S-Series Walk-In and Truck-In Ovens

Despatch S-Series walk-in ovens and truck-in ovens operate at up to 650°F and have exceptional uniformity. They feature high velocity uniflow airflow, meaning that the air moves both horizontally and vertically, offering exceptional temperature uniformity. Adjustable air distribution louvers direct heated air to the part and is then recirculated through the heater box and back into the oven for greater energy efficiency. Precise airflow pattern and directionality can be modified to suit specific parts. CFD (computational fluid dynamics) software can be used to simulate how various oven configurations will heat your tooling and parts to determine the best possible solution. Despatch walk-in ovens are available with a gas or electric heater and come standard with Class A (NFPA 86) flammable solvent handling capabilities.

Despatch walk-in ovens feature the Protocol 3™ microprocessor-based temperature and hi-limit controller with a large LCD display and real time clock for auto start capability. The LCD display shows temperature readings along with clear, detailed information on oven status. Protocol 3™ features three operating modes for quick and easy operation: Manual mode, Timer mode and Profile mode. The data-logging functionality enables reporting and analyzing and data files can be exported via the controller’s USB port. Lead-lag part temperature control to extremely tight tolerances is provided for curing applications. For the best curing results, the soak time should not begin until the part has reached the desired set point temperature.
