Sprint® is the most venerated name in gas dryers, with more than two decades leading the industry in innovation, efficiency, durability, and affordability. And Sprint 2000 high-production screen printing conveyor dryers are worthy heirs to that tradition. Sprint 2000 models are available in a wide variety of configurations, with dryer belt widths from 97 to 183 cm (38" to 72"). Not only does each Sprint 2000 model have the highest production capacity in its class, each is also the most energy efficient. Heavy-duty thermal insulation prevents heat from migrating from the conveyor dryer chamber into the workplace, while CoolSkin™ technology leaves the dryer skin cool to the touch. Fast cure rates and high product throughput maximize dryer capacity and minimize per-unit cost.

Available in liquid propane (LP) or Natural Gas (NG) versions, all Sprint 2000 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. There are also separate blowers for circulation and exhaust, each designed for maximum efficiency on a wide range of inks and substrates. 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 (excludes Mini Sprint 2000). When readings fall outside those settings, a temperature monitor issues visible and audible alarms. The entry and exit openings are adjustable to fit a wide range of substrates. The large belt rollers are machined with a slight crown to ensure positive belt tracking. An easy-to-read digital belt-speed display makes it easy to duplicate settings. 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.
