TRUMARK continues the Wellons tradition of providing the best lumber dry kiln technology. Designed and fabricated in-house, key features include:

  • Accurate moisture content measurement above and below fiber saturation.

  • Integration with Wellons WINKILN control software.

  • Automatic kiln shutdown when final moisture content is reached.

  • Full utilization of CMZ exit air control benefits, with multiple sensor configurations available.




TRUMARK has the unique ability to accurately determine moisture content of the sampled lumber both above and below fiber saturation. The transition through fiber saturation is known to be a critical stage of the drying schedule, but until now knowing when this is occurring has been by conjecture alone. With TRUMARK, schedule development and refinement is both easier and more precise.


Multiple sensor assembly configurations are available to accommodate any kiln length. Sensor assemblies consist of two plates 48" long, placed approximately 15 courses apart, a sensor panel located either on the roof or on the side of the kiln, clip bracket, two (2) clips and attached wiring. This arrangement provides greater sampling range and accuracy than previously available.


The system provides automatic kiln shutdown based on actual moisture content versus time and is accurate to near 1%. In addition, operator decisions such as when to initialize equalizing or conditioning can now be based upon actual moisture content readings, instead of time alone.


TRUMARK easily ties in with both new and existing Wellons CMZ dry kiln control systems, and works in conjunction with TDAL to provide better control of the drying process than ever before.
