With so many coils in so many buildings, this creates an enormous risk of flooding out our buildings when not monitored. The pressure relief valves at every bend in Cooney coils self-seal, re-seat themselves, thereby containing the remaining chilled water in the coil that, in turn, protects the chilled-water pumps from burning out and protects Bldg 4 from flooding with chilled water.

c. Rupture discs are only for pressure applications and do not respond to freezing conditions in the coil unit. When freezing occurs the unit must be shut down, de-iced and then repaired. This does not happen with the Cooney coil. The Cooney coil freeze-block valves sense temperate changes and discharge a controlled amount of water as a coil begins to freeze to prevent the metal coil from splitting or rupturing and then reseats to prevent flooding.

3. MARKET SURVEY

Market research was performed via web searches of coil manufacturers. While non- Cooney brand components will function in the system, Cooney brand name products are essential to the Government’s requirement, as evidenced in Section 2 above.
