productivity and ease of operation are the deciding factors. These ovens are especially
useful for testing, preheating, sterilizing, drying, aging and curing as well as other
production applications. Gravity convected airflow with precision digital control to
deliver fast processing. The overall result is efficient productivity under strenuous
conditions. The LEB Series Ovens are precise and practical.
The unique Despatch design moves gravity convected heat through stainless steel
ducts on each side. The chamber can be densely loaded without interfering with the
process. Air temperature near the sensing element in the chamber is within 1°C of the
process temperature appearing on the digital display. For your convenience the fresh
air intake is fixed. The exhaust rate is regulated by a damper on the back of the unit.
