Key Features

  • Industrial 55-Inch Baking Chamber — features one of the longest continuous heating zones available in the commercial industry. The 55-inch ($1397\text{ mm}$) length ensures that food spends adequate time under heat even while the conveyor belt runs at ultra-fast production speeds, maximizing hourly throughput.

  • Extra-Wide Dual-Capable Conveyor — fitted with a wide stainless steel wire mesh belt (typically 32 inches or available in split-belt configurations) that allows multiple extra-large pizzas, trays, or bulk meat protein pans to be loaded side-by-side continuously.

  • Ultra-High Output Gas Burner System — driven by a high-capacity gas burner assembly that provides rapid heat modulation and instantaneous thermal recovery. It effortlessly counters the cooling effect of loading frozen, cold, or raw foods in rapid succession.

  • Patented High-Velocity Impingement — utilizes specialized top and bottom air jet fingers to strip away the insulating cold boundary layer around food items. This delivers intense, uniform cooking up to 4 times faster than deck or traditional conveyor ovens.

  • Advanced Microprocessor Dashboard — controls exact bake profiles, digital internal temperature settings, and conveyor pass-through speed. Features electronic self-diagnostics and a reversible belt option to integrate perfectly into automated production lines.

  • Triple-Stackable Industrial Insulation — constructed with dense, heavy-gauge structural steel and marine-grade insulation. Even with its massive footprint, up to three PS555G units can be safely stacked vertically to multiply factory output on a single floor grid.

  • Front Loading Window & Easy Sanitation — features a wide front glass loading window with a cool-touch handle for mid-cycle intervention, along with completely toolless removable air fingers, crumb trays, and a slide-out conveyor assembly for end-of-shift wipedowns.

Specifications
