M&R's patent-pending Sprint 3000 DHZ (patents-pending) is a garment-curing game changer. It has a 183 cm (72") twin Crossover™ Belt System (U.S. Patent Pending: SN 15264277) and a proprietary shuttle system that can be used to create two separate heat zones. In essence, operators have the option of running two 91 cm (36") dryers in the same footprint as a standard 183 cm (72") Sprint 3000. The two zones can be set at different temperatures and the belts can be run at individually-selected speeds™in the same or opposite directions. And operators can switch between single-zone and dual-zone curing as needs dictate. Operators also have the option of heating only one zone, dramatically decreasing energy costs when both zones aren't required.
A variable-frequency AC-drive motor powers M&R's Teflon-coated fiberglass Patriot Belt™ with the SureTrak™ roller system (U.S. Patents Pending: SN 15194035 & 15265538). The red flexible beads stitched along the outside edges of the dual Patriot Belts ride in grooves machined into the large anodized aluminum SureTrak rollers. Those grooves reduce the gap between belts to a mere 0.95 cm (3/8"). M&R's AccuSet™ retention-time belt-speed controller makes it easy to duplicate settings and eliminates the need to convert feet per minute into the time substrates will spend in the heat chamber (U.S. Patent Pending: SN 13967564). In fact, belt and roller tolerances are so tight—and AccuSet speed settings so precise—that split belts running at the same speed in the same direction can function seamlessly as a single 183 cm (72")-wide belt. It's the most precise dryer belt tracking available.
Sprint 3000 DHZ's large color touchscreen control center features icon-based labeling and can display information and commands in multiple languages. It also displays real-time performance data, including temperature, temperature history, and output from the included temperature probe, which can be used to track substrate temperature as it passes through the dryer. Sprint 3000 DHZ uses cold air to reduce cooldown time by approximately 60%.
Job Recall™ allows operators to store operational parameters—and recall those settings for similar substrate/ink combinations. On the Sprint 3000 DHZ, Job Recall allows users to create, store, and retrieve job recipes that contain heat- chamber temperature and direction and speed settings for each belt. Other features include high-capacity circulation and exhaust blowers; an integrated roll-down outfeed hood with exhaust blower; adjustable entry and exit openings; and cleanout access panels on the sides of the burner sections and drone modules to simplify cleaning and maintenance. And M&R's Maintenance MinderTM System alerts operators when scheduled maintenance is due.
Available in liquid propane (LP) or Natural Gas (NG), Sprint 3000 DHZ dryers use high-performance burners. The burner system includes its own combustion air blower, and a high-volume forced air system quickly brings the dryer to the desired temperature. Process temperatures and set temperatures are controlled digitally. A fuzzy-logic controller keeps chamber heat within one degree of target temperature. A four-color tower light enables personnel to monitor the dryer's operational status while away from the control center. It shows when temperatures are within user-set parameters and issues visible and audible alarms when readings fall outside those settings. An automatic shutdown sequence keeps the blower and belt running until the chamber has cooled.
Sprint 3000 DHZ dryers are available in a wide variety of heat chamber lengths, including multi-burner models of 12.2 meters (40 feet) or more for slow-curing inks and a 6.1 meter (20 foot) heat chamber that requires only a single burner. Sprint 3000 dryers have the highest production capacity in their class and are the most energy efficient. CoolSkinTM thermal insulation prevents heat from migrating into the workplace and leaves dryer skin cool to the touch. Sprint 3000 Series is simply the world's most sought after line of dryers.
