Custom Insulated Accumulators

Roben Mfg, Inc. is a leading manufacturer of custom insulated accumulators, delivering precision-engineered vessels for surge protection, reflux service, and process buffering applications. Our insulated accumulators maintain stable temperatures for temperature-sensitive fluids while providing the capacity required for smooth, continuous process operations.

What Is a Custom Insulated Accumulator?

A custom insulated accumulator is a pressure vessel designed to provide surge capacity, buffer volume, or intermediate storage in process systems while maintaining controlled temperatures through integrated insulation. These vessels dampen flow variations, provide residence time for phase separation, and ensure steady feed rates to downstream equipment.

Insulation is essential for accumulators handling fluids requiring strict temperature control, whether to prevent solidification, maintain phase stability, or preserve product quality. Our custom insulated accumulators deliver reliable thermal management across diverse industrial applications.

Why Are Custom Insulated Accumulators Needed?

Custom insulated accumulators are essential for operations that require:

• Temperature-Sensitive Storage: Many fluids require temperature maintenance to prevent solidification, phase changes, or degradation.
• Heat Loss Prevention: Insulation minimizes heat loss, reducing reheating requirements and energy consumption.
• Condensation Control: Insulation prevents condensation and ice formation in cold service applications.
• Product Quality: Stable temperatures preserve product integrity during residence time.
• Personnel Safety: Insulated surfaces reduce burn hazards.
• Energy Efficiency: Reduced heat loss supports energy conservation and lowers operating costs.
