An infrared drying system
from Heraeus Noblelight has
helped DS Smith Tri-Wall to
improve corrugator capacity
of coated board at its factory
in Monmouth and
contributed to a reduction in
downstream waste as well as
a decrease in energy usage.

Some of DS Smith Tri-
Wall’s markets require packing
cases to be coated with an
acrylic coating, to aid water
resistance and to improve
cosmetic appearance.
Faced with the need to
increase output of coated
corrugated board, DS Smith
investigated ways of increasing
the running speed of the
coated board drying section.
Heraeus Noblelight carried out
on-site tests using portable
rapid response carbon
medium wave infrared heaters.

These proved successful and
a full-scale 56kW carbon
infrared heating system was
installed. This offers a total
heated length of 2500mm
and can be manually or
automatically operated. There
is a built-in facility to upgrade
the system to 70kW if required.
