Get accurate blends, better mixing, faster material changes and increased
profits with Conair's TrueBlend Series Blenders. Steep-sided component
hoppers allow material to flow evenly and freely through vertical dispense
valves into the weigh chamber. Efficient mixing assures full integration of
all recipe ingredients. The fully enclosed cabinet design assures no pellet
spillage and clean operation. Standard convenient features such as wide
access doors on each main material compartment, a hinged access door
and removable components in the mixing chamber reduce downtime
during cleanout.
THROUGHPUT RATES TO 9000 POUNDS AN HOUR
The TrueBlend TB2500 series blenders
offer processors with large extruders or
central blending applications a superior
way to blend naturals, regrinds and
additives centrally or at the throat of the
processing machine.
The blender dispenses up to six materials
(depending on model) from respective
material compartments into a common
weigh chamber. The control determines
the correct weight of each ingredient
based on setpoints entered on the touch
screen display. Up to 1000 recipes and
250 resin names can be entered and
stored in the control.
Air solenoids and major electrical components are easily accessed through the
electrically interlocked main power box.
Choose between four, five or six component blender models. Options include an
integrated blender/loader control feature, a
flow control valve for central blending applications, material compartment drain
ports, and ethernet communications.
■
Blend accuracy to 1/2 of 1%
Colorant and/or additive weights are held to within 0.5% of setting. A
selectable Precision Additive feature is also available for additives. The microprocessor control automatically calibrates after every cycle and compensates
for variations in dispense method, resin bulk density or particle geometry.

■
Easy-to-use control
Intuitive 5.7 inch LCD touch screen control with full
color graphics allows quick and easy setup of
blender setpoints. All setpoints are displayed
simultaneously. Enter the percentages of the
blend on the touch screen display and the
blender does the rest. The system automatically weighs the recipe ingredients in the
proper sequence and maintains the correct blend
relationship. Any position can be identified as one
of the four material type selections adding flexibility to
your application setup.
■
Convenient, no-tools clean out
Easy access to all material contact points for fast and safe cleaning during
color or resin changes. Material compartment access doors, removable weigh
bin, mix agitator and mix chamber liner allow quick efficient cleaning. The
blender features a built-in material shutoff valve below the mixing chamber,
this can be replaced with the automatic flow control valve for remote and
central blending applications.

SPECIFICATION NOTES
* Maximum throughput rates are based on 35 lb/ft3 pelletized
material, using all standard valve sizes. Use of reducer
inserts will lower the rate shown.
Throughput rates are based on:
• A 4-position blender recipe of 50% natural, 40%
natural, 5% additive material and 5% additive material.
• A 5-position blender recipe of 50% natural, 20%
natural, 20% natural, 5% additive material and
5% additive material.
• A 6-position blender recipe of 50% natural, 20%
natural, 10% natural, 10% natural, 5% additive material
and 5% additive material.
†
The optional flow control valve will mount inside the
chassis in the space of the manual slide valve. Conair
recommends using the optional flow control valve when
mounting the blender on a stand, surge bin or hopper.
‡
Numbers in top view drawings represent hopper
positions.
Specifications may change without notice. Consult with a
Conair representative for the most current information.
