Blue Dolphin heat transfer Red

Heat Exchanger Services

Dolphin’s services are broadly divided into three categories namely
its Industrial Services, Thermal Systems, and EPC Projects.

Dolphin has been providing heat transfer solutions to the industrial sector for more than 30 years. Our customers are major oil companies and process plant operators. With this high value clientele, our products and services are guaranteed to be high quality, enabling our customers to operate efficiently.

All heat exchangers undergo degradation overtime. This wear and tear is inevitable and needs to be addressed periodically. Decreased heat transfer due to fouling, pressure loss due to leakages, and decreased thermal performance due to damaged components are just a few ways untended heat exchangers decrease efficiency.

Our services start with an inspection, after which we can recommend the best course of action when it comes to repairing, cleaning, or servicing your heat exchanger. We believe in being a one-stop-shop servicing center for our customers. Our scope of works includes, on-site removal, thermal design, restoration, testing, installation, and commissioning.

We conduct a full range of services for:

  1. Shell and Tube Heat Exchangers
  2. Air Cooled Heat Exchangers
  3. Plate Type Heat Exchangers
  4. Cooling Towers

If your requirements are not part of the list, there’s no need to worry! Just give us a call and we’ll let you know what we can do for you.
