HCS3100 – RepairClave

HCS3100 – RepairClave

The HCS3100 RepairClave is a semi-portable pressure vessel designed to provide controlled temperature, vacuum, and pressure during composite and metal bond repair processes.

RepairClaves are custom built with standard vessel lengths starting at 3ft up to 30ft (progressing in 3ft increments).

United States Patent and Canadian Patent Technology

RepairClaves are custom built with optimized interior space and internal connectors for easy use. When in operation, positive internal pressure is applied to the composite repair to achieve the higher pressure when required.

The RepairClave is ideal for repair applications that include helicopter blades, thrust reversers, cowling, flaps, or ailerons.

Feature Include:

  • Localized heat
  • Controlled temperature
  • Vacuum and pressure functionality
  • Heatcon hot bonder technology
  • Removable part carrier
  • Lighted interior
  • Adjustable operating pressure
  • Flanged access ports
