Despatch industrial ovens are very reliable and because of that we often forget that regular
maintenance is still required. Keeping the oven clean and inspecting components regularly will extend
the life of your oven, keep your oven safe, and reduce unexpected down time.
Electrical Components
Dirty electrical components do not dissipate heat as well and this will cause the component to heat up
and fail prematurely. Some dust and dirt can also be conductive, and this can cause heaters and
electrical circuits to short out and fail. Dirty fans and ductwork will affect air flow that will
affect oven performance and can affect oven safety. It is important to keep your oven clean.
Safety Features
Ovens have safety features like over-temperature limits, air flow switches, and purge timers. If these
safeties are out of adjustment, not working, or bypassed, the oven could be dangerous to operate. All
safeties should be checked on a regular basis.
Mechanical Components
Ovens have mechanical components that do wear out over time with use. Some of these components
include: Door seals, shaft seals, motors, latches, hinges, etc. Failure to inspect and maintain these
items can cause oven performance problems, loss of production or safety issues. For example: A ripped
door seal will cause oven chamber temperature uniformity issues. A cracked hinge could result in a
heavy door falling. Mechanical components need to be inspected to ensure proper operation of the
oven.
Oven Calibration
Most processes require accurate temperature control. Incorrect process temperatures can result in
failed processes and scrapped parts. Today’s electronic temperature controls and safeties are
very accurate, but calibration of the oven should still be checked on a regular basis to be sure correct
process temperatures are being achieved in the oven chamber.
