Paper is hygroscopic. Although its typical absolute moisture content ranges from 4-6% of its weight, it can absorb more. Most types of paper are stored at 45-55% RH and approximately 22°C (72°F) to preserve their characteristics. Proper preheat and reheat of incoming air improves product quality in colder climates where there are dedicated outdoor air systems (DOAS) and make-up air units.

Process heaters offer constant heat provision, participating in work process completion to ensure quality paper that does not curl or expand with high moisture or unstable temperature.

Neptronic can help you select the ideal process heater for your needs with capacities up to 40 kW/sq.ft. and 648°C (1200°F) to match your requirements with minimal installed space. This is available in a fully modulating package for precise, energy-efficient control.

We also offer stainless steel construction with SS316L or Incoloy 840 elements to withstand the most demanding process environments.

Our reliable controllers, thermostats and sensors can help monitor your ambient conditions accurately and avoid temperature fluctuations.
