Emerson Apparatus, Gorham, ME, has
a newly-designed heat system for its
Speed Dryers which consistently maintains
a temperature range proportionally
across the entire working surface.
This eliminates any heat non-linearity
and utilizes the entire test surface. The
heat plate is made of a heavy, precision,
flat aluminum for accurate testing.
The Speed Dryer allows pulp and
paper mill labs to determine the moisture
content of pulp, paperboard, consistency
pads, newsprint, kraft,
groundwood and tissue.
The dryers are rugged and built for
There are two platen sizes – 14- x 24-
in. (Model 140) and 14- x 36-in. (Model
145) — to meet different testing needs.
The temperature ranges up to
150°C with 230°C available on request.
The dryers are regularly used with
the applicable TAPPI, CPPA, ASTM
and APPITA test methods.
Other new features include:
• Tight PID thermal control of the
heat plate so that desired temperatures
can be reached fast and accurately regardless
of varying load conditions;
• Multilayer ceramic insulation
maintains extremely high heat source
• Non-conductive cover handle eliminates
the transfer of heat and is now
cool to the touch;
• Digital set point controller and
heavy-duty, solid-state relay provide reliable
The heavy vented cover, hinged at
the rear, is fitted with a non-asbestos
breathable fabric cover pad that functions
as a dryer felt and presses the sample
or hand sheet firmly against the flat,
Emerson will continue to support its
customers with older speed dryer models
with parts, maintenance, and service.
