Vastex BR4D-V30 DTF Conveyor Dryer - 105" (267cm) Long

BigRed® 4D Series dryers, available in 30-inch (76 cm) and 54-inch (137 cm) belt widths, are the largest and most powerful dryers designed specifically for DTG digital inks, as well as screen-printed plastisols, water-based inks, discharge, and DTF adhesives. These dryers are ideal for Kornit® and other high-volume DTG production facilities, as well as automatic screen-printing operations requiring high throughput and large-scale DTF printing. Their modular construction allows for seamless expansion by adding additional chambers and extending conveyor length as production demands grow.

The BR4D-V30 model, featuring a 30-inch (76 cm) wide belt and four 24-inch (61 cm) wide heaters with a total power output of 11,400 watts, is capable of curing 72 garments per hour when printed with DTG/digital white ink at a 2.5-minute dwell time, 216 garments per hour with water-based ink or discharge, and 475 garments per hour with plastisol ink or DTF adhesives.

The BR4D-V54 model, equipped with a 54-inch (137 cm) wide belt and four 48-inch (122 cm) wide heaters producing a total of 22,800 watts, cures 144 garments per hour with DTG/digital white ink at a 2.5-minute dwell time, 432 garments per hour with water-based ink or discharge, and 950 garments per hour with plastisol ink.

For example, a BR4D-V54 model configured with four heating chambers can cure 576 garments per hour when printed with DTG/digital white ink at a 2.5-minute dwell time, 1,728 garments per hour with water-based ink or discharge, and 3,800 garments per hour with plastisol ink.

Every BigRed 4D Series dryer incorporates a high-powered pre-heating zone that rapidly increases ink temperatures beyond 300°F (149°C) within the initial few inches of conveyor travel. This ensures maximum dwell time at ideal curing temperatures, optimizing conveyor belt speeds and overall dryer productivity.

To maintain efficiency and safety, air intake fans positioned below the enclosure roof quietly pull in ‘make-up’ air through filtered inlets along opposite exterior sides at rates up to 560 cfm (15.6 m³/min). This system cools the outer shell while preheating incoming air.

An exhaust fan, located beneath the center of the conveyor belt, draws the preheated air downward at rates up to 900 cfm (25.5 m³/min), directing it over the garments and through the belt to effectively remove heat, moisture, and airborne contaminants from the chamber.

For flexible shop integration, the 6-inch (152 mm) diameter exhaust fan outlet can rotate 360 degrees for easy ductwork connection, while the control box can be positioned on either the right side (standard) or left side of the chamber.

Exhaust filters on both sides of the conveyor prevent garment lint from reaching the blower or exhaust stack. These filters can be cleaned in under a minute before or after each shift, ensuring the protection of printed designs, equipment longevity, and a cleaner shop environment.

Exhaust flow sensors with warning lights notify operators of potential issues such as clogged exhaust lines, blocked filters, or blower failure. Additional safety features include a light tower for real-time dryer status monitoring and a ‘cool down mode’ for controlled shutdown.

Dual digital PID temperature controls ensure precise temperature regulation within ±1°F (±0.5°C).

The heaters in BigRed 4D dryers come with a 15-year warranty and utilize closely spaced coils to deliver high-density, medium-wavelength infrared heat. This ensures rapid curing without the cold spots or under-curing issues commonly found in conventional dryers.
