Electric Infrared Ovens - Continuous and Batch

BigRed logo 4D30



The BigRed series ovens are the largest and most powerful ovens, engineered for applications requiring high capacities.

Equipped with four infrared heaters (total 11,400 watts), they feature a boost zone that jets temperatures to over 300°F (149°C) within the first few inches/centimeters of conveyor travel, increasing dwell time at optimum curing temperatures for significantly higher belt speeds and output.

The BigRed 4D-V30 is economical to run, with an average cost of only $1.14 per hour to operate based on 10 cents per kilowatt hour. It locates intake fans below the roof of the enclosure, quietly drawing 'make-up' air into the chamber's double-walled shell through filtered inlets along opposite exterior sides, serving to remove airborne dust, cool the outer shell for safety and preheat the incoming air.

An exhaust fan located below the center of the conveyor belt draws the preheated air downward over and through the belt, discharging from the underside of the chamber at 500 CFM (14.2 CMM) through a 8 in. (20.4 cm) diameter outlet that rotates 360 degrees to accommodate the plant's ductwork.

Exhaust filters located on both sides of the conveyor prevent airborne dust and lint from entering the blower or exhaust stack. Preventive cleaning of all filters before or after each shift can be accomplished in one minute, safeguarding products, 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). Controls are located on the right side of the heating chamber as standard, or on the left side to accommodate the plant layout.

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

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 or under curing associated with conventional units.

Double or triple capacity by adding one or two additional chambers and extending the conveyor belt length, allowing you to double or triple conveyor speed and output depending on application. Ovens can be ordered as new with multiple chambers, or can be expanded on-site in the future when needs increase.

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.
