M&R's SPRINT 3000 Gas Screen Printing Conveyor Dryer

Sprint 3000 is the latest incarnation of the most innovative and dependable line of gas conveyor dryers in the screen printing industry. For over twenty years, M&R’s venerable Sprint Series has been the overwhelming choice of professional screen printers who demand quality, consistency, and efficiency in their equipment and in the output they generate. Sprint 3000’s large color touchscreen control center features icon-based labeling and can display information and commands in multiple languages. The control center displays real-time dryer performance data, including dryer temperature, dryer temperature history; and output from the included temperature probe, which can be used to track substrate temperature as it passes through the dryer. 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’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 (U.S. Patent Pending). It’s the most precise dryer belt tracking available. Other features include high-capacity circulation and exhaust blowers designed for maximum efficiency on a wide range of inks and substrates; an integrated roll-down outfeed hood with exhaust blower; adjustable entry and exit openings to fit a wide range of substrates; and cleanout access panels on the sides of the burner sections and drone modules to simplify cleaning and maintenance. M&R’s Job Recall™ feature allows operators to store operational parameters under operator-chosen alphanumeric names—and recall those named settings later for similar substrate/ink combinations. And M&R’s Maintenance Minder™ System alerts operators when scheduled maintenance is due. Available in liquid propane (LP) or Natural Gas (NG) versions, all Sprint 3000 dryers utilize exceptionally efficient high-performance burners 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. A 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.
