Papermaking Chillers & Temperature Control Units

From pulp preparation to finishing, precise temperature control is a critical focus for papermaking manufacturers to maintain process stability. Our industrial chillers are built to keep these conditions just right, safeguarding equipment and supporting environmental compliance with reliable performance at every stage.

Optimizing Core Processes

Pulp production temperature control: Maintaining water temperatures between 20-40°C helps minimize toxic gas emissions and creates a safer working environment.
Bleaching and cooking efficiency: By keeping process temperatures within the 50-70°C range through efficient heat exchange, our chillers preserve chemical activity, improve bleaching and pulping efficiency, and reduce chlorine consumption.

Protecting Critical Equipment

Steam condensation cooling: Supplying 10-15°C cooling water accelerates steam condensation and recovery, reducing energy loss.
Laser processing support: In cutting applications, our chillers deliver 20 ± 0.5°C cooling water to the laser head, ensuring precise cuts and preventing paper charring caused by heat buildup.

Environmental & Energy-Saving Benefits

Waste heat recovery: Our screw chillers capture waste heat from cooking stages and reuse it to preheat clean water via plate heat exchangers, reducing overall energy consumption by up to 30%.
Wastewater treatment cooling: In wastewater treatment systems, chillers maintain bioreactor temperatures between 30-35°C, preserving microbial activity and improving COD removal efficiency.

Our papermaking chillers deliver value by enhancing process safety through reduced harmful gas emissions, ensuring equipment stability with corrosion resistance and precision control, and promoting sustainability via waste heat recovery, as detailed in the previous sections.

For the best results, we recommend models with modular designs, corrosion-resistant materials, and intelligent temperature control systems, tailored to the specific pH and chlorine content of the pulp.
