M&R’s Sprint 3000 series dryers are known throughout the industry for efficiency, consistency, and value. The Sprint 3000 DHZ (patents pending) expands on that heritage with dual heat zones and belts that can operate separately or function together as one large dryer, there is simply no other dryer like it.

New inks and new printing methods such as DTG and Hybrid (combined screen & digital printing) with their vastly differing cure rates and temperatures, make the Sprint 3000 DHZ the complete choice to keep up with ever-evolving print technology. Job Recall™ allows operators to quickly change or re-call previous settings to best address the needs of production. 

A patent-pending center divider, combined with proprietary burner and air-flow controls, effectively let the Sprint 3000 DHZ function as two separate dryers. With independent belt speeds/retention times controlled by M&R’s AccuSet speed controller, and belt directions that can be changed from right to left, the Sprint 3000 DHZ is like two dryers in one. 

The easy-to-navigate icon-based touchscreen gives operators complete control of temperatures, belt speeds, and belt directions. The Job Recall feature makes it easy to load saved settings based on particular inks and substrates, ensuring the proper cure every time. 

The Sprint 3000 DHZ includes a tethered Ink-Temperature Probe that tracks and displays a real-time graph of the ink temperature as it passes through the dryer. Giving operators peace of mind that whatever ink/substrate combination being run is meeting the manufacturer’s recommended cure settings.

Features And Highlights


  • Heat chambers can be set at the same or different temperatures, and belts can be run in the same or opposite directions at different speeds
  • Can be converted on the fly from a single chamber into dual 91cm (36”) independent heat chambers
  • Functions flawlessly as a full-width split-belt 183cm (72”) single-chamber gas dryer
  • The large touchscreen simplifies dryer operations
  • Job Recall ™ allows operators to save settings for quick and easy recall


Additional Information

  • Enhanced airflow accelerates drying/curing
  • Four separate dedicated blowers (combustion, circulation, exhaust & outfeed hood exhaust)
  • High-volume circulation blower reduces energy costs
  • Integrated roll-down outfeed hood with exhaust blower
  • Stainless steel filter slides out for easy cleaning
  • CE Certified: Built to specifications established by the European Committee for Standardization® (CE)
  • CSA Certified: Built to specifications established by the CSA Group (models sold in Australia are AGA Certified: Built to specifications established by the Australian Gas Association)
  • UL Listed: Built to specifications established by Underwriters Laboratories® (UL)
  • Displays key operational information—including heat chamber temperature and retention time—and gives operators complete control of all screen printing conveyor dryer functions
  • Graphic display tracks dryer temperature and substrate temperature in real time
  • Job Recall™ allows operators to store operational parameters under operator-chosen alphanumeric names—and recall those named settings later for similar substrate/ink combinations
  • Maintenance Minder™ system alerts operators when scheduled maintenance is due
  • Temperature monitor issues visible and audible alarms when readings fall outside user-specified parameters
  • Tower light indicates when temperatures are within user-set tolerances
  • 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)
  • Automatic shutdown sequence keeps the blowers and belt running until the chamber has cooled
  • Crossover™ Belt System (U.S. Patent Pending: SN 15264277)
  • Driven by a reliable, heavy-duty, variable-frequency AC-drive motor
  • Patriot Belt™ with the SureTrak™ roller system features a heat-resistant, Teflon®-coated fiberglass belt with a red flexible bead stitched along one edge that rides in grooves machined into the large anodized aluminum rollers, providing the most precise belt tracking available (U.S. Patents Pending: SN 15194035 & 15265538)
  • Each Patriot Belt has a tracking bead matched to a corresponding SureTrak groove in the drive cylinder
  • M&R’s AccuSet retention-time belt-speed controller, coupled with M&R’s Patriot Belt/SureTrak belt-tracking system and Sprint 3000’s precise variable-frequency AC drive motors make it possible to change belt directions and speeds instantly without the need to re-track belts or recalibrate speeds
  • On Crossover Belt Systems, Job Recall allows users to create, store, and retrieve job recipes that contain heat-chamber temperature and direction and speed settings for each belt, making setup for repeat and similar drying scenarios a snap
  • Previously lost space between belts has been reduced and belts widened due to M&R’s superior belt-tracking methods
  • Adjustable infeed and outfeed openings
  • Air-cooled cabinet ensures long life for electrical components
  • Bearings are designed for high speeds and high temperatures
  • Circuit breakers allow easy reset
  • Cleanout access panels on the sides of the burner sections and drone modules simplify cleaning and maintenance
  • Exhaust Drawer/Creosote Catcher
  • Low-profile design makes it easier to see over the screen printing dryer
  • Burners are designed with excess capacity that far exceeds consumption rates under normal operating conditions
  • CoolSkin™ technology leaves the conveyor dryer skin cool to the touch
  • Fast curing rates and high product throughput maximize conveyor dryer capacity and minimize per-unit cost
  • Fuzzy-Logic controller ensures consistency by keeping dryer chamber heat within 1° of target temperature at the thermocouple
  • Heavy-duty thermal insulation prevents heat from migrating from the conveyor dryer into the workplace
  • Pressurized vector air knives provide consistent and uniform temperatures throughout the drying chamber
  • Sprint 3000 models are the most energy-efficient gas screen printing conveyor dryers in their class
