Food & Beverage: Ingredient storage, blending, fermentation, and sanitary processing
Pharmaceutical & Biotech: Controlled storage and mixing of sensitive materials
Oil & Gas / Energy: Fuel storage, chemical containment, and process support
Water & Wastewater Treatment: Holding, treatment, and sludge processing
Used Tanks Buying Considerations
When selecting a used tank, it is important to evaluate both process requirements and equipment condition:
Capacity & Volume: Ensure the tank size aligns with production throughput and storage needs
Material of Construction: Match tank material (stainless, carbon steel, plastic) to process chemistry
Pressure & Temperature Ratings: Confirm compatibility with operating conditions
Configuration & Features: Evaluate agitation, insulation, jackets, and fittings
Condition & Inspection History: Review prior use, maintenance records, and structural integrity
Why Buy Used Tanks
Buying used tanks provides a cost-effective solution for expanding storage or processing capacity without the long lead times associated with new equipment.

A tank is an industrial vessel used to store, process, or transport liquids, gases, or bulk materials. Tanks are designed in various sizes and materials depending on the application and may include features such as agitation, insulation, or pressure ratings for specific process requirements.
Used tanks are available in stainless steel, carbon steel, plastic, and fiberglass constructions, with sizes ranging from small batch vessels to large bulk storage tanks. Configurations may include jacketed tanks, mixing tanks, pressure vessels, and insulated storage tanks for different industrial processes.
Choosing the right tank depends on material compatibility, required capacity, operating pressure and temperature, and process needs such as mixing or heating. Evaluating tank construction, fittings, and previous usage helps ensure the equipment aligns with your production requirements.
The cost of a used tank varies based on size, material of construction, condition, and features such as agitation or pressure rating. Larger stainless steel tanks or specialized vessels typically command higher prices. Contacting a sales representative can help determine current availability and pricing.
