ITW Ransburg has introduced the AquaBlock 2 voltage isolation system for waterborne systems. The AquaBlock 2 is designed to “block” high-voltage electrostatic paint applicators from a grounded waterborne coating supply. By combining the advantages of waterborne coating technology with the efficiency of electrostatics, the product is said to reduce both a company’s environmental impact and operating expenses. It can fit into any paint feed system with single or multiple applicators. Pneumatic controls simplify the operation for higher productivity and less need for troubleshooting, and quick color change minimizes interruptions and delays.
