Touchscreen Technology in a Compact Wheel Dryer

Conair Carousel Plus™ dehumidifying dryers guarantee moisture removal from resins, regardless of moisture content. You can be assured your molded or extruded products will be unaffected by moisture content that can jeopardize their quality.

Equipped with highly efficient desiccant wheels, long-life tube heaters and powerful blowers, Conair D Series Dryers can be coupled with a single hopper for efficient resin drying up to 400 lbs/hr {181.4 kg/hr} or more. Or they can be connected to multiple hoppers, each equipped with their own heat source for efficient delivery of dry air in a central drying station configuration.

These D Series Dryers, models 150 through 400 offer a choice of full-color, high-resolution touchscreen controls, for the simplest, yet most sophisticated control over the drying of your valuable resin.

Advanced touchscreen controls

The 4-inch Plus, or 7-inch Premium DC-C control features trending, auto-start, password protection, predictive maintenance and an energy usage meter.

Reduced energy costs

The desiccant wheel heats and cools more easily than other drying technology saving you up to 50% on your energy bill. Fewer parts, lighter structural mass, less to heat, no cooling water needed therefore less wasted energy. Easily view power consumption on the DC-C control’s “Energy Usage Meter”.

Maximum uptime, maximum reliability, smaller footprint

With significantly reduced part count, easy access and less wear you can expect many years of trouble-free operation. The weight of the desiccant assembly has been reduced by 70%, the part count reduced by 90%. There are no more indexing bed plates, no more cumbersome 4-way valves and no more messy desiccant beads. Shift-after-shift this dryer will deliver the performance you need to stay up and running.

DC-C Control Features

  • 4-inch color touchscreen
  • Trending (dewpoint, temperature, heater on-time)
  • Auto Start/Stop
  • Password protected
  • Energy usage meter
  • Dewpoint monitor and control
  • Visual alarm
  • Air-to-air heat exchange
  • Predictive maintenance

Audible and visual alarm

A combination of a blinking red alarm light and a horn alert the operator to any shut down alarm.

Temperature setback

Automatically reduces the drying temperature to a lower standby mode when the machine throughput is reduced or stopped.

Dewpoint monitor & Dewpoint control

Monitor the performance of the dryer with a digital dewpoint readout of the drying air. Dewpoint control allows the dryer to maintain an operator-selected dewpoint level. This feature helps prevent overdrying of moisture sensitive materials such as Nylon.

Air-to-air aftercooler

Air-to-air aftercooler means no water hook-up is required for operation. An aftercooler is required to reduce the temperature of the return air from the hopper, which improves the efficiency of the desiccant. The new air-to-air cooler achieves drying efficiency at temperatures up to 375°F {191°C}, while saving water and simplifying installation.

Dryer Options

Volatile trap

For materials that give off plasticizer residue when dried, an optional Volatile Trap is recommended to demist the volatiles from the hopper’s return air and collect them prior to the air entering the desiccant. Volatile traps extend desiccant life, reduce maintenance and include a convenient drain spigot. Volatile trap requires the optional water-cooled aftercooler.

Precooler

For drying temperatures below 150°F {65°C}, an optional Precooler is required to remove the internal heat of the dryer for low temperature drying. Precooler water connections match those of the standard aftercooler as listed in the specifications section.

Process filter check

To conveniently monitor air flow critical for drying, the Process Filter Check option provides an alarm when the resin drying air filter is blinded, jeopardizing effective drying. Process Filter Check provides essential guidance to maintenance intervals.

Drying Monitor

Save time and money from the aggravation of improperly dried material. The Drying Monitor automatically monitors the heat profile inside your drying hopper with a 6-zone temperature probe, to protect resin from over or under-drying.

Communications

When connected to a network the controller on the network may read actual temperatures, change setpoints, read dryer status, and process and display this information at a central location. Ethernet communications are available on the DC-C Premium control.
