With the launch of its D Series large desiccant dryers, with nominal throughputs from 600 to 5000 pounds per hour, Stamford, Connecticut-based Conair says it is simplifying its large dryer offering. Every model is built with desiccant wheel drying technology, a common touch-screen control and an expanded set of standard features.
“Every one of our new large D series dryers provides a far wider array of high-demand features as standard equipment, not options, and delivers them through a common control interface,” says A. J. Zambanini, drying products manager for Conair. “The result is a line of large dryers that are intuitively easy to understand and use, even without a significant amount of operator training.”
Zambanini continues, “With this introduction of large D Series dryers configured for central systems, our D Series line now extends from the Model D15 all the way through the Model D5000. We’ve done everything we can to provide continuity across the board so that buying, installing and using them will be very much the same no matter what size dryer we’re talking about.”
The largest dryers in the D Series feature the DC-C programmable electronic control, software and interface developed by Conair for drying applications. The standard DC-C Premium control system offers a color touch-screen user interface and a comprehensive set of features:
- temperature setback;
- dew point monitoring and control;
- real-time trending;
- seven-day auto-start/stop;
- library of customizable resin drying recipes;
- energy usage metering;
- audible and visual alarms; and
- Industry 4.0 enabled with remote control capability.
An energy saving Optimizer package adds a variable frequency blower drive, drying monitor probe, return air dew point monitor, volatile trap and process filter monitor to D Series dryers. These models get the DC-C Optimizer control, an augmented version of the Premium control, that uses the same interface and 7-inch color screen. “The Optimizer drying package is ideal for polyethylene terephthalate (PET) processors who need to manage high-throughput, high-temperature drying operations where its energy management features really pay off,” Zambanini says.
In the D Series, Conair says it has enhanced the desiccant wheel system, adding more precise rotational control to ensure optimal desiccant heating, cooling and drying performance.
