetti, President

Since 1965 DONWIL has been the region’s first choice for 24×7 reliability in Power and Precision environmental systems for critical applications. Representing Liebert Corporation, the leading manufacturer in the world of critical HVAC and AC/DC power systems, DONWIL has assembled the most respected team of critical support systems experts in the industry.

When asked to get involved in a mission critical project, we don’t walk away after the initial sale. DONWIL continues to support customers both during and after the construction process, including all aspects of system procurement, start-up, commissioning, monitoring and maintaining these systems to ensure that they work as designed, and adapt as your company changes and expands.
