Detailed Equipment Information
Sprint® 3000T is the most innovative gas conveyor dryer in the screen printing industry. It features three independent conveyor belts on three levels that deliver maximum drying capacity in a minimal footprint. In fact, Sprint 3000T manages to squeeze over 914 cm (30') of belt travel in the space required for a 366 cm (12') heat chamber. The infeed carries substrates to the top level and smoothly transfers them to the middle belt. The middle belt carries those substrates back through the chamber in the opposite direction before making another smooth transfer to the bottom belt. The bottom belt carries them through the heat chamber a third time before delivering them to the outfeed. Each level includes its own set of air knives, ensuring extremely consistent and effective heating of substrates. Sprint 3000T’s color touchscreen interface displays real-time dryer performance data, including dryer temperature and dryer temperature history. It also includes Job Recall™, which allows operators to store operational parameters under operator-chosen alphanumeric names—and recall those named settings later for similar substrate/ink combinations.
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). And M&R’s DynaBelt™ dynamic belt-speed controller shortens warmup and cooldown times and reduces overall energy consumption by automatically setting the conveyor belt to its minimum speed upon dryer startup and to its maximum speed upon dryer shutdown. In addition, raising or lowering dryer temperature by more than ten degrees during operation results in DynaBelt™ initiating a proportional decrease or increase in conveyor belt speed until the desired temperature has been attained (U.S. Patent Pending). Sprint 3000 T’s reliable, heavy-duty, variable-frequency AC-drive motor powers M&R’s Teflon-coated fiberglass Patriot Belt™ with the SureTrak™ roller system. The red silicone guide stitched along one edge of the Patriot Belt™ rides in grooves machined into the large anodized aluminum SureTrak™ rollers, keeping the belt where it belongs. It’s the most precise dryer belt tracking available (U.S. Patent Pending). Sprint 3000T also includes an integrated roll-down outfeed hood, cleanout access panels on the sides of the burner sections and drone modules to simplify cleaning and maintenance, And to help keep Sprint 3000T operating at peak performance, M&R’s Maintenance Minder™ System alerts operators when scheduled maintenance is due.
Available in liquid propane (LP) or Natural Gas (NG) versions, Sprint 3000T dryers utilize an exceptionally efficient high-performance burner with ample capacity. The burner system includes its own combustion air blower, allowing precise metering of the air-to-fuel mixture to achieve optimum efficiency. There are also two separate blowers for circulation plus an exhaust blower, each designed for maximum efficiency on a wide range of inks and substrates. The high-volume forced-air system quickly brings the conveyor dryer chamber to the desired temperature, speeding the start of production. Process temperatures and set temperatures are controlled digitally. Temperature consistency is ensured by a fuzzy-logic controller, which responds to ambient temperature changes by keeping chamber heat within 1° of target temperature at the thermocouple. A tower light shows when temperatures are within user-set parameters. When readings fall outside those settings, a temperature monitor issues visible and audible alarms. An automatic shutdown sequence keeps the blower and belt running until the chamber has cooled, minimizing or eliminating the need to monitor conveyor dryer shutdown. Sprint 3000T’s heavy-duty thermal insulation with CoolSkin™ technology prevents heat from migrating from the conveyor dryer chamber into the workplace and leaves the dryer skin cool to the touch. Fast cure rates and high product throughput—especially on water-based and other evaporative inks—maximize dryer capacity and minimize per-unit cost. Sprint 3000T is simply the most innovative gas conveyor dryer for screen printing available today.
