Shell and Tube Heat Exchanger Manufacturer and Supplier in UAE
United Heat Exchangers is an India-based shell and tube heat exchanger manufacturer and supplier serving the UAE — designing and fabricating carbon steel, stainless steel, duplex, titanium, and Hastelloy exchangers for refineries, gas plants, desalination trains, and process facilities across all seven emirates.UAE process industries operate in one of the most demanding thermal environments in the world — high ambient design temperatures, seawater-based cooling in coastal facilities, and process streams ranging from sweet crude to sour gas. Every shell and tube heat exchanger we supply to the UAE is engineered against ASME Section VIII, TEMA, and API 660 to perform reliably under these exact site conditions, with a complete documentation package for local regulatory and insurance sign-off.
How a Shell and Tube Heat Exchanger Works
In this configuration. One fluid travels inside a set of tubes, while another fluid surrounds them inside an outer shell. Heat passes between the two fluids through the tube walls, allowing them to exchange temperatures without ever coming into direct contact. Baffles direct shell-side flow for maximum contact with the tube bundle.
Tube-Side Fluid Enters
The cooling or process fluid flows into the inlet channel, where the tubesheet directs it into the individual tubes of the bundle.
Shell-Side Fluid Crosses Bundle
The second fluid flows through the shell, directed by baffles for maximum contact time with the tube surface.
Heat Transfers Through Tube Wall
The tube wall acts as a thermal bridge, allowing heat to flow from the hotter liquid to the cooler one without letting the two fluids physically mix.
Both Streams Exit
Tube-side and shell-side fluids leave at their design outlet temperatures through separate nozzles.
Bundle Removable for Service
U-tube and floating head models allow the entire tube bundle to be removed for maintenance.
Engineering Insight — Designing for UAE Site Conditions: Cooling water in Gulf coastal facilities is drawn from seawater at elevated ambient temperature, reducing the available approach temperature compared with temperate climates. Shell and tube exchangers supplied into the UAE are rated against local seawater supply temperature and dry-bulb design conditions specific to each emirate, not generic international defaults, to guarantee the specified outlet temperature is actually achievable on site.
Types of Shell and Tube Heat Exchangers We Supply
United Heat Exchangers manufactures and supplies the full range of shell and tube configurations used across UAE refining, gas processing, desalination, and marine industry.
Fixed Tubesheet Exchanger
Simplest, most economical constructionBoth tubesheets are welded directly to the shell — the most cost-effective configuration for clean, non-fouling services where the shell side does not require mechanical cleaning.
- Lowest-cost shell and tube configuration
- Standard for clean utility and closed-loop cooling duties
- No provision for differential thermal expansion beyond expansion joint
U-Tube Exchanger
Bundle removable, handles thermal expansionTubes are bent into a U-shape with both ends on a single tubesheet, allowing the bundle to expand independently of the shell and be withdrawn for tube-side cleaning.
- Accommodates high differential temperature between shell and tube side
- Removable bundle for shell-side inspection and cleaning
- Standard for gas compression inter-coolers and process reboilers
Floating Head Exchanger
Full tube-side and shell-side accessOne tubesheet floats independently of the shell, allowing the entire bundle to be removed for cleaning on both the tube side and shell side — the preferred design for fouling services.
- Full mechanical access to both sides for heavy fouling streams
- Standard for crude preheat trains and heavy hydrocarbon services
- TEMA Class R construction for refinery-severity duty
Multi-Pass and Multi-Shell Configurations
Engineered for close temperature approachTwo or more tube passes, or multiple shells in series, correct the mean temperature difference for close-approach duties — common in UAE desalination and gas processing trains.
- Improves thermal effectiveness for close-approach process duties
- Configured to fit constrained plot space on existing skids
- Sized in HTRI Xist for the exact approach temperature specified

Frequently Asked Questions — Shell and Tube Heat Exchanger in the UAE
Do you supply shell and tube heat exchangers directly to UAE project sites?
Yes. United Heat Exchangers ships directly to project sites and free zones across all seven emirates, with sea freight routed to Jebel Ali, Khalifa Port, Port of Fujairah, Saqr Port, or Hamriyah Port depending on the delivery location, and full export documentation prepared in-house.
Which material is recommended for seawater-cooled exchangers in Fujairah or coastal UAE facilities?
Titanium tubes are the standard recommendation for continuous seawater cooling duty in coastal UAE facilities, particularly around Fujairah's bunkering and oil storage terminals, due to their complete immunity to chloride pitting. Duplex stainless steel is a cost-effective alternative where the duty is brackish or intermittent rather than full-strength continuous seawater.
Are your shell and tube heat exchangers designed for UAE ambient and seawater conditions?
Yes. Thermal sizing in HTRI Xist uses the actual design ambient dry-bulb temperature and cooling water supply temperature for the specific emirate and site, not generic international defaults, so the guaranteed outlet temperature is achievable under real Gulf summer conditions.
What documentation is provided for ADNOC or DEWA project approval?
Every exchanger ships with a signed API 660 data sheet, ASME U-1 Manufacturer's Data Report, full material mill certificates, NDE reports, and a third-party inspection release certificate where a TPI agency has been appointed — the standard documentation package accepted for ADNOC, DEWA, SEWA, and EPC contractor project approval.
What is the lead time for a shell and tube heat exchanger shipped to the UAE?
Standard carbon steel or stainless steel units are ready ex-works in 6–10 weeks; alloy or ASME U-Stamp units take 12–20 weeks. Sea freight transit from Indian ports to Jebel Ali or Khalifa Port typically adds 2–3 weeks. Expedited manufacturing is available for plant turnarounds and emergency replacements — contact us with your project timeline.
Can you replicate an existing exchanger for a UAE plant turnaround?
Yes. Send the original fabrication drawing, nameplate data, or the existing unit's dimensions and process datasheet, and we will reverse-engineer a like-for-like or upgraded-material replacement sized and certified for your turnaround schedule.
