Energy Recovery Wheel General Cleaning
Routine maintenance of the Energy Recovery
Wheel includes periodic cleaning of the
Energy Recovery Wheel as well as inspection
of the Air Seals and Wheel Drive
Components.
Cleaning the energy transfer media will help
maintain
optimal performance. The
frequency of cleaning is largely dependent on
the application and air quality. Use
ASHRAE’s Classes of Air categories, to
create a routine cleaning schedule.
Class
1 air has low contaminant
concentration with inoffensive odor and
sensory irritation intensity.
Class 2 air has moderate contaminant
concentration, with mildly offensive odors or
sensory-irritation intensity.
Class 3 air has significant contaminant
concentration and significant offensive odor
or sensory-irritation intensity.
Class 4 air has highly objectionable fumes or
gases and potentially contains dangerous
particles, bio-aerosols, or gases at a
concentration high enough to be considered
harmful, not suitable for recirculation or
transfer to any other space.
