and control system. Any of these methods enables you to control drying temperatures, watch energy usage or trend data, set automatic starts and stops, monitor alarms or manage equipment maintenance information.” Engineered for efficiency and
durability, Conair says that all GasTrac heaters are built around a ceramic gas burner with a variable frequency blower drive that precisely regulates combus- tion air flow to minimise emis- sions and boost fuel efficiency above 85%. A stainless-steel heat exchanger isolates process air flow from combustion gases, assuring a continuous, contamination-free flow of drying air. GasTrac process heaters meet or exceed key industry requirements, including UL, AGA, CGA, FM, NFPA, and IAS. In addition, through the launch of its new D

Series large desiccant dryers with nominal through- puts from 600-5,000 lb/h (272-2,268 kg/h), Conair is simplifying its large dryer offering. The company says that 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,” says Zambanini. “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. Conair believes that our standard D Series feature package will meet the needs of 90% of our drying customers. For those who need additional
capabilities, the advanced options that remain have been pre-engineered to simplify ordering and speed delivery.” Conair’s large-dryer launch follows its 2018 introduction of re-designed small and medium- sized portable dryers that offer throughputs from 15-400 lb/h (6.8-181 kg/h). The smaller dryers are available in the dX Series of mobile drying/ conveying systems and the stand-alone portable dryers were the first to get the D Series designation.
“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,” says Zambanini. “We’ve done everything we can to provide continuity across the board so that buying, install- ing and using them will be very much the same no matter what size dryer we’re talking about.” Like the smaller models, the latest, largest dryers in the D Series feature the DC-C programmable electronic control, software and interface devel- oped specifically by Conair for drying applications. The standard DC-C Premium control system offers a 7-inch colour touchscreen user interface. Other features include: temperature setback; dew-point monitoring and control; real-time trending; 7-day auto-start/stop; library of customisable 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, says Conair. These models get the DC-C Optimizer control, an augmented version of the Premium control that uses the same interface and 7-inch colour screen. “The Optimizer drying package is ideal for PET processors who need to manage high-throughput, high-temperature drying opera- tions where its energy-management features really pay off,” says Zambanini. Also new in the D Series, Conair says that it has enhanced the desiccant wheel system, adding more precise rotational control to ensure optimal desiccant heating, cooling and drying perfor- mance. Conair says its desiccant-wheel technol- ogy eliminates the instability and maintenance headaches associated with loose-desiccant dryers
