PureSOx
As the marine industry evolves, there are still good reasons to choose a SOx scrubber. Alfa Laval PureSOx offers economical fuel sulphur compliance, both with global limits and with those in the expanding number of Emission Control Areas (ECAs). Effective in open-loop or closed-loop scrubbing, PureSOx can be delivered as a hybrid scrubber system with both open-loop and closed-loop modes. Just as importantly, it comes with Alfa Laval’s long experience and global service backing.
Alfa Laval is your partner in SOx compliance
- Over 100 years of marine industry experience – including over 50 years of marine scrubber experience
- Proven removal of SOx (>98%) and particulate matter through exhaust gas cleaning
- Hundreds of marine scrubbers in proven SOx compliance worldwide
- A truly global network for scrubber service and support, offering scrubber spare parts, scrubber training, scrubber maintenance and more
- Opportunities for continuous scrubber optimization
Since the first PureSOx scrubber system went to sea in 2009, Alfa Laval has kept vessels in fuel sulphur compliance and SOx scrubbers working at their best. Besides having lower fuel costs, PureSOx owners benefit from Alfa Laval’s long experience, high production quality and deep scrubber knowledge.
PureSOx scrubber systems are compact and handle multiple exhaust gas sources. They are available in open-loop, closed-loop or hybrid scrubber configurations, with Alfa Laval’s leading water treatment technology to support closed-loop operation. Installed smoothly on hundreds of vessels, all PureSOx systems are in compliance today. Consequently, their owners continue to trust Alfa Laval for regular service and ongoing optimization.

Securing compliance with care – service examples
Our portfolio contains a wide range of services to secure SOx scrubber performance. By taking advantage of preventive maintenance, continuous optimization and more, you can rely on your PureSOx system for cost-effective compliance throughout your vessel’s lifetime.
PureSOx spare parts can be shipped anywhere within 24 hours, and we can even arrange tailored stocks.
Sail efficiently between compliance zones, no matter how your PureSOx system was originally configured. FLEX Mode lowers OPEX through either energy or fuel cost savings.
Safeguard compliance and reduce the risk of unscheduled downtime by letting us identify potential issues – along with opportunities for optimization and upgrades.
Use your time in dry dock to increase the lifetime and efficiency of your PureSOx system. Pre-inspection through a Condition Assessment lets us tailor a proposal.
Simplify proof of compliance by swapping in pre-serviced units when calibration or replacement is required. Available for compatible water sensors and gas analyser modules.
Annual gas analyser calibration
If your PureSOx system has a gas analyser from ABB, we can handle the yearly calibration as a certified ABB service partner.
Optimize scrubber performance and lower cost of ownership by increasing crew skills in maintenance and troubleshooting.
Simplify compliance reporting and troubleshooting with data-driven services. Our modular, subscription-based platform helps you save both time and money.
Customized scrubber service agreements
Alfa Laval Service Agreements are a tailor-made way to lower OPEX and secure scrubber uptime. They combine your choice of services from our broad PureSOx offering, ranging from scrubber spare parts to scrubber connectivity. Over 80% of PureSOx customers take advantage of the peace of mind and predictable annual costs.
Why use a scrubber to meet SOx regulations?
Fuel prices are unpredictable, but high-sulphur fuel is consistently less expensive than low-sulphur options. With a PureSOx scrubber, you can leverage the price difference while reducing SOx emissions to the equivalent of low-sulphur fuel. You get lasting fuel economy – and a rapid return on your SOx scrubber investment.
Installing an Alfa Laval PureSOx scrubber system
It takes experience and expertise to get a SOx scrubber system on board, especially in a retrofit. Alfa Laval has delivered hundreds of PureSOx systems, and more than half have been retrofit projects. Our advance planning and proximity to major shipyards, along with prefabricated components and modules, simplify the process.
Over the years, we have developed strong project management routines and procedures. These ensure that design, installation, commissioning and class approval all go smoothly. We take responsibility and work closely with you, the shipyard and any engineering company to ensure success.

Technology
Open-loop, closed-loop or hybrid scrubbing?
Open-loop scrubbers, which discharge the scrubber water directly, are a common choice due to their lower CAPEX and OPEX. However, low water alkalinity or local bans on open-loop scrubbing can limit their use. Closed-loop scrubbers recirculate the scrubber water and discharge only a small amount of cleaned bleed-off water, which enables more widespread compliance. But the smartest choice is often a hybrid scrubber, which provides future-proof economy through open-loop and closed-loop modes. All three configurations are possible with PureSOx.
Sail efficiently between compliance zones with FLEX Mode
If your Alfa Laval PureSOx system was configured specifically for ECA or global operation, moving between compliance zones poses challenges. An ECA-configured system uses more water and energy than necessary in global waters, while a globally configured system is non-compliant in ECA waters. Upgrading PureSOx with FLEX Mode lets your vessel move freely between compliance zones, with lower operating costs and no changing fuels.
Performance and sustainability improvements
Optimize your existing PureSOx system by implementing more recent advances and replacing degraded or obsolete components. With our standardized upgrade packages, you can benefit from design or equipment improvements made after your scrubber was installed. These can help minimize downtime and keep your system operating at its best, improving performance, reliability and sustainability.
Standardized upgrades for PureSOx are defined by equipment type. You’ll find them under Documents above, organized into these categories:
- Electrical cabinet upgrades (ELC)
- Gas analyser upgrades (GAP)
- Scrubber section upgrades (SCR)
- Water analyser panel upgrades (WAP)
- Water cleaning unit upgrades (WCU)
