Keeping wax at an even temperature had become frustrating and costly for a paper manufacturer that was a customer of Pittsburgh-based Chromalox.
waxing system on the corrugated paper line at the Tennessee facility could not
reliably maintain the required 200°F (93°C) on both the supply and return lines,
causing downtime and slowing production. The supply lines fed rollers that applied
wax to the paper with the excess wax feeding back to the supply tank via return
lines. Maintaining the wax at the prescribed temperature was vital to line flow
and a consistent quality packaging product.
installed 500' of self-regulating heat tracing cable to maintain temperatures
on both the high and low side. Chromalox’s IntelliTrace heat tracing line-sensing
control panel regulates the line. Microprocessor-based, the touch-screen panel
allows programming, and monitors and regulates the high/low temperatures, while
providing a ground-fault alarm and trip monitor.
corrugated paper manufacturer realized multiple benefits: increased
productivity leading, greater profitability, more reliable performance and constant
monitoring to maintain that reliability.
