INSPIRED INNOVATION
TFD Class A Walk-In Ovens
and Truck-In Ovens
For applications involving fl ammable
solvents or excessive solvent removal
Despatch TFD Class A ovens are speci cally designed to meet NFPA 86
requirements for applications that include ammable solvents or large
amounts of moisture removal. e oven comes complete with a pressure
relief panel, purge timer, and exhaust fan.
TFD 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.

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.
