Conventional Jacket Systems
Roben, Mfg, Inc. is a leading manufacturer of conventional jacket systems, specializing in the design, engineering, and fabrication of traditional jacketed pressure vessels that provide reliable, cost-effective heat transfer for a wide range of industrial processing applications. Our conventional jacket systems deliver proven thermal performance through time-tested designs that offer excellent durability, straightforward maintenance, and broad compatibility with heating and cooling media for chemical processing, pharmaceutical manufacturing, and food production operations.
What Are Conventional Jacket Systems?
A conventional jacket system is a heat exchange vessel configuration featuring an outer shell (jacket) that completely surrounds the inner process vessel, creating an annular space through which heating or cooling media flows to transfer thermal energy to or from the vessel contents. This traditional double-wall construction provides uniform heat distribution across the entire vessel surface, with media entering through inlet nozzles and exiting through outlet connections positioned to ensure complete jacket coverage. Conventional jackets accommodate steam, hot water, thermal fluids, glycol solutions, and refrigerants as heat transfer media, making them versatile solutions for applications requiring temperatures from -40°C to 350°C.
Why Choose Conventional Jacket Systems?
Conventional Jacket Systems offer several critical advantages for thermal processing:
- Proven Reliability: Time-tested design with decades of successful industrial application and well-understood performance characteristics
- Uniform Heat Distribution: Full vessel coverage provides consistent temperature profiles across the entire heat transfer surface
- Media Flexibility: Compatible with steam, water, thermal fluids, glycol, and refrigerants for heating and cooling applications
- Simple Maintenance: Straightforward construction allows easy inspection, cleaning, and repair of jacket components
- Cost-Effective Design: Lower fabrication complexity compared to enhanced jacket types reduces initial capital investment

Frequently Asked Questions About Conventional Jacket Systems
What heat transfer media can be used in conventional jacket systems?
Conventional jacket systems accommodate a wide range of heat transfer media including saturated and superheated steam, hot water, thermal oils (Dowtherm, Therminol), glycol-water solutions, chilled water, and refrigerants. Media selection depends on required temperature range, heat transfer rates, and process compatibility.
How is heat transfer efficiency optimized in conventional jacket systems?
Heat transfer efficiency is optimized through proper jacket gap sizing, spiral baffles that promote turbulent media flow, strategic inlet/outlet placement, and adequate media flow rates. Internal agitation of vessel contents further enhances overall heat transfer coefficients.
What pressure ratings are available for conventional jacket systems?
Roben Mfg fabricates conventional jacket systems with jacket-side pressure ratings from 15 PSIG for low-pressure hot water applications to 300 PSIG for high-pressure steam service. Inner vessel pressure ratings are independently specified based on process requirements.
