System Construction
Configuration and Size
System dimensions are 53.05 +/- 2.0 inches high and 37.4 or 47.4 (extended width) inches wide. Pass line height
is 35.4 +/- 2.0 inches. Standard width systems are capable of handling up to 18 inch wide product on the patented
Edge Grabber™ Conveyor and up to 20 inch wide product on the mesh belt. Extended width systems can handle 28
inch product on the Edge Grabber™ and 30 inch on the mesh belt. The Edge Grabber™ conveyor width is manually
adjusted. Auto Width Adjust option is available. Product Clearance is 1.75 or 3.5 inches above and below the
product pass line depending on application requirements. Available Power Configurations for are 208Volt,
380Volt, 420Volt, 480Volt 3Ø Wye (5 wire) 50 or 60Hz.
System Construction
ETS Thermal Processing Systems are modular in design and incorporate 31.5, 63 and 94.5
inch module sizes. Manufacturing cost is minimized to create variable length thermal
processing systems which all incorporate the same robust design. Using this modular
design theory, ETS quickly and easily designs application specific products to meet
your need. System Controls are accessible from either side of the users assembly line.
ETS Thermal Processing Systems utilize unibody construction, making the stronger
than machines with large, heavy frames. Large Area Filters running the length of the
machine offer long life and on-the-fly replacement.
Components and Assembly
Modular Construction, as described above, decreases build cycles and manufacturing costs.
Most sheet metal components are used in other ETS products. All sheet metal parts are
14ga. or 16ga. cold rolled steel and all are designed, manufactured and finished at ETS.
The process cavity is completely constructed from 400 series stainless steel. Almost all
(90%) machined parts are designed and manufactured at ETS. Many components are inventoried
in sub-assemblies to decrease specific, final configuration lead times. Final assembly,
turn on, run, test and process test are conducted to exacting documented procedures to
verify performance, reliability and repeatability.
Wiring and Electrical Components
ETS Thermal Processing Systems™ ave several wiring harnesses, each of which is documented
and constructed to applicable industrial standards. The harnesses include voltage
distribution, controls, motors, and thermocouples. Within these harnesses, individual
wires are color-coded as:
Red = AC, Blue = DC low voltage, Black = AC Switch,
White = Neutral Green/Yellow = Ground
Shielded cables are used where applicable to reduce noise emissions and susceptibility.
All thermocouples are shielded with the shields grounded to the machine ground block.
For board protection from static electricity, static ground jacks are located near where
circuit boards can be accessed. In addition to the wiring harnesses described above, each
system™ has a high tempwire harness for the high voltage power to the heating elements.
Wherever possible, this harness is routed separate from the low voltage control wiring to
minimize electrical interference. The high temp wire harness is color-coded black for the
hot wires and light blue for the neutral wires. Neutral wires are labeled with 'N' near
the heater element termination. The modular electrical panel has an integrated heat sink
and is inventoried as a sub-assembly. All purchased electrical components are readily
available and meet industry standards. ETS offers a unique main power disconnect handle,
which may be accessed, and/or safety locked from either side of the process line. All
electrical access covers are labeled, require tools to remove and/or are safety
interlocked to the main disconnect handle. All electrical components and wires are
labeled and easily accessible. Emergency stop buttons are easily accessed from either
side of the machine.
