New & Used Processing Vessels For Sale

What is an industrial processing vessel?

An industrial processing vessel is a tank designed for use in chemical, pharmaceutical, food, biotech and water treatment processing. Processing vessels typically include features such as jacketed walls for heating or cooling, agitator mountings, dish or torispherical heads, sanitary fittings, sight glasses, instrumentation nozzles and CIP/SIP capability. They differ from simple storage tanks in being engineered for active processing rather than static holding. Industrial processing vessels are typically specified by working volume, design pressure, design temperature, materials of construction, jacket type and certification (PED/UKCA, ASME, GMP, 3A, EHEDG, FDA).

How long do processing vessels last?

Quality industrial processing vessels routinely operate for 30-50+ years, often outliving multiple changes of ownership. The pressure-containing structure typically lasts the working life of the vessel, with periodic PSSR inspection confirming continued integrity. Internal wear items (mechanical seals, bearings, agitator components) and external services (jackets, instrumentation) may need refurbishment cycles every 5-15 years depending on duty.

Why choose an industrial processing vessel?

Processing vessels are the heart of most batch processing plant, providing the controlled environment where reactions, mixing, dissolution and product formation happen.

• Controlled processing environment: jacketed walls, agitation, instrumentation and pressure rating provide the controlled environment needed for product quality and process repeatability.
• Materials and certification: 316L stainless, duplex, glass-lined and specialist alloy options support every chemical and product compatibility requirement.
• Hygiene options for food and pharma: sanitary design with electropolished surfaces, drainable construction and CIP/SIP capability supports GMP, HACCP and product safety.
• Pressure capability: vessels rated from atmospheric up to 50+ bar support virtually every process duty, with PED/UKCA certification confirming compliance.
• Long working life: the robust construction and high-quality materials used in processing vessels deliver decades of service, making them excellent capital investments.

Why buy a used processing vessel?

Processing vessels are exceptional candidates for second-hand purchase because the pressure-containing structure lasts decades.

• Major capital savings: used processing vessels typically cost 40-70% less than new equivalents, particularly on large or alloy-construction vessels.
• Immediate availability: new vessels in alloy materials can have lead times of 8-15 months. Used stock is often available within weeks.
• Refurbishment-friendly: internal repolishing, jacket repair, mechanical seal renewal and instrumentation upgrades return used vessels to as-new condition.
• Documented certification: vessels with current PED/UKCA certification, last hydrotest results and PSSR inspection records give clear evidence of integrity.
• Strong UK aftermarket: vessel refurbishment specialists offer full repolishing, certification, jacket repair and modification services.

Types of industrial processing vessels for sale

Jacketed batch vessels

Single-jacket, double-jacket and limpet-coil vessels with capacity for heating or cooling during processing. Standard for chemical batch processing, formulation, dissolution and crystallisation. Capacities range from sub-50L pilot vessels up to 50,000L+ production vessels.

Sanitary mix tanks

3A, EHEDG and FDA-aligned sanitary vessels with electropolished interior, drainable construction, sanitary fittings and CIP/SIP capability. Standard for food, dairy, beverage, pharmaceutical and biotech batch processing. 316L stainless construction is typical.

Pressure-rated processing vessels

PED/UKCA-certified pressure vessels (typically rated from 1 bar up to 50+ bar) for pharmaceutical, biotech, chemical and specialty production. ASME Section VIII certification is also common on imported vessels. PSSR-compliant maintenance and inspection regimes apply.

Glass-lined and specialty alloy vessels

Glass-lined steel vessels (Pfaudler, De Dietrich) handle aggressive chemicals including strong acids and chlorinated organics. Specialty alloys (Hastelloy, Inconel, Monel, titanium, duplex/super-duplex) serve corrosive, high-temperature or specialty duties.

Atmospheric process tanks

Open-top and closed atmospheric tanks for bulk liquid processing, water treatment, dissolution, holding and mixing duties where pressure rating isn’t needed. Stainless steel, GRP and lined carbon steel constructions all serve different duty requirements.

Specialty processing vessels

Cone-bottom drain vessels, dimpled jacket cooling tanks, agitated nutsche filter dryers, vacuum vessels and specialty geometry processing tanks for specific batch processing applications.

Key features to consider when buying a processing vessel

• Working volume vs total volume: specify operating volume rather than total. Typical fill is 70-85% to allow for agitation, foaming and reaction expansion.
• Materials of construction: 316L stainless for most food/pharma/chemical duty; duplex/super-duplex for chlorides and seawater; glass-lined for strong acids; Hastelloy/titanium for severe corrosion.
• Design pressure and temperature: must envelope your operating conditions. PED/UKCA certification confirms compliance. PSSR inspection regime applies in service.
• Jacket type: full jacket for high heat transfer; limpet coils for steam; dimpled jackets for lower-pressure water; verify jacket pressure rating against utility specification.
• Surface finish: Ra 0.4-0.8 micron electropolished for pharma; Ra 0.8-1.6 brushed/polished for food; mill finish acceptable for chemical duty.
• Agitator and seal: mechanical seals (single, double, gas-barrier) need verification against your duty. Seal flush systems and seal water support add complexity.
• Hygiene and certification: 3A, EHEDG, FDA, GMP requirements depend on application. Sanitary fittings, drainable design and validation documentation must match the certification level.
• ATEX rating: essential for solvents, flammable products or explosive atmospheres. Always verify current certification on used vessels.

Industries and use cases for processing vessels

• Chemical and petrochemical: batch reactions, blending, formulation, dissolution, crystallisation and intermediate processing.
• Pharmaceutical and biotech: API processing, formulation, fermentation, crystallisation, sterile holding and batch manufacturing.
• Food and beverage: syrup mixing, dairy processing, brewing wort handling, juice processing and sanitary batch preparation.
• Cosmetics and personal care: cream, lotion, shampoo, gel and pharmaceutical-grade cosmetic formulation.
• Water and wastewater: chemical dosing, holding, mixing and treatment processes.
• Specialty chemicals: fine chemical processing, specialty intermediate manufacture and high-value batch production.

What locations do we serve for processing vessels?

As a buyer-to-seller marketplace, we feature processing vessels from sellers across the UK and beyond. Use our location and distance filters to find equipment near your facility, supporting site visits and reducing transport costs on large vessel installations.

Can I return a processing vessel?

As we operate as a buyer-to-seller marketplace, any returns policy must be agreed directly with the seller before purchase. We’d recommend pre-purchase inspection of any used processing vessel, including review of pressure test certificates, PSSR inspection records, internal surface condition and any thickness measurement reports.
