This compact digital heat-trace
controller offers versatility
The new ITC Series intelliTRACE controller
(photo) is designed for line- or
ambient-sensing heat trace applications
in hazardous (Class I, Division
2) or non-hazardous areas. Available
in single- and dual-circuit models, the
ITC features a high-resolution display
and may be used in either freeze-protection
or process-control temperature
applications monitoring all process
variables both locally and remotely. The
ITC is a microprocessor-based system
with solid-state-relay power control,
selectable soft-start program, current
load,
dual resistance-temperaturedetectors
(RTD) sensor input for each
circuit, and ground fault equipmentprotection
monitoring. There are three
user-selectable control modes available
on the ITC: manual, off or auto. The
ITC's compact enclosure facilitates
electrical connections for the heating
cable, the a.c. power, and the RTD sensors.
This controller may be used with
constant wattage,
mineral-insulated
or
self-regulating heat-trace cables.

This jet fuel analyzer enhances
safety through automation
The Alcor JFTOT 230 Mark IV (JFTOT
IV) is a new jet-fuel thermal oxidation
analyzer (photo) designed for increased
safety and simplicity. New safety measures
in this compact model ensure minimal
jet-fuel vapor-exposure to personnel
and the environment through the
sample and waste containers. The sliding
test door also prevents exposure to
the high-temperature heater-tube test
section. The JFTOT IV simplifies operational
capabilities through automation
of tasks, such as priming the pump,
monitoring sample flow and aerating
the sample. The JFTOT IV is listed in
Table 1 of ASTM D3241-13, " Standard
Test Method for Thermal Oxidation
Stability of Aviation Turbine Fuels, "
as an acceptable instrument model.

Draw, view and share molecular
structures in realtime
New ChemDraw and Chem3D apps
for iPad tablets (photo) provide mobile
access to robust molecular drawing
and viewing tools for use in education,
R&D and publishing. The apps feature
the unique Flick-to-Share tool, which
gives users the ability to rapidly share
molecular structures across mobile devices,
eliminating the need for emails
and cloud storage services. Chem3D
is a molecular viewer app where scientists
can explore structures in three
dimensions by using the touchscreen to
rotate, expand and contract models for
a clearer display of spatial properties.
Chem3D can display 3-D models of proteins,
DNA, crystals and assemblies in
many formats, such as ball-and-stick,
wireframe, space-filling and cartoon.

Use this vertical blender for lowshear
mixing or vacuum drying
This company's vertical blenders
(photo, p. 28) are used for low-shear
blending and vacuum drying. Compared
to other blender varieties, vertiNote
: For more information, circle the 3-digit number
on p. 56, or use the website designation.
cal blenders are gentler, allowing for
mixing of powders, pellets, granules
and fibers in delicate and abrasive
conditions. In vacuum drying operation,
the blenders can accommodate
slurries, wet cakes, pastes and flowable
solids. Requiring only low heat
to drive off moisture or solvents, vacuum
drying in a vertical blender dries
heat-sensitive materials without risk
of thermal degradation, while also
consuming less energy. The blender
features a mechanical arm that rotates
an auger around the conical vessel.
The auger turns on its own axis.
Spray nozzles may be installed for liquid
addition and coating purposes. -
