New multi-strand copper heating element has greatly increased hose quality:

• Provides 10-times* the flex life compared to previous flat copper heating element
• Long-term, even heating without hot spots
• Backwards compatible with existing Reactor heated hoses

Copper-heated hoses are designed specifically for use with Graco proportioners Covered with proprietary butyl cover for protection against moisture sensitive isocyanate Hoses are covered with foam insulation for heat retention Different fitting sizes on the isocyanate and resin hoses prevent accidentally connecting the wrong hoses together Hoses use custom designed splice kit to electrically connect hoses without having to run copper under the fittings Helix-design whip hose uses braided copper wires for added flexibility and longer life

Resistance Temperature Detector (RTD)

• Graco’s latest advanced controls on Reactor 2 and Integrated Reactor utilize RTD technology. RTDs offer the highest accuracy and the best day-to-day repeatability of material temperatures in your hose. RTD technology allows the machine to automatically shut down if the sensor is damaged, which saves wasted time and materials.
