Used Industrial Autoclaves
& Steam Sterilizers

Used Industrial Autoclaves & Sterilizers — What We Source

SIGMA Process Equipment trades in used industrial autoclaves for sale and used steam sterilizers sourced from decommissioned pharmaceutical, food processing, composite manufacturing, and chemical facilities. Because this is a specialist category with low turnover, we maintain a sourcing-on-request model rather than a large standing stock. Used autoclave for sale enquiries are matched against our network within 24 hours.

Industrial Steam Autoclaves

A used industrial steam autoclave runs saturated steam cycles — typically 121°C at 1 bar(g) or 134°C at 2 bar(g) — for sterilisation of pharmaceutical products, medical devices, and laboratory materials at industrial scale. Unlike dental or benchtop units, industrial steam autoclaves range from several hundred litres to multiple cubic metres of chamber volume, with full PLC control and automated cycle validation. We source used steam autoclaves and pre-owned autoclaves from plant closures across Europe, Asia, and North America.

Common applications: pharmaceutical batch sterilisation, contract sterilisation services, medical device manufacturing, waste treatment autoclaving. Autoclaving equipment in this category is assessed for pressure vessel certification, steam trap and jacket condition, door seal integrity, and control system status.

Composite Autoclaves

A used composite autoclave for sale is a high-pressure vessel — typically operating at 5–10 bar(g) and 175–200°C — used to cure prepreg fibre-reinforced composites (carbon fibre, glass fibre) under controlled pressure and temperature. These are primarily aerospace and advanced materials equipment. Composite autoclaves are high-value, infrequently traded units; we source them from aerospace MRO facilities and composite manufacturing closures on request.

Retort Systems

An industrial retort is a pressure steriliser designed specifically for pressurised steam sterilization of sealed food containers — cans, pouches, and trays — at temperatures above 100°C. Used retort machines appear on the market when canneries and food processors upgrade to continuous retort lines. Both batch retorts (vertical and horizontal) and rotary retort types are occasionally available. These overlap with food processing equipment; see also food processing equipment.

Mushroom Cultivation Autoclaves

Specialist autoclave for mushroom cultivation and autoclave for mushroom spawn production are smaller industrial units — typically 200–2,000 L — used to sterilise grain, sawdust, or straw substrate before inoculation. These units see frequent trade as mushroom farms scale up. If you need a mushroom autoclave for sale, include substrate volume and batch cycle time in your enquiry.

Hydrogen Peroxide Sterilizers

Hydrogen peroxide sterilizers (vaporised H₂O₂ systems) provide low-temperature sterilisation for heat-sensitive devices and cleanrooms. Used VHP sterilisers from major manufacturers are occasionally available. Contact us with your room volume or load configuration.

Autoclave Energy & Operational Considerations

When evaluating a second hand autoclave for sale, key operational parameters include: chamber volume (L), maximum working pressure (bar), maximum temperature (°C), steam supply requirement (kg/h), cycle controller type (PLC/SCADA compatibility), and door configuration (single-end or pass-through). We can provide available specification sheets and condition photographs with every enquiry.

• Pressure vessel certification — ask for the current pressure vessel inspection certificate (PED, ASME, or local equivalent).
• Steam consumption — autoclave energy consumption scales with chamber volume and cycle frequency; confirm steam supply capacity before committing.
• Autoclave dry heat sterilization vs steam — dry heat autoclaves (pulsed air ovens) are a separate category used for glassware and anhydrous materials; specify which type you need.
• Autoclave machine types — gravity displacement, pre-vacuum (B-type), and flash autoclave cycles; confirm which cycle type is validated for your load.
