For Reactor proportioners.

• 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.
