u PWE Series Truck-In Ovens
and Walk-In Ovens
Designed for High Temperature Industrial
Process Versatility and Dependability
e PWE Series is designed for high temperature industrial process
versatility and dependability. Typical applications include aging, bonding,
curing and heat treating. ey feature horizontal recirculating air ow to
ensure superior temperature uniformity and process reliability.
e PWE Series is great for higher temperature custom and modi ed
applications with a max temperature of 454°C (850°F). For applications
that include ammable solvents or large amounts of moisture removal, we
o er a Class A option. e Class A option is speci cally designed to meet
NFPA 86 requirements and includes a pressure relief panel, purge timer
and exhaust fan.
e PWE Truck-in oven uses 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. Each oven is shipped fully
assembled and wired to minimize installation time. Once the oven is in the
place, simply make the electrical power connections and turn it on.
