BTG PROdry precision linescan thermal imaging is used by tissuemakers globally to troubleshoot Yankee issues under normal operating conditions, without the need for shutdown. Amongst the questions we can answer with a PROdry audit are:
Is chatter damage occurring due to a Yankee internal or steam system operating condition?
PROdry thermal imaging technology has been continuously developed over the last 16 years, with over 100 machines audited from most major tissue making groups, with many machines audited multiple times.
PROdry’s infrared analysis technology records a stop-action image of the Yankee over one revolution, synchronised with a known reference point to provide a precise location map of the Yankee dryers thermal properties. This allows the engineer to identify various components of the condensate removal system and diagnose any issues which may exist. These may need correction during a planned maintenance shut, or settings may be adjusted during the audit. Along with a review of other critical dryer key performance indicators, tests may be made with dryer variables, such as blowthrough velocity and differential pressure in order to optimize the thermal profile.
