Power & Energy
HEI-standard condensers, coolers and heat recovery equipment for conventional and renewable generation.
What This Sector
Demands
Dolphin Group is an ADNOC-approved, ICV+ certified manufacturer and service provider of HEI- and ASME Section VIII Div.1-compliant condensers, coolers and heat recovery equipment for power generation. Operating from its Mussafah, Abu Dhabi facility for over 40 years, it delivers retubing and rapid repair capability to gas, steam and solar thermal plants worldwide.
Condenser performance decay
Microfouling and air in-leakage raise back-pressure — every millibar costs megawatts and heat rate. Left to accumulate, the loss compounds quietly until a planned outage becomes the only practical fix.
Forced outage risk
A single cooler failure can trip a unit. Spares strategy and rapid repair capability decide availability figures, since every hour a unit is down for an unplanned cooler failure is an hour of lost generation.
Water chemistry attack
Seawater and treated cooling water corrode copper alloys and carbon steel; material upgrades must be engineered, not guessed. Get the material selection wrong and the same corrosion that drove the last retube starts again on day one.
What We Deliver for
Power & Energy
The specific heat exchange equipment and services we design, fabricate and maintain for this sector.
Shell & Tube Heat Exchangers
Lube oil coolers, closed cooling water exchangers and feedwater heaters.
Plate Heat Exchangers
Closed cooling water and lube oil duty with titanium seawater plates.
Tube Replacement & Retubing
Condenser retubing campaigns — thousands of tubes per outage.
Proven in Power & Energy
Real outcomes from real power & energy projects — not catalogue claims.
Steam plant condenser retubing
2,800 titanium tubes replaced in a planned outage; unit restored to full design capacity.
ADNOC-approved, ICV+ certified
Qualified to the procurement standards ADNOC group companies require, with in-country value that scores directly on generation-sector tenders. Dolphin Group is one of roughly 70 ICV+ certified companies in the UAE, a distinction that separates us from vendors offering price alone.
Rapid repair to protect availability
Forced-outage repair and spares mobilise from Mussafah fast enough to protect unit availability figures when a cooler or condenser fails. Every millibar of back-pressure lost to microfouling and air in-leakage costs megawatts, so response speed translates directly into heat rate protected.

40+ years of condenser and cooler experience
Four decades of HEI-standard retubing and material-upgrade engineering inform every condenser and cooler we build for power generation duty. That experience put 2,800 titanium tubes into a steam plant condenser during a single planned outage, restoring full design capacity.
Frequently Asked Questions
Yes. We design and manufacture to HEI Standards alongside ASME Section VIII Div.1 and TEMA Class C for surface condensers, lube oil coolers and closed cooling water exchangers.
Yes. We replaced 2,800 titanium tubes in a steam plant condenser during a planned outage, restoring the unit to full design capacity.
Copper alloys, titanium and upgraded carbon steel are selected against the specific water chemistry, engineered rather than guessed.
Yes. Our shell & tube and plate exchanger ranges cover conventional and renewable generation equally, all to HEI and ASME standards.
Emergency crews and spares mobilise from Mussafah rapidly, since a single cooler failure can trip a unit and every hour of forced outage carries a direct cost.
Yes. We plan and execute retubing, cleaning and overhaul campaigns inside fixed outage windows, with documented coverage for every exchanger.
Yes. Dolphin Group is ADNOC-approved and ICV+ certified — one of roughly 70 ICV+ certified companies in the UAE.
