| New D Series large desiccant dryers |
With the launch of its new D Series large desiccant dryers, with nominal throughputs from 600 to 5000 lb/hr (272 to 2268 kg/hr), Conair is dramatically simplifying its large dryer offering. Every model is built around proven desiccant-wheel drying technology, a common touchscreen control, an expanded set of standard features, and a focus on value.
"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. The result is a full-featured line of large dryers that are intuitively easy to understand and use, even without a significant amount of operator training," explains A. J. Zambanini, Conair's Drying Products Manager.
Conair's large-dryer launch follows its 2018 introduction of redesigned small and medium-sized portable dryers that offer throughputs from 15 to 400 lb/hr (6.8 to 181 kg/hour). The smaller dryers are available in the dX Series of mobile drying/conveying systems and the standalone portable dryers were the first to get the D Series designation.
Like the smaller models, the latest, largest dryers in the D Series feature the DC-C programmable electronic control, software, and interface developed specifically by Conair for drying applications. The standard DC-C Premium control system offers a big 7-in color touchscreen user interface and a comprehensive set of features that includes:
• Temperature setback
• Dew-point monitoring and control
• Real-time trending
• 7-Day auto-start/stop
• Library of customizable resin-drying recipes
• Energy usage metering
• Audible and visual alarms
• 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 PET processors who need to manage high-throughput, high-temperature drying operations where its energy-management features really pay off," says Zambanini.
RESINWORKS™
The powerful standard control in the large D Series line also opens up new, cost-saving control options for users of Conair's ResinWorks™ centralized resin-handling and pre-conditioning system. "When you combine a large D Series dryer with a ResinWorks sled (sleds contain multiple, temperature-controlled hoppers), you can manage the entire sled directly from the dryer. That means you can control or monitor drying temperatures, trending data, energy usage, auto-start/stop or other features for each hopper. There's no need for separate controls on each hopper." If a control is required or desired, an HMI can be applied to each hopper. This allows for individual control of each hopper locally but also unlocks more feature capability for the entire system.
