INSPIRED INNOVATION

 RAD Cabinet Ovens

Proven reliability in demanding applications,
such as curing, drying and aging

Despatch RA cabinet ovens feature horizontal recirculating air ow to ensure
exceptional temperature uniformity throughout the oven. A high-volume
fan circulates air through perforated, stainless steel walls to create a constant
horizontal air ow across all sections of the oven.  e result is proven
reliability in demanding production and laboratory applications, such as
curing, drying, stress relieving, aging, and other process-critical applications.

 is oven is equipped with the Protocol 3™ microprocessor-based
temperature and hi-limit controller with large LCD display and real time
clock for auto start capability.  e LCD display shows temperature readings
along with clear, detailed information on oven status.  e data-logging
functionality enables reporting and analyzing and data  les can be exported
via the controller’s USB port. Modbus RS485 communications are included
for easy data access.

Notes: Uniformity figures are based
on a nine-point test conducted in
an empty oven after stabilization
period. Uniformity can vary slightly
depending on unit and operating
conditions. Minimum operating
temperature and cooling times are
based on 20°C ambient temperature
measured at the fresh air inlet with
the fresh air and exhaust dampers
fully open. Specifications are subject
to change without notice. If the
existing specifications differ from
yours, ask about our customizing
capabilities.

RAD models are not to be used with
flammable solvents, materials or
containers. If your process involves
flammable solvents please inquire
about our RFD models.
