THEORY OF OPERATION
This section details the function and operation of assemblies and subassemblies on the
Despatch RFD1-42-2E Ovens. These ovens have the most effective heat distribution
system and the fastest processing time of any lab ovens their 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. The
Despatch RFD1-42-2E oven employs a higher volume fan than any competitive model.
The chamber can be densely loaded without interfering with the process. The RFD1-
42-2E air delivery temperature is within 1/2ºC of the number appearing on the digital
display. Also, fresh air intake is regulated by a damper slide located on the left side of
the oven. The exhaust rate is regulated by an adjustable control on the exhaust stack.
