The HSS Sterilizer Refurbishing Process

All equipment is fully refurbished at the HSS facility in Oregon by experienced, licensed technicians following a three-step process.

Step 1 STEP 1: Receive, qualify, strip, and clean all components and controls.

  • Inspect American Society of Mechanical Engineers (ASME) boiler plate stamps and numbers to qualify the chamber for its intended use.
  • Disassemble door, remove chamber from frame, strip chamber’s insulating blanket.
  • Clean chamber, stand, and door individually with glass beads under high pressure. This effectively removes rust, grime, and residue and provides a smoother, stronger finish than sandblasting.


Step 2 STEP 2: Testing, painting, and reassembly.

  • Subject cleaned chamber to hydro-static testing as required by law to certify its integrity as a pressure chamber.
  • Paint the outer chamber, stand, and brackets with a rust-inhibiting sealant and final finish coat.
  • Resurface all stainless panels.
  • Install a new insulating blanket.
  • Attach chamber to the finished stand.
  • Reassemble door, replacing worn or out of tolerance parts with new ones.
  • Remount door to chamber.


Step 3 STEP 3: Plumbing, electrical wiring, and final testing.

  • Attach control assemblies.
  • Install plumbing components and wiring harnesses.
  • Make electrical connections.
  • Test each phase and function to ensure trouble-free operation.
  • Validate the operation of the sterilizer using in-chamber pressure and temperature data loggers.
  • Prep, palletize, and crate the unit for shipping.
