3. Theory of Operation
3.1. The LAC-7 Series Oven
The LAC-7 high-performance bench-top oven
uses digitally-controlled, horizontal recirculating
airflow to ensure uniform temperatures
throughout the oven for fast-processing (Figure
2). A high-volume fan circulates air through
perforated, stainless steel walls to create a
constant horizontal airflow across all sections of
the oven (Figure 3). The result is proven
reliability in demanding production and
laboratory applications such as curing, drying,
sterilizing, aging and other process-critical
procedures.
The LAC-7 oven is especially useful for testing,
preheating, sterilizing, drying, aging and curing
along with other production applications. The
overall result is efficient productivity under strenuous conditions. 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 (located in rear of oven) as it
distributes exhaust air and protects the exhaust opening from
being completely covered.
