D. Energy Management Information
The PS360G reduces energy usage in two ways over most competitive ovens:
Modulating gas control
IDLE/ BAKING mode control (Energy Saving Mode)
The modulating gas valve within the oven controls pressure of the delivered gas to the burners to increase or
reduce the energy input as needed to maintain temperature instead of cycling a gas valve on and off. This is a
more efficient and accurate way of controlling the temperature and eliminates the losses associated with the
ON/OFF cycling control.
The PS360G like other Middleby WOW ovens has an idle mode that places the blowers at a reduced speed
during non-baking periods. Reducing the blower speed reduces the volume of air requiring heating and thus
reduces energy usage in these non-baking times. A photo eye sensor at the entrance side of the baking
chamber detects when food is placed on the belt and brings the oven up to the higher (baking) blower speed,
increasing the amount of convection air needed to cook products faster. When the product passes the photo
eye, the controller begins a preset timed period that insures the product will pass fully through the oven before
the oven returns to the IDLE mode. With this energy management scheme, the oven provides the increased
convection heat transfer needed for fast baking, without the energy penalty during non-baking times. This
functionality is fully automatic and requires no user interaction.
