Spare parts for PureNOx separators

As a vital part of your Exhaust Gas Recirculation (EGR) system, your Alfa Laval PureNOx module needs spare parts that uphold its critical water treatment function. Alfa Laval genuine spare parts provide reliable high performance, which is why they’re the only ones you should use to keep your overboard discharge safe and compliant.

Why choose spare parts from Alfa Laval?

The easiest and most cost-efficient way to stay discharge compliant is to keep your EGR water treatment system running well. By cleaning EGR bleed-off water, PureNOx prevents illegal discharge of polluted water into the sea – and avoids costly offloading to port facilities. Alfa Laval genuine spare parts maintain the best possible protection, thanks to their precision-engineered fit and fully optimized, long-lasting materials.

Consequences of the wrong spare parts

Any loss of separation performance – or worse, a breakdown of the EGR water treatment system – could be catastrophic, especially if the vessel is in a Tier III area. Bleed-off water will accumulate continuously when the EGR system is running. If it can’t be treated, the options are limited:

  • Turning the EGR system off, which is illegal in a Tier III area and can result in heavy fines for air pollution. For vessels using EGR to lower fuel consumption in Tier II, the result will be a higher fuel cost.
  • Filling up the EFG drain tank (if large enough) and discharging the bleed-off water at a port facility. Many ports consider EGR water to be chemical waste, and the offloading cost can range from USD 150 to USD 6000 per cubic metre.
  • Discharging untreated bleed-off water into the sea, which is the last resort if EGR continues and the EFG drain tank is too small. This is illegal and can be punished in the same way as other oily water discharge, with fines up to USD 40,000,000.

Maintaining PureNOx with Alfa Laval genuine spare parts is an easy way to avoid a needless, expensive situation.

Convenient PureNOx service kits

To make preventive maintenance easy, Alfa Laval experts have created service kits for PureNOx. Instead of ordering individual spare parts, you get all the parts you need for a specific maintenance service. Kits are available for the separator, pumps and oil content monitor (OCM):

  • Overhaul kits
  • Pump service kits
  • OCM service and verification kits

Other spare parts for your PureNOx system

Don’t trust your compliance to anyone but the original manufacturer of your EGR water treatment system. Turn to Alfa Laval for all your PureNOx spare part needs:

  • Original spare parts
  • Recommended on-board spare parts

Note that correct spare parts are just one part of staying compliant. EGR regulations demand calibration of your water treatment system every five years, but many other actions are needed to secure compliance in the time between. The PureNOx Compliance Service Package includes parts needed for scheduled maintenance, Performance Audits and calibration service and training.
