Wright Runstad	Nordstrom Medical Tower	Prime
Complete refurbishment and modifications of 2 cell cooling tower and related building energy upgrades. Located on a 16th floor rooftop, this BAC cooling tower serves a medical facility with critical 24 hour continuous cooling needs. More > The cooling tower shared a common sump and could not be shut down for refurbishment or maintenance. Crane or helicopter lifts were not an option for replacement of this system. After investigation, our team developed a plan to create two independently operational cells to provide redundancy and facilitate maintenance on one cell without total shutdown. Our team split the tower cells with internal partition wall fabrication and installed new return piping, internal isolation valves, make up, overflow piping, controls, and sensors—all while the tower remained largely on-line. Tower refurbishment including fill, 20% capacity upgrades, coatings, fan shaft, motors, VFD’s, and new distribution were accomplished during a partial cell shutdown. System Heating negotiated and managed financial participation by Seattle City Light as part of an energy conservation project that involved cooling tower work, valve and control revision to over 300 water source heat pumps, VFD installation on pumps and substantial building control revisions. Also, System field-tested a urethane/glass coating system for a large manufacturer on one tower cell for field observation.

Equity Office	Wells Fargo Building	Prime
Develop a rebuild package that would provide a lasting and quality solution to extend the useful lifespan of this equipment with minimal maintenance requirements. More > This work was performed on large 3-cell cooling towers serving a 50-story office building in downtown Seattle. The cooling towers were modified in the past with additional capacity upgrades and piping revisions performed by others. However, there was little record of the modifications available. Therefore, our team made physical investigation to determine the fill media and component details in order to quantify necessary material take offs. The owner’s objective was for System to develop a rebuild package that would provide a lasting and quality solution to extend the useful lifespan of this equipment as long as possible with minimal maintenance requirements. System performed extensive fabrication and installation of custom hand laid tank lining to the complete interior of this tower system. Internal stainless louvers were installed to minimize back draft of moist tower discharge, new distributions were retrofit and internal sand filtration piping was removed and replaced. System also, worked with building engineers to support operational testing to resolve flow anomalies caused by fluctuation of basin water levels during isolation of towers.

McKinstry Co.	The Westin Building	Sub Contractor
This 3 cell Evapco cooling tower had severe corrosion and was at the end of its service life. It was located on the rooftop of a 43 story office building. The building's cooling requirements had grown beyond the capacity of the tower. More > The cooling tower served critical equipment within the building, so total shut down was not feasible. To add to the complexity, the overhaul was scheduled concurrently with a major equipment and piping project performed by Mckinstry Co. As a result, the cooling tower cells were isolated and refurbished individually while the other 2 cells remained operational during construction. Services included: Analysis and preliminary testing, report of conditions and recommendations, removal of existing fill, drift eliminators, distribution piping and supports, support modifications and installation of additional fill layer, complete motor, drive and fan re-build with vibration analysis and dynamic balancing, application of protective coatings to corroded surfaces. (Note: the fiberglass liner installed 5 years ago was in excellent condition) Heavy sheet metal design, fabrication and installation for 6 fan plenum repairs.
