SPRINT 3000 D Gas Textile Conveyor Dryer

Product Description

The Sprint 3000 D (patents pending) gas textile conveyor dryer utilizes a stacked dual belt design, effectively doubling throughput while keeping a small footprint dimension. It is designed to address new inks and printing methods such as direct-to-garment (DTG) and hybrid printing (screen + digital printing) and their vastly differing cure rates, as well as traditional screen printing. The Sprint 3000 D allows operators to quickly adjust dryer settings to production changes and demands, meaning production planning no longer needs to be dictated by traditional multiple-press, single-dryer scenarios. Operators can simply change the independent belt speeds and run their jobs!

With an easy-to-navigate, icon-based touchscreen, operators have complete control of retention times, while 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 D utilizes an enhanced non-slip Patriot Belt™ conveyor belt for the upper chamber with a special textured surface that holds garments and piece goods in place as they travel on the incline conveyor section to the upper burner chamber. The lower belt is offered in a single or optional Crossover™ Belt configuration, which adds even more production versatility.

The Sprint 3000 D has all the same great features as the original Sprint 3000, like Patriot Belts, SureTrak™ roller systems, AccuSet™ heat chamber retention time, and the Maintenance Minder™ program that alerts operators when scheduled maintenance is due. Other features include high-capacity circulation and exhaust blowers; adjustable entry and exit openings; and cleanout access panels on the sides of the burner sections to simplify cleaning and maintenance. M&R’s CoolSkin™ technology, tight tolerance build quality, and thermal insulation prevents heat from migrating into the workplace, leaving the dryer skin cool to the touch.

Available in liquid propane (LP) or natural gas (NG), Sprint 3000 D dryers use a high-performance burner system that includes its own combustion air blower, and a high-volume forced air system that quickly brings the dryer to the desired temperature. Process temperature and set temperature are controlled digitally, while a fuzzy-logic controller keeps chamber heat within one degree of target temperature. A tower light shows when temperature is within user-set parameters and issues visible and audible alarms when readings fall outside those settings. An automatic shutdown sequence keeps the blower and belts running until the chambers have cooled.

The Sprint 3000 D expands on the Sprint series' heritage of efficiency, consistency, and value, making it the most compact and efficient Sprint dryer ever.

AIR HANDLING

• Enhanced airflow accelerates drying/curing
• High-volume circulation blower reduces energy costs
• Stainless steel filter slides out for easy cleaning
• Three separate dedicated blowers (combustion, circulation & exhaust)

CERTIFICATION

• 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)

COLOR TOUCHSCREEN CONTROL CENTER

• Displays key operational information—including heat chamber temperature and retention time—and gives operators complete control of all screen printing conveyor dryer functions
• 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 temperature is within user-set tolerances

CONVEYOR SYSTEM

• 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
• Driven by a reliable, heavy-duty, variable-frequency AC-drive motor
• 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—and raising or lowering dryer temperature by more than 3° C (5° F) during operation results in DynaBelt™ changing the belt speed to maximum (when raising) or minimum (when lowering) until the desired temperature is attained (U.S. Patent Pending: SN 15251547)
• 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)
• Special non-slip textured upper Patriot Belt™ securely holds garments on incline in-feed

DESIGN & CONSTRUCTION

• 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

ENERGY EFFICIENCY

• 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
• The ability to run differing temperatures top and bottom maximizes efficiency and reduces energy costs

HEAT CHAMBER

• Burners are available for liquid propane (LP) or natural gas (NG)
• Double-wall construction
• Galvanized steel interior
• Modular gas train simplifies maintenance

PRODUCTIVITY

• Production planning no longer needs to be dictated by traditional multiple-press, single-dryer scenarios. With the D, operators simply change the belt speed or upper/lower chamber temperatures that require different settings, giving greater flexibility and savings.
• Sprint 3000 models have the highest production capacity of any gas screen printing conveyor dryer in their class
