PROJECT SCOPE:

Kraft Replaced one of two computer room air conditioning units (CRACU) and air cooled condensing units (ACCU) at the Public Employes Retirement Association – PERA Building. Along with new HVAC units work included new refrigeration piping and roof curbs and drain pans. Other work on-site included installing cooling curtains to improve air distribution, and tinting windows to reduce solar impact to the space. Finned tube radiation was removed from the space and relocated below the floor to reduce heat load in the data room. Cap Electric, Kraft’s Sister company, performed the electrical work.
