Combining a 40-inch baking chamber and an extra-wide 32-inch belt with patented high-velocity Impingement technology, the PS640G cooks up to 30% faster and uses up to 30% less energy than traditional conveyor ovens. Featuring automatic energy-eye throttling and an advanced modulating gas burner, it delivers maximum high-volume throughput with the lowest operating costs in the industry.

Key Features:

  • Patented WOW! Oven™ Impingement Airflow — uses a high-velocity air delivery system that changes airflow inside the chamber, baking pizzas and food up to 30% faster than standard conveyor ovens without drying them out.

  • Automatic Energy-Eye System — an optical sensor at the conveyor entrance automatically reduces gas use and blower speeds by up to 30% when no food is on the belt. As soon as food is loaded, it returns to 100% cooking power.

  • Modulating Gas Burner Technology — a smart burner precisely adjusts flame height and energy output to the cooking load, preventing over-firing and maintaining extreme temperature stability.

  • Extra-Wide 32-Inch Belt & 40-Inch Chamber — the 40-inch (1016 mm) cooking zone and 32-inch (813 mm) heavy-duty mesh belt let kitchens place two large 16-inch pizzas side by side or run rows of bulk menu items.

  • Advanced Touchscreen Digital Controls — a digital panel manages multi-zone temperatures, exact belt speeds, energy-saving diagnostics, and reversible belt direction (left-to-right or right-to-left).

  • Triple-Stackable Space Saving Profile — heavy-gauge stainless steel and high-density thermal insulation allow up to three PS640G units to be safely stacked vertically, tripling cooking capacity on one floor footprint.

  • Toolless Removable Components — for fast commercial sanitation, the conveyor assembly, stainless steel crumb trays, and interior air fingers slide out without tools for easy deep cleaning. Includes a front-loading glass window with a cool-touch handle.

Specifications:

  • Energy Source: Gas-heated (Factory-configured for Natural Gas [NG] or Liquid Propane [LP]) + Low-amp Electricity (for touchscreen controls, sensors, and blower motors).
