Overview

Middleby Marshall PS640G-CAV WOW Gas Impingement Conveyor Oven (Cavity Only, No Stand)

The Middleby Marshall PS640G-CAV is the cavity-only configuration of the PS640G WOW Series gas impingement conveyor oven, supplied without a stand for flexible installation into existing kitchen setups. Built in the USA from stainless steel throughout, it combines conduction heat and impingement technology to cook food up to 30% faster than standard conveyor ovens, making it a high-output solution for pizzerias and busy commercial kitchens.

A 76.5" conveyor belt moves food continuously through a 40.5" baking chamber, delivering consistent, hands-free results across every item. The WOW controller provides precise management of cooking parameters, while the integrated Energy Management System (EMS) reduces energy consumption during operation, lowering running costs without compromising throughput.

Key Benefits

• Cooks up to 30% faster than standard conveyor ovens thanks to the advanced impingement air delivery system combined with conduction heat, significantly increasing kitchen output.
• Continuous conveyor operation delivers a consistent, even bake from front to back without manual intervention, reducing labour demands during peak service.
• The cavity-only format allows the unit to be installed into an existing stand or custom benching, making it well suited to stacked double-oven configurations or space-constrained kitchens.
• The 'Cool Skin' safety feature keeps the external oven surface below 49°C (120°F), protecting kitchen staff from accidental contact burns during operation.
• Removable crumb pans, end panels, air fingers, and a folding conveyor belt assembly simplify routine cleaning and reduce maintenance downtime.
• The Energy Management System actively reduces energy draw during idle or low-demand periods, contributing to lower gas costs and a smaller environmental footprint.
• A wide operating temperature range up to 315°C (600°F) with a bake timer adjustable from 2 to 30 minutes accommodates a broad variety of menu items beyond pizza.
• Compatible with both natural gas and LPG, giving operators flexibility across different site requirements.
