Roben, Mfg, Inc. is a leading manufacturer of low pressure jacketed vessels, specializing in the design, fabrication, and supply of high-quality vessels that meet precise temperature control requirements. With our expertise and state-of-the-art manufacturing facilities, we deliver reliable and efficient low pressure jacketed vessel solutions for various industries and applications.
What is a Low Pressure Jacketed Vessel? A low pressure jacketed vessel is a container designed with an outer shell or jacket surrounding the main vessel. The space between the inner vessel and the outer jacket allows for the circulation of heating or cooling media, enabling precise temperature control of the contents. These vessels typically operate at pressures not exceeding 15 psig (1 bar gauge) in the main chamber.
We utilize advanced thermal modeling software to optimize jacket designs and ensure efficient heat transfer performance.
1. What types of heating/cooling media can be used in jacketed vessels?
Common media include water, steam, glycol solutions, thermal oils, and sometimes refrigerants. The choice depends on the required temperature range and process specifications.
2. How do dimpled jackets differ from conventional jackets?
Dimpled jackets provide increased surface area for heat transfer and promote turbulent flow of the heating/cooling media, often resulting in improved heat transfer efficiency.
3. Can low pressure jacketed vessels be used for both heating and cooling in the same process?
Yes, many jacketed vessels are designed to accommodate both heating and cooling media, allowing for flexible temperature control throughout different process stages.
4. What is the advantage of a multi-zone jacket design?
Multi-zone jackets allow for different temperatures in various sections of the vessel, providing more precise control over temperature gradients or accommodating different process requirements in a single vessel.
5. How is the jacket pressure managed in relation to the main vessel pressure?
Jacket pressure is typically managed independently of the main vessel pressure, with appropriate safety measures such as pressure relief valves to prevent over-pressurization.
6. Can agitation systems be incorporated into low pressure jacketed vessels?
Yes, many jacketed vessels include agitation systems to enhance mixing and heat transfer. The agitator design must consider the presence of the jacket in its configuration.
7. What are the maintenance requirements for low pressure jacketed vessels?
Maintenance typically includes regular inspection of jacket integrity, checking for leaks, ensuring proper functioning of temperature control systems, and cleaning of heat transfer surfaces to maintain efficiency.
8. How is uniform temperature distribution ensured in a jacketed vessel?
Uniform temperature distribution is achieved through proper jacket design, optimized flow patterns of the heating/cooling media, and often the use of agitation within the main vessel.
9. Are there special considerations for CIP/SIP processes in jacketed vessels?
Yes, CIP/SIP systems for jacketed vessels must be designed to clean both the interior of the vessel and the jacket space. Special spray devices and flow patterns may be necessary to ensure thorough cleaning.
10. How do you choose between a conventional jacket and a half-pipe coil jacket?
The choice depends on factors such as required heat transfer rate, cleanability requirements, and cost considerations. Half-pipe coils can offer advantages in terms of pressure ratings and ease of maintenance in some applications.
