Desiccant Dryers Still the Gold Standard
Desiccant Dryers Still the Gold Standard
Patented, high performance dryer, hopper and optional loading systems. DRI-AIR’s PD Series eliminates press/extruder mounted drying hoppers for fast, safe material changes.
1 dryer, 2 hoppers, and 3 reasons why the H-PDII systems provide maximum flexibility: * Drying and processing from one hopper while pre-drying in the other; on-the-fly material changes eliminates downtime. * Co-injection and/or co-extrusion processes; run two materials at two different temperatures simultaneously. * Reduce valuable floor space; eliminate the need for a second dryer by positioning the portable system between two presses/extruders.
Multiple Hoppers with One Dryer * One dryer connects to multiple hoppers for a centralized drying system. * Dry different materials at each hopper as each has its own booster heater for temperature control. * Processors making one or two materials changes daily can justify the cost of a hopper bank in months.
Since 1974 Dri-Air has been the industry leader in proven desiccant dryer technology, offering the highest quality at competitive pricing. Our constant attention to detail and incredible response time has helped us sell thousands of drying systems worldwide. From 1 pound to 800 pounds per hour, we offer solutions to a wide range of industries from simple solutions to complex custom applications.
Desiccant dryers and drying systems with throughputs from 1 to 1000 lbs/hr. Arid-X dryer series is an industry standard dual desiccant-bed dryer that supplies a continuous -40 F dewpoint. HP4-X series offers a high-performance four-bed dryer that can achieve -100 F dewpoints. Both series include automatic regeneration. Arid-X and HP4-X series available in press-mounted, beside-the-press and portable models with one or two hoppers. Portable system features optional closed-loop loading system that includes single bag filter, controls and blower integrated on a common castered floor frame. Press-mounted hoppers are eliminated and replaced with a small, filterless receiver. Dual-hopper systems suitable for quick material changes and on-the-fly processing. Off-the-press drying/blending systems for virgin, regrind and colorants. Designed for quick changes and on-the-fly ratio changes. Placement of augers under hoppers eliminates hoppers full of premix. Microprocessor control features Safe-Temp regeneration (temperature based) as well as dewpoint and time based. Built-in -49 F dewpoint monitor and automatic seven-day timer. Also has capability for Ethernet connections for machine communication. CA series compressed-air membrane dryers are for smaller machines with drying hoppers from 1/2 to 60 pounds. Hopper mount, floor mount and multple hopper bank systems for fast material changes are available.
These are key trends in the many kinds of auxiliary equipment displayed at this month’s show. You’ll also see equipment designed to be virtually ‘foolproof.’
Novel parabolic tower design, unique heater configuration, and optimized airflow are said to maximize efficiency.
Quick-change manifolds let users switch hoppers or connect multiple machines to one hopper.
Latest personnel moves including updates from SPE, SPI, Engel, BASF, Dri-Air, Mack Molding and more.
The BAAM machine from Cincinnati Inc. continues to evolve with more pros involved so that by next year, the company will be taking orders for beta level and production machines.
The processors speak: Here’s how some smart molders and extruders tackle the vexing problem of resin drying.
Auxiliary equipment takes in a broad range of functions, from materials preparation to post-mold finishing.
Yes there are still molders drying with tray ovens. But this processor replaced the last few it had and has reaped some impressive energy-savings benefits.
There will be an extraordinary range of new auxiliary equipment on display at the show.
Portable material drying by truck is the concept behind an initiative launched last month by Poly Clean USA LLC, Charleston, S.C., with Dri-Air Industries.
By focusing on high-tech, quick-turnaround, turnkey solutions, Putnam Plastics has grown into a leader in the field of medical extrusion.
At least 16 companies introduced new dryers at the big show in Chicago. The new models span a range of drying technologies, but most sport features that save space and cost and make the dryers simpler and more reliable.
Visitors to the recent NPE 2009 show in Chicago were looking for materials handling equipment that could do more than dry, blend, or convey resins. It had to do those things while saving energy, providing faster and easier maintenance, speeding product changeovers, reducing labor cost, minimizing waste, and providing better value for money. The new products cited below addressed those needs and more.
The recent NPE 2009 show in Chicago saw the debut of dozens of new and enhanced robots for injection molding. The vast majority of the new models were all-servo types, though some economized by mixing servo and pneumatic axes. These new robots emphasized higher speeds, heavier payload capacity, longer reach, and more intelligent controllers that make programming and troubleshooting easier than ever. Telescoping arms and dual arms were very common among the new entries, as well.
Addressing the need for tighter cost control, several firms will offer new devices for energy monitoring.
All-servo, three-axis traversing robots from Sytrama in Italy are newly available in the Americas from Dri-Air Industries, Inc., E.
A new energy-efficient drying hopper from Dri-Air Industries Inc., East Windsor, Conn., features a non-conductive plastic outer cover that reportedly provides some heat insulation.
Is one type of resin dryer faster or more energy-efficient than another? That question prompts competing claims from suppliers—but very little concrete data. When one vendor performed controlled tests to get some answers, its results, published here for the first time, prompted further debate about the difficulties of making valid comparisons and the many complex issues involved in dryer selection.
Compressed-air membrane dryers are now available in a multi-hopper bank so that different materials can be dried at different temperatures.
A multiple-hopper drying system is said to be the first compressed-air unit that can simultaneously dry different materials at different temperatures.
