Specifications that decide fit
- Material (304 or 316L stainless steel) and internal surface finish, which matter for cleanability and product compatibility.
- Working volume, and the vessel and jacket pressure ratings for heating with steam or cooling with glycol.
- Agitation: anchor, scraped-surface or twin-motion agitators for viscous products, propeller mixers for thin liquids.
- Connections, outlet valve, CIP spray devices and whether the vessel is insulated.
Condition checks
- Interior surfaces and welds free of pitting, dents or discolouration.
- Jacket tested for leaks; insulation dry and intact.
- Agitator drive, seals and scraper blades in good order.
Documents to ask for
Ask for the nameplate data, jacket and vessel pressure ratings, material certificates and drawings. For pressure-rated jackets, check the certification required in your country.
Questions buyers ask
Is 304 stainless steel good enough, or do I need 316L?
304 is fine for many foods and non-corrosive products. Choose 316L for chlorides, acidic products and most pharmaceutical applications.
What does a twin-motion kettle do?
It combines a slow scraper agitator that keeps product moving off the heated wall with a counter-rotating mixer, which suits thick, heat-sensitive products such as sauces and creams.
Can a used tank be modified?
Nozzles, legs and agitators can usually be added or changed by a qualified fabricator; changes to a pressure-rated vessel or jacket require recertification.
