Report
Summary
This contract is used to maintain mandatory monthly testing and water treatment programs for City-owned chillers and boilers that are in operation. The chillers and boilers are components of heating, ventilation, and air conditioning (HVAC) systems. The water treatment program prevents fouling of the systems due to scale formation, limits corrosion, biological growth, slime and other general fouling of all water surfaces, passages, storage tanks, basins, heat exchangers, piping, and associated equipment. The user Departments are responsible for City-owned HVAC systems and this contract provides required maintenance to the components of those systems.
