M/V Hermes Leader FWG: Easier Cleaning at 4,000 hrs

Home 9 Case Studies and Results 9 M/V Hermes Leader FWG: Easier Cleaning at 4,000 hrs
Key results
4,000 hours extended operation
9 month service interval
7 kg salt removed easily

The Challenges

  • Scale building up on FWG heat exchanger plates
  • Water production reduced to around 17 m3/day
  • Manual scraping risking plate damage
  • Cleaning downtime needing reduction

The Solution

One HM120 unit was fitted to the seawater inlet pipe to the fresh water generator in January 2015. The signal disrupts the conditions that bond scale to surfaces, so deposits detach easily at cleaning and the risk of plate damage drops.

Key Outcomes

FWG opened after 9 months and 4,000 hours

R

Only minor residue needed light brushing

R

Most accumulated scale detached easily

R

Around 7 kg of salt deposits removed

Independent Verification
