Product catalog summary
Overview of Equatherm® Rolls
Equatherm® Rolls by Nordson XALOY are designed for optimal performance in double shell spiral heat-transfer applications. These rolls feature a patented construction where water flows through a stainless steel spiral with a PTFE gasket, creating a sealed flow path between the inner and outer shell. The spiral size and pitch are optimized to meet specific heat-transfer requirements.

Benefits
  • Maximum Heat-Transfer Rate: Enhances productivity by allowing specification of rolls for maximum line speed or minimum roll size.
  • Energy Savings: The efficient spiral design reduces costs associated with heating, cooling, and pumping process water.
  • Improved Product Quality: Ensures uniform temperature across the roll face, minimizing variations in gauge and appearance.

Quality Assurance
  • Computerized heat transfer and mechanical analysis for various applications including cast film, extrusion coating, and more.
  • ASME Code Certified for manufacturing and repairing rolls with "U" and "R" Stamp Approval.
  • Hard chrome plating with 63-65 Rc hardness.
  • Acid flushing and flow testing capabilities up to 10 tons and 500 GPM maximum.

Roll Repair and Refinishing Services
  • Complete repair and remanufacturing services for chill rolls used in sheet, film paper coating, and heat transfer applications.
  • Specializes in regular maintenance and modified finish requirements, offering in-house chrome plating and finishing.
  • Capabilities include handling rolls up to 42” (1065 mm) in diameter and 210” (5330 mm) in length.
  • Precision finishing facility provides 0.0005” (13 mm) TIR on every order.

Special Finishing Services
  • Offers a range of finishes from flawless mirror to coarse matte.
  • Specialty finishes include water retention, flash plating over matte, pocket release, 30-50% gloss, and tungsten carbide coating.
