Smart Coil for
Unit Ventilators

Classroom Solutions

Unit Ventilators with Cooney Smart Coil Technology are the most reliable way to keep classrooms comfortable year-round without sacrificing performance.

When freezing conditions exist, Cooney Freeze Block valves deploy a small amount of fluid to prevent the coil from rupturing. The Smart Coil’s self-contained BMS shuts down the fan and close the louvers to prevent damage.
