Need some advice/opinion on wheel selection from someone who has serviced the different types over the last 20 years.
Want the wheel to last the life of the equipment 15 years packaged DX & 25 years hydronic air handlers.
AirXchange claims 20+ year life, but, it is plastic & that makes me think bio-degradation starting in 5 years. Also claim silica gel is imbedded & won't lose its effectiveness, but, I kinda find that hard to believe given plastic bio-degradation. Have heard they are more likely to gunk up with particulate due to the turbulent airflow (flutter of plastic "fins") even if MERV13 filtration both paths.
Ceramic & fiberglass ? NovelAire ? Have heard that the small fibers crossing "fins" tend to collect debris even if MERV13 filtration both paths.
Aluminum wheels (Semco, Xetex, Heatex, etc.) seem like the no-brainer for the extra buck given that is what the coil fins in a unit are made of & no bio-degradation (& future recycling). Also hear about laminar airflow making it less likely to have particle impact/buildup.
Other question is molecular sieve vs silica gel for latent transfer. I know the silica gel is more effective, but, isn't that what we use in shoe odor eaters ? I have heard of "dirty sock" syndrome with silica gel. Definately don't want that. I have heard the fix is to rotate these at all times, which would seem to really waste energy when the energy transfer is going the wrong way. While I'm at it, 3 angstrom molecular sieve worth it for other than lab fumes ?
