A Pressing Problem-solved
The team at Canfor had a problem with a twin roll press for which
there was no readymade solution. The answer was serial #1 of an
upgrade that greatly improves washing efficiency at a fraction of
the cost of a new press.

When Greg Hallas walks into Kelly
Parfitt's office, there is the usual friendly
banter, inquiries about family, and the standard question, "How's POW #1 running?"
You would think they've been longtime
Colleagues they are, even though they are
on different sides of the supplier-customer
relationship. But they have not known each
other all that long-just the length of one
upgrade project. Hallas is product manager for twin roll press services at Andritz
in North America. Parfitt is a project engineer for two adjacent Canfor mills in Prince
George, British Columbia.
"Suppliers throw around the word 'partnership' all the time," Parfitt says. "For me, a
true partnership requires both parties to have
something at risk and something to gain.
Both have to be committed to staying-even
when things get tough. The upgrade of our
post-oxygen wash press (POW #1) here was
a true partnership."
The risk for Canfor was that the upgrade
that Hallas was recommending had never
been tried before. The reward was greatly
increased washing efficiency, reduced chemical oxygen demand (COD) to the bleach plant,
and a very stable operation. All at a fraction
of the cost of a new press.
