Chemical Blending Skid System

This fast-paced, eight station, 130′ skid project was designed, built, procured, tested, and installed to meet the drastic demand for pool chemicals during the COVID-19 pandemic. Two blending systems for dry chemical powders are fed directly into bulk bags or totes for operator safety and product dust control. A hoist system is used to drop main and minor ingredients directly into two large horizontal paddle mixers, and an integrated dust collection system discharges back into the blender for product recovery.



  • Four minor ingredient stations allow for accurate dosing of ingredients to create consistent blends. Two hand-add stations are equipped with dust collection for operator safety.
  • Increased batch capacity by 40%.
  • System can be monitored remotely increasing quality control, accuracy, and efficiency.
