Custom Insulated Heat Exchangers

Roben, Mfg, Inc. is a leading manufacturer of custom insulated heat exchangers, delivering high-performance thermal transfer equipment for industrial processing applications. Our custom insulated heat exchangers combine efficient heat transfer with superior thermal management, reducing heat loss to the environment and improving overall system efficiency.

What is a Custom Insulated Heat Exchangers?

A custom insulated heat exchanger is a specialized thermal transfer device designed to efficiently exchange heat between two or more fluids while maintaining thermal efficiency through integrated insulation systems. These exchangers incorporate optimized tube arrangements, baffle configurations, and flow patterns to maximize heat transfer coefficients while minimizing pressure drop.

Insulation is critical for heat exchangers operating at extreme temperatures, where heat loss to the environment reduces thermal efficiency and increases operating costs. Our custom insulated heat exchangers deliver reliable thermal performance across applications from cryogenic service to high-temperature process heating.

Why are Custom Insulated Heat Exchangers Needed?

Custom Insulated Heat Exchangers are essential for operations that require:

• Thermal Efficiency: Uninsulated heat exchangers lose significant heat to the environment, reducing effectiveness and increasing utility consumption. Insulation maintains thermal efficiency.
• Temperature Maintenance: Many processes require heat exchangers to deliver fluids at precise temperatures. Insulation prevents temperature loss between the exchanger and downstream equipment.
• Personnel Protection: Hot heat exchanger surfaces pose burn hazards. Insulation protects operators and maintenance personnel from thermal injuries.
• Condensation Prevention: For cold service applications, insulation prevents external condensation that can cause corrosion, ice formation, and structural damage.
• Energy Conservation: Insulated exchangers reduce steam, fuel, or electricity consumption for heating applications, significantly lowering operating costs.
• Process Control: Stable thermal conditions enable precise process control and consistent product quality.
