Alfa Laval acquires anti-fouling firm

NRG Marine’s ultrasonic systems use microscopic bubbles that disrupt surfaces to prevent fouling, scaling and sludge accumulation, resulting in reduced maintenance and improved performance.

“In the race to net zero, solutions that enhance energy efficiency and operational performance are more essential than ever,” said Sameer Kalra, president Marine Division, Alfa Laval.

“By addressing the critical problem of biofouling with this advanced technique, we will enable our customers to meet both business and environmental objectives.”

In marine applications, the technology reduces fuel use and combats biofouling which contributes to the spread of invasive species. The system provides an eco-friendly alternative to traditional cleaning methods, reducing the use of harsh chemicals and minimising downtime.

The ultrasonic technology is also beneficial for the oil and gas sector, where it helps maintain stationary surfaces by preventing biofouling. It is ATEX-approved, ensuring safety in hazardous environments.

Alfa Laval’s acquisition of NRG Marine marks a significant step towards providing advanced, cost-effective solutions that improve efficiency while minimising environmental impact.

“We are excited to join forces with Alfa Laval through this acquisition to extend ultrasound technology for anti-fouling treatment to marine, oil and gas, and other industrial sectors,” said Darren Rowlands, founder & chief executive of NRG Marine.

“This strategic move will increase our market reach and scalability, making our solution more accessible to customers.”

The acquisition is expected to close by Q2 2025.
