Electric Infrared Ovens - Continuous and Batch

BigRed logo 4D54



The BigRed 4D-V54 high production conveyor oven features a boost zone, zone-to-zone temperature control, and high-efficiency air flow mapping, achieving ultra-high rates and side-to-side curing uniformity, while cooling the chamber skin, reducing noise and preventing dust contamination.

This oven is equipped with a 54 in. (137.2 cm) wide conveyor belt, dual heating zones and four infrared heaters capable of curing flat or bulky items at high rates.

A high-powered boost zone surges ink temperatures past 300°F (149°C) within the first several inches of conveyor travel, maximizing dwell time at optimum curing temperatures and, in turn, conveyor belt speeds and oven output.

An air flow mapping system quietly draws 'make-up' air into the chamber's double-walled shell through filtered inlets along opposite exterior sides serving to cool the outer shell for safety, while preheating the incoming air.

An exhaust fan located below the center of the conveyor belt draws the preheated air downward at rates up to 700 CFM (19.8 CMM) over and through the belt, removing heat, moisture and contaminants from the chamber.

The 8 inch (20.4 cm) diameter exhaust fan outlet can rotate 360 degrees for easy connection to ductwork, and the control box can be located on the right (standard) or left side of the chamber.

Exhaust filters located on both sides of the conveyor prevent dust or other contaminants from entering the blower or exhaust stack. Cleaning all filters before or after each shift can be accomplished in one minute, ensuring the quality of product, and safeguarding the equipment and the shop environment.

Exhaust flow sensors with warning lights alert operators to a clogged exhaust line, clogged filter or blower failure. Other safety features include a light tower to monitor oven status, and a 'cool down mode' for powering down.

Dual digital PID temperature controls maintain accuracy to +/-1°F (+/-0.5°C). The heaters of the oven carry a 15-year warranty, and feature closely spaced coils that provide high-density, medium-wavelength infrared heat for maximum cure speed without cold spots.

A Teflon-coated fiberglass belt with alignment tracking system is standard. Stainless steel mesh belts for high-heat and/or sanitary applications are optional.

Modular expandability allows your oven to grow with you

The capacity (belt speed) of LittleRed™ X1D, LittleRed™ X2D, LittleRed™ X3D, EconoRed™ III Series, and BigRed™ 4D (shown) conveyor ovens can be doubled or tripled as new or when needs increase by simply adding one or two modular heating chambers and extending the conveyor belt. This eliminates the need to invest in a larger oven than you need at the onset, and avoids the high cost of purchasing a new oven when your needs increase.
