CATALYTIC CONVERTER

The catalytic converter is installed in the return air

duct behind heater assembly. A qualified technician

must perform the removal or installation of the

catalytic converter.

IMPORTANT NOTE:

The catalytic converter can

be cleaned with TurboChef Oven Cleaner

and thoroughly rinsed with distilled water. Let the

catalytic converter air dry before re-installing. If

TurboChef Oven Cleaner is not available,

DO NOT

SUBSTITUTE – USE DISTILLED WATER ONLY

Due to the nature of most foods and the physics

governing the operation of the oven, grease buildup

downstream of the cook cavity is inevitable. A

strict cleaning regiment can solve a majority of the

problems; however, recirculation of undiluted grease-

saturated air is the main cause of downstream grease

accumulation and any associated residual flavors.

Airborne grease tends to collect and bake onto the

oven’s surface downstream of the cook cavity. Due

to the high operating temperatures of the oven, this

grease will start to rapidly decompose into deriva-

tive organic compounds.

These decompositional derivatives generally have

positive and negative effects on cooking. Shorter

chain derivatives add favorable flavor characteristics

to the food, while the higher order carbon chains

lend unpleasant flavor characteristics, such as bitter,

tarry tastes. The installation of a catalytic converter

greatly affects the grease handling and any residual

flavors which might build up over time. A properly

operating catalytic converter causes the conversion

of airborne grease into water, carbon dioxide, and

small amounts of nitrogen and oxygen. The catalytic

converter acts as a combustion chamber for airborne

grease. The catalysts present on the filter lower the

ignition temperature of the airborne grease from

approximately 700ºF to 450–550ºF (371ºC to

232–288ºC), allowing combustion to occur. The

operating temperature of the oven directly deter-

mines the percentage of airborne grease conversion.

A single pass of the air stream yields a 20–30%

improvement in air quality.

Problems with the catalytic converter are indicated

by a decrease in the effectiveness of browning (caused

by a reduction in airflow) or by flavor transfer from

one food group to another.

If you experience a problem with the catalytic

converter, contact a TurboChef qualified service
