Detailed Equipment Information
Guardian® II, the industry's most efficient, innovative, and affordable high-production graphic gas screen printing conveyor dryer, is available in belt widths from 122 to 213 cm (48" to 84"). Not only does it have the highest production capacity in its class, it’s also the most energy efficient. Heavy-duty thermal insulation prevents heat from migrating into the workplace; CoolSkin™ technology leaves the dryer skin cool to the touch; and exhaust gasses heat incoming air. Fast cure rates and high product throughput maximize dryer capacity and minimize per-unit cost.
Available in liquid propane (LP) or Natural Gas (NG), the high-performance burners are designed with excess capacity that far exceeds consumption rates under normal operating conditions. Separate blowers control combustion, circulation, and exhaust. A high-volume forced air system quickly brings the 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.
Guardian II features M&R’s Teflon-coated fiberglass Patriot Belt™ with the SureTrak™ roller system (U.S. Patents Pending: SN 15194035 & 15265538). The red flexible bead stitched along one edge of the Patriot Belt rides in grooves machined into the large anodized aluminum SureTrak rollers. It’s the most precise dryer belt tracking available. Entry and exit openings are adjustable. Digital speed readout makes it easy to duplicate settings. M&R’s automatic shutdown sequence keeps the blower and belt running until the chamber has cooled. Guardian II options include high speed conveyors; split belt conveyors with independent variable speed drives and direction; Switchback™ & Vitran II™ UV Curing Modules; and ambient air and refrigerated air cooling units.
For over 30 years M&R has helped countless screen printers realize their dreams by supplying them with innovative screen and digital printing products that stand the test of time. We have the right solutions, from pre-press to product finishing, for shops of all sizes. M&R equipment is designed and built with a commitment to quality, durability, and innovation, and is backed by unrivaled 24-hour service and support.
