Polyurethane Insulated Heat Exchangers

A polyurethane insulated heat exchanger is a thermal transfer device with integrated polyurethane foam insulation that maximizes heat transfer efficiency between process fluids while minimizing heat loss to the environment. These exchangers combine optimized tube arrangements with superior insulation to deliver reliable thermal performance and reduced operating costs.

Why are Polyurethane Insulated Heat Exchangers Needed?

Polyurethane insulated heat exchangers are essential for applications where heat loss to the environment reduces thermal efficiency and increases operating costs. The exceptional thermal resistance of polyurethane insulation maintains designed temperature differentials, improves heat recovery, and protects personnel from hot surfaces.

Polyurethane Insulated Heat Exchangers Applications

Common applications include:

• Process heating and cooling
• Heat recovery systems

Polyurethane Insulated Heat Exchangers Frequently Asked Questions (FAQs)

How much energy can polyurethane insulation save on heat exchangers?

Energy savings depend on operating temperatures, ambient conditions, and insulation thickness. Typical savings range from 80-95% reduction in heat loss compared to uninsulated exchangers. Our engineering team can provide specific calculations for your application to quantify expected energy savings and payback period.

What TEMA classes do you manufacture for insulated heat exchangers?

We manufacture heat exchangers to all TEMA classes including Class R (refinery and heavy-duty service), Class C (chemical service), and Class B (general service). The polyurethane insulation system is compatible with all TEMA configurations and can be applied to both shop-fabricated and field-erected exchangers.

Can polyurethane insulation be applied to existing heat exchangers?

Yes, spray-applied polyurethane foam is an excellent retrofit solution for existing heat exchangers. The foam conforms to complex geometries including shells, heads, and nozzles, providing continuous insulation coverage. Professional installation includes surface preparation, foam application, and weather-resistant jacketing.
