  • Thermiculite 815 Sheet

    Thermiculite 815 Sheet

    High temperature sheet reinforced with a 0.004˝, 316L stainless steel tanged core. Provides total freedom from oxidation. Chemical compatibility exceeds graphite. Fire safe with proven global track record.

    • Max Temperature: 1800°F (982°C)
    • Max Pressure: 2900 psig (200 bar) (Class 150–300)
    • ASME m: 2.0
    • ASME y: 2500 psi (17 MPa)
  • Change Gasket Brochure

    Change Gasket Brochure

    Incredibly robust and resilient, metal-wound Change heat exchanger gasket is designed to deliver the most dynamic seal ever. Manufactured with proprietary equipment, using a 5-times thicker metal spiral and a unique laser welding process that penetrates completely through. So it requires no inner or outer ring, and is as easy to handle and install as a double-jacketed gasket. Best of all, it’s proven to perform without fail at least 60% longer than any other heat exchanger gasket. Spiral wound. Double jacketed. CMG. Or Kammprofile. And that’s a game changer.

    • Laser welded for higher unit adhesion, pin point accuracy and solid unit construction
    • Available with a locating ring in all sizes - upon request
    • The high level of stored energy gives the Change gasket extremely high recovery
