INSPIRED INNOVATION

 TA and TF Walk-In Ovens

and Truck-In Ovens

Designed for industrial process
versatility and dependability

 e TA/TF Truck-in/Walk-in ovens feature horizontal recirculating air ow
to ensure uniform temperatures throughout the oven. A high-volume 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.

For applications that include  ammable solvents or large amounts of
moisture removal we o er the TF series.  ese Class A ovens are specially
designed to meet NFPA 86 requirements.  ey include a pressure relief
panel, purge timer and exhaust fan.

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.
