Significant reduction in water usage leads to a substantial decrease in water bills! Rotary asphalt extraction device.

The "ACE-II NA-900" is an asphalt extraction device that incorporates a system for circulating cooling water internally and a system for cooling the collected water using a refrigeration unit, built into a conventional centrifugal extraction apparatus. This device extracts and recovers asphalt components by injecting solvent into a sample container containing asphalt mixture while rotating at high speed, allowing the solvent to dissolve the asphalt components. The recovered extraction solvent is distilled and regenerated for reuse in asphalt extraction. This method significantly reduces extraction time compared to a Soxhlet apparatus. Additionally, the amount of cooling water used is drastically reduced, leading to substantial savings on water bills. 【Features】 ■ Fully automatic extraction testing process ■ Equipped with a refrigeration unit and a pump-mounted water tank ■ Significant cost reduction in tap water usage ■ Improved solvent recovery rate through temperature settings of cooling water *For more details, please refer to the PDF document or feel free to contact us.
