Moisture is the enemy of precision molding. If you're processing hygroscopic resins like nylon, polycarbonate, or ABS, a desiccant dryer is not optional-it's the difference between consistent parts and defects like splay or voids. But the buying decision isn't just about whether to dry; it's about choosing a system with the right capacity, portability, and control for your specific shop. That's where the Novatec NDB-15 Dual Hopper Desiccant Resin Dryer enters the picture.
Quick Verdict
At $2,750, this used Novatec NDB-15 combines two 30-lb drying hoppers, a touchscreen controller, and a mobile cart in one focused package. It's a capable choice for injection molding operations, prototype shops, and R&D facilities that process engineering plastics in moderate batch sizes.
Who It Suits
The NDB-15 is aimed at molders who need dependable drying for engineering-grade materials without dedicating a permanent footprint. The description calls out injection molding, prototype work, medical, aerospace, electronics, and R&D. If you're switching between nylon, polycarbonate, ABS, acetal, LCP, PEEK, PPS, TPU, or PET/PBT, the dual-hopper design lets you keep two materials ready at once, or dry one resin while staging another. The mobile cart adds a layer of flexibility that fixed dryers don't offer-you can position it exactly where the press needs it.
What Stands Out
The dual hopper setup is the headline feature. Each hopper has a nominal 30-lb resin capacity, so you get a combined 60 lbs of drying space. The touchscreen controller brings modern operation to a pre-owned machine, simplifying setpoints and monitoring. Power requirements are 115V single phase, which makes it easier to fit into smaller shops and labs that may not have three-phase power available. The unit is described as clean industrial condition and ready for production, meaning it's intended for real shifts, not bench-scale experiments.
The resin list is broad: nylon, polycarbonate, ABS, acetal, LCP, PEEK, PPS, TPU, PET/PBT. That covers everything from everyday thermoplastics to high-temperature engineering materials, making it a versatile tool for facilities that process multiple resin families.
Meaningful Trade-offs
This is used equipment, so it arrives with a pre-owned history. The 30-lb-per-hopper nominal capacity is a real constraint if your runs are measured in hundreds of pounds per hour; this is more of a job-shop or auxiliary dryer than a primary production dryer for large presses. Also, even though it runs on 115V, you'll still need to integrate it into your compressed air and resin handling setup-those connections are not part of the dryer itself. And while the touchscreen is a plus, any pre-owned electronics should be inspected before committing.
Novatec NDB-15 Dual Hopper Desiccant Resin Dryer - 30 lbs cap ea. - Mobile Cart
The Novatec NDB-15 is listed at USD 2,750.00. Its dual hopper system provides two 30-lb drying hoppers with a nominal resin capacity of 30 lbs each. The unit includes a touchscreen controller, runs on 115V single phase, and is mounted on a mobile cart. It is described as clean industrial condition and ready for production, and it's positioned for professional injection molding operations rather than hobby use. Choose it if you need a portable, dual-hopper desiccant dryer that can handle a wide range of engineering plastics. The limitation is its 30-lb per hopper capacity, which caps practical throughput at levels best suited to prototype shops, R&D labs, and smaller molding runs.
Bottom Line
If you process engineering plastics and need a dryer that can travel with your mold changes, the Novatec NDB-15 delivers dual-hopper capacity, a touchscreen controller, and mobile flexibility. Its 30-lb-per-hopper capacity and pre-owned condition demand a realistic look at your production scale, but for the right shop, it's a strong match.
