Dual Heat Zone Gas Screen Printing Conveyor Dryer
- Functions flawlessly as a full-width split-belt 183 cm (72″) single-chamber gas dryer
- Can be converted on the fly into twin 91 cm (36″) heat chambers
- Heat chambers can be set at different temperatures and the belts can be run in the same or opposite directions
M&R’s Sprint 3000 DHZ (patents pending) is destined to be a garment-curing game changer. Not only can it function flawlessly as a full-width split-belt 183 cm (72″) single-chamber gas dryer, it can be converted on the fly into twin 91 cm (36″) heat chambers. The heat chambers can be set at different temperatures and the belts can be run in the same or opposite directions. Operators can switch between single-zone and dual-zone curing as needs dictate, and they have the option of heating only one zone, dramatically decreasing energy costs when both zones aren’t required. In essence, operators can run two 91 cm (36″) dryers in the same footprint as M&R’s standard 183 cm (72″) Sprint 3000.
Sprint 3000 DHZ is loaded with the features that have made Sprint 3000 the most technologically advanced gas dryers in the industry. A variable-frequency AC-drive motor powers M&R’s patent-pending Teflon-coated fiberglass Patriot Belt™ with the SureTrak™ roller system, the most precise dryer belt tracking available. In fact, the incredibly tight belt tolerances enable Sprint 3000 DHZ to run its two split belts at the same speed in the same direction to seamlessly function as a single 183 cm (72″)-wide belt.
M&R’s patent-pending 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. Job Recall™ allows operators to store operational parameters—and recall those settings for similar substrate/ink combinations. 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. M&R’s Maintenance Minder™ System alerts operators when scheduled maintenance is due. A four-color tower light enables personnel to monitor the dryer’s operational status while away from the control center.
