3. Theory of Operation
3.1. The LBB Series Oven
The Despatch LBB Series Ovens (Figure 1) effectively distribute heat with a processing
time among the fastest of any lab oven its class. LBB Series Ovens are effectively used in
testing, preheating, sterilizing, drying, aging and curing as well as other production
applications. The LBB Series Ovens incorporate forced circulating airflow with precision
digital control to deliver fast processing. The overall result is
efficient productivity under strenuous conditions.
The LBB Series Ovens are precise and practical. The unique
Despatch design moves convected heat through stainless steel
ducts on each side of the oven (Figure 2). The air is circulated
with a high volume fan. The LBB Series Ovens employ higher
volume fans than any competitive model. The chamber can be
densely loaded without interfering with the process. For your
convenience the fresh air intake is fixed. The exhaust rate is
regulated by a damper on the back of the unit.
