THEORY OF OPERATION
This section details the function and operation of assemblies and subassemblies on the
Despatch LAC Series Ovens. These ovens have the most effective heat distribution
system and the fastest processing time of any lab oven its size. They are especially
useful for testing, preheating, sterilizing, drying, aging and curing as well as other
production applications. Horizontal airflow with precision digital control delivers uniform,
fast processing. The overall result is efficient productivity under strenuous conditions.
The unique Despatch computerized design, moves forced convected heat through
perforated stainless steel walls. The air is recirculated with a high volume fan.
Despatch LAC Series Ovens employ higher volume fans than any competitive model.
The chamber can be densely loaded without interfering with the process. Air delivery
temperature is within 1 C of the number appearing on the digital display. Fresh air
intake is regulated by a panel-mounted damper control, while the exhaust opening is
fixed. The exhaust port, on the back of the oven, is covered by a hat bracket.

WARNING:
Do not remove the hat bracket as it distributes exhaust air and protects the exhaust
opening from being completely covered.
