Ekstrom & Son

Helixchanger saves you valuable energy and space

Ekstrom & Son’s Helixchanger shell and tube heat exchangers are certified by Lummus (CB&I).

Successive baffles create continuous helical and near plug-flow conditions on the shell side enabling energy savings of up to 50%, which results in improved thermal effectiveness and enhanced heat transfer.

This also leads to fewer pressure drops, lower fouling and significantly reduced vibration hazards. Pay-back time could be as short as one year compared with a conventional heat exchanger.

Backflushing valves for plate heat exchangers

Fouling and clogging of plate heat exchangers cause problems for the industry.

Ekstrom & Son’s Smart Loop backflush heat exchangers at short intervals without interrupting the operation. By changing the direction of the flow, particles are flushed out. It also prevents biofouling, for instance, build-up of algae and other organisms.

The Smart Loop valve extends the time between maintenance periods, as well as improves performance and generates additional energy savings of up to 50%.

Customised pressure vessels

Ekstrom & Son designs vessels according to the requirements of its clients and is certified by the ASME (American Society of Mechanical Engineers) code, which is applied to plant design, manufacturing, installation, maintenance and improvement services.

The company also complies with various industrial codes, including:

• Achilles JQS, NORSOK
