INTRODUCTION
Temperature Class
•
The oven is IECEx 60079 temperature class 2 equipment (T2), including under UL, CSA,
and ATEX Differences.
•
The oven is also UL Class 1 Division 2 temperature class 2 equipment (T2).
These classifications allow a maximum internal surface temperature of no more than 300°C
(572°F ). The maximum target temperature setpoint this oven can be set to 200°C (392°F) .
Hottest Internal Surface Temperature
Hotspots exceeding the temperature displayed on the oven control panel will form on the walls,
ceiling, and floor of the oven chamber while the oven is heating. The oven is engineered so these
hot spots never exceed the displayed temperature by the following amount:
•
+100°C (+212°F)
Maximum Process Temperature
A safety interval must be maintained between the hottest baking process temperature setpoint and
the ignition point of flammable material in the oven chamber.
•
The highest baking application or process temperature setpoint must stay at least 125°C
(257°F) lower than the auto-ignition temperature of the flammable material.
Data Plate Markings
The hazardous location markings on the unit data plate are the ultimate indicators of whether the
oven is compatible with your hazardous location zone and materials type. Always check the data
plate prior to installing the oven in a hazardous location.
