Power Plant Reconditioning

When a large power company in Casa Grande, Arizona reconditioned two of their 740 Megawatt coal fired power plant units, Polygon provided dehumidification, holding conditions at less than 30% throughout the maintenance lay-up of the two units. Polygon worked with the lay-up team to engineer this massive project from beginning to end. The team effectively brought the plant back online as scheduled.

Temporary Cooling During a Retrofit

Polygon provided temporary cooling for the retrofit of #1 and #2 turbines on a 900 Megawatt BWR Plant. Heat build-up during these shutdowns can create schedule delays due to the acclimation period for workers (as required by heat stress safety procedures). Polygon provided chillers and air handlers utilizing an elaborate labyrinth of duct to effectively cool the turbine floor, creating a safe and comfortable environment for plant personnel. In the end, the shutdown came in on schedule and under budget.

Generator Lay up

A 1,200 Megawatt PWR in Burlington, Kansas regularly utilizes Polygon to provide temporary dehumidification to lay up their generators. Polygon uses desiccant units to create an environment that eliminates the threat of corrosion in their turbine and generator units. This passivation procedure reduces costly maintenance and startup costs when the plant goes back on line. Polygon provides a complete turnkey package, ensuring stress-free and successful results.
