The routine maintenance requirements of all equipment need to be considered in the initial system design. If equipment is difficult to maintain, chances are it will be ignored, reducing the effectiveness and life expectancy of the equipment. The maintenance requirements of filters, blowers, and motors are well known, but the level of familiarity with energy wheels is not as high. Understanding and implementing maintenance requirements for energy wheels will improve performance, effectiveness, and the life of the wheel.
Creating a regular cleaning schedule is critical to maintaining the performance of the energy recovery wheel. The schedule should be based upon particles present in exhaust airstream, operating hours, and climate. The following guidelines may be used in determining the appropriate cleaning schedule for several applications.
