Custom & OEM Heat Exchanger Manufacturer: A Complete Guide

Reading time: 7 min read

As an experienced custom and OEM heat exchanger manufacturer based in China, Shanghai Jiangxing provides tailored thermal solutions designed to meet your specific application requirements, from initial collaborative design to full-scale production and export.

01

What Is a Custom or OEM Heat Exchanger?

A custom heat exchanger is a unit uniquely designed by a manufacturer like Shanghai Jiangxing to meet the specific thermal, physical, and material requirements of a customer's process. OEM (Original Equipment Manufacturer) production involves us manufacturing heat exchangers for another company to integrate into their larger product or system, often under their brand name. We offer both services, providing engineering expertise for one-off projects and reliable, scalable production for OEM partners.

02

How does the custom heat exchanger design process work?

Our custom design process is collaborative and engineering-led. It begins with an initial consultation to understand your needs, led by our contact Blair. We then perform thermal modeling to determine the required size and plate configuration, followed by CAD drawings for your approval, material selection (e.g., 316L, Titanium) and fabrication and pressure testing at our Shanghai facility. The final unit is verified against approved process data and agreed acceptance criteria.

03

What information is needed to design a custom heat exchanger?

To begin the design process for a custom unit, our engineers require key technical data. This includes the types of fluids involved, their flow rates, inlet and outlet temperatures, operating pressures, and any physical space or connection constraints. The more detailed the information you provide, the more accurately we can model and design the ideal thermal solution for your application. We can work with you to define these parameters if they are not fully known.

04

Why choose Shanghai Jiangxing for OEM manufacturing?

For OEM partners, Shanghai Jiangxing offers an engineering-led manufacturing solution. Our location in Shanghai, China provides access to a robust supply chain for plate alloys and components. We maintain strict confidentiality and quality control, with capabilities to manufacture according to ASME, PED and other international codes where the code route is specified and confirmed in writing for the order. Shipping plan and delivery schedule are confirmed per order. To discuss a partnership, contact Blair at blair@shheatex.com.

05

What types of heat exchangers can be customized?

We can customize our full range of products, including gasketed plate heat exchangers, fully-welded units, brazed plate models, and shell-and-tube exchangers. Customizations can range from unique connection sizes and locations to non-standard materials for plates or shells, and specific design pressures or temperatures to handle challenging industrial processes. Our engineering team is adept at finding solutions for unique requirements.

Frequently asked questions

What is the typical lead time for a custom heat exchanger?

Lead time for a custom heat exchanger is quoted and confirmed per design, material, quantity and current production schedule, and also depends on design complexity and the certification route requested. Once the design is approved, a firm manufacturing and delivery schedule is issued for your project planning.

Is there a Minimum Order Quantity (MOQ) for custom or OEM orders?

Minimum order quantity is confirmed at quotation and depends on the design, materials and production route. We handle both one-off custom units and repeat OEM production; tell us the design and annual volume you have in mind and we will confirm what is workable.

Can you provide designs that comply with specific industry standards?

Yes. Our engineering team designs heat exchangers against international standards such as ASME Section VIII, the European Pressure Equipment Directive (PED) and GB codes. The code route, third-party inspection scope and the documentation set issued with the unit are specified in the enquiry and confirmed in writing for the order.

How do I start a custom or OEM project with you?

To start a project, please contact Blair at blair@shheatex.com or on WhatsApp at +86 133 1175 6331. He will coordinate with our engineering team to review your requirements and begin the initial design and quotation process. We look forward to collaborating on your project.
