So, what does all of this information mean to you?
Ultimately, the only thing that should be of interest is the performance and the efficiency numbers. So, how
do you get that information? Good Luck!
Since there's no industry standard to measure dryer performance and efficiency numbers, manufacturers are able to make claims
without comparing "apples to apples". For instance, a company may claim to full-dry using only 1600 BTU's
per lb. of H2O removed. Without any industry standard, the customer needs more information to make good comparisons.
You should ask: To get the quoted 1600 btu/lb. efficiency,...
what is the size and material of the product being dried?
what dry load-weight is used?
what level of extraction is needed?
how
many lbs. of H2O are removed per minute?
You
may find that, in order to obtain the quoted efficiency numbers, this dryer will take much longer to dry than expected,
or you must use higher extract speeds than your washer/extractors can perform, or you don't process much of this
material so the numbers given are of little use for you and your laundry.
Though the above dryer specifications don't tell the real story about performance
and efficiency, they do tell you something. We know that forced-air burners are typically more efficient than the atmospheric
style. We also know that a modulating (proportional) gas system is typically controlled more precisely and should be
more efficient than a simple Hi Fire/Low Fire system. Futhermore, for improved
air-to-load access, the drying basket should be of ample volume and of ample diameter.
I leave it to the manufacturers to explain their reasons for using the design features and specifications that they
do.
NOTE: Most of these specifications are published
or were obtained directly from the OEM's. OEM's should feel free to contact me
and correct any of their information. I will certainly make any requested changes or add new models, as needed.
