Theory of Operation
Utilizing technology that combines Convection and Hot Air-Impingement along with Microwaves, the ARX-MRX
family of High Speed Combination Ovens rapidly cook food without sacricing quality in a small footprint. The
controls allow either programmed or manual cooking to coordinate air velocity and microwave production as needed
to meet the cooking requirements of the specic product. The on-board catalytic converter allows for ventless
installation.
Sequence of Operation
The oven is turned “ON” and allowed to come up to the programmed cooking temperature.
With a Menu Item loaded into the oven cavity and the door closed, the operator can either select from a list of
preprogrammed menus or input manual cooking instructions.
There are cooking stages that can have di󰀨erent levels of microwave energy and impingement air velocity.
Once initiated, the oven’s Controller will signal the Magnetron circuit to operate from 0 to 100% by modulating the
circuit on and o󰀨 (or on 100%) based on the program. Simultaneously, the Controller will regulate the Convection
Blower’s speed from 0 to 100% based on the program. At the end of each cooking stage, the oven can change to a
di󰀨erent microwave level and/or blower speed.
During these cooking stages, the oven controls the cooking temperature by energizing and de-energizing a heating
element.
