We are experts in engineering pressure vessels with integral high-pressure agitation and mixing systems:

Allowing finer control of the temperature gradient throughout the vessel and ensuring the temperature of the DUT remains within a tightly specified tolerance band, throughout the entire test period.

To establish an even distribution of mixed particles within the test media, for chemical mixing, blending or environmental simulation.

To improve heat transfer of the test media by forced convection; reducing time required to heat / cool the media and improving efficiency of heating / cooling system.

Performance & efficiency of the agitation or mixing system design can be proven using Computational Fluid Dynamics (CFD); ensuring temperature or particle distribution satisfies requirements prior to manufacture.

KW Designed Solutions has an extensive catalogue of high-pressure agitation systems on offer, with various types of pressure vessel; each of them bespoke to ensure the customer’s exacting requirements.

Applications & Customer Uses

Pressure vessels with integrated agitation are a common choice with customers who work within the subsea and materials research sectors.

Mixing and stirring applications improve the heating / cooling efficiency within test systems and create an even temperature distribution of test media within the vessel and test platform.

Designed uniquely for customers who manufacture subsea equipment; our agitation system allows the creation of an ideal subsea testing environment. We can create an even distribution of sand and silt throughout the vessel, whilst conducting wet-mate electrical connector testing (mate/ demate functionality). This added functionality has vastly improved the realism of testing platforms; enabling them to meet the most stringent testing requirements and demands.

Our high temperature, NACE compliant agitation systems enhance testing conditions, whilst also operating at high pressure and high temperature in the most hostile and corrosive environments. Including autoclaves supplied to clients in material research laboratories performing ASTM G-38 type Stress Corrosion Cracking (SCC) tests in Sour Gas H2S.
