LBB Series Oven Owner’s Manual Version 15 3. THEORY OF OPERATION 21 Theory of Operation 3.1. The LBB Series Oven The Despatch LBB Series ovens (Figure 2) 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.
LBB Series Oven Owner’s Manual Version 15 THEORY OF OPERATION 22 Warning! Do not remove the hat bracket as it distributes exhaust air and protects the exhaust opening from being completely covered. 3.1.1. Oven Theory The LBB Series forced circulating oven uses fan to circulate air through the chamber. A circulating oven is much more efficient and uniform oven than a gravity-convection oven due to the constant air movement.
LBB Series Oven Owner’s Manual Version 15 THEORY OF OPERATION 23 Table 2. Control Instrument Explanations.
