INSPIRED INNOVATION

 TAD Walk-In and Truck-In Ovens

Designed for industrial process
versatility and dependability

Despatch TAD Truck-in/Walk-in ovens feature horizontal recirculating
air ow to ensure uniform temperatures throughout the oven. A high­volume fan circulates air through perforated, aluminized steel walls to
create a constant horizontal air ow across all sections of the oven.  e
result is proven reliability in demanding production applications, such as
aging, bonding, curing, drying,  nish baking and heat treating. Multiple
temperature operations are controlled by up to eight programs, with eight
ramp and soak segments in each program.

 e TAD 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. Data-logging functionality enables reporting
and analyzing and data  les can be exported via the controller’s USB port.

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.

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