Studies: Resin Dryers - Dos Manos
Dos Manos, Royal Oak, MI
- Energy Cost
- Electric "Demand
Dos Manos Technologies, a minority-owned company, is located in a newly
built injection molding plant and manufactures injection molded components for
the automotive industry.
Dos Manos wanted
to expand its production but did not have the electrical capacity. That is when
they decided to install Conair gas-fired resin dryers exclusively.
The Dos Manos plant, built in 1998-1999, is a 40,000-sq.ft. facility.
The parent company and those in charge of the facility and equipment specifications
knew prior to installation that gas dryers would be less expensive and more efficient
to operate than their electric counterparts.
All six of the installed Conair resin dryers have demonstrated their
dependability. The units have not required additional maintenance. Also more resin
can be dried with the gas resin dryer units, since they deliver more uniform and
efficient heat than electric models.
"Demand Charges" Eliminated
Use of natural gas engine-driven equipment also eliminates electric-demand
surcharges. Utility companies typically add these charges to electric bills during
normal business hours, especially during the summer.
The gas-fired resin dryers provide improved productivity by allowing
the processor to dry more material in less time with significant energy cost savings
over equivalent electric units. Gas dryers offer up to 80% or more energy savings
over electric units, depending on local energy rates, according to gas utilities.
Many new gas dryer designs incorporate microprocessors and computer integration
to optimize both the bed temperature and air flow rate and to also make in-line
measurements of the plastic's moisture content. Gas-fired dryers use advanced
burner technology, provide high efficiencies, low emissions and long life.
Dos Manos plant engineer, Ed Palmer says "I would recommend the
gas units. They dry the material and meet the application. If we need to add more
dryers, I'd add more of the gas units."
