Case Study: Pfannenberg Thermal Management Solutions for Harsh Marine Environment


Customer Requirement

An OEM machine builder in the Marine industry needed a thermal management solution that was NEMA Type 4/4X rated, but also resistant to highly corrosive salt spray (fog).  In an industry that encounters very harsh environments, it is crucial to be able to have a product that will be able to withstand such conditions.

The Pfannenberg Solution

To meet the customer’s specific requirements, we provided our PWS Air to Water Heat Exchangerswith the 316 Stainless Steel option.

We offered a unit:

  • Which is very resistant to corrosion and oxidation (316 Stainless Steel) compared to the 304 Stainless Steel
  • That can be configured with a different heat exchanger when salt water is used for the cooling supply water
  • With an “easy to mount” seal, no elaborate reworking of the mounting cut-out
  • With an integrated thermostat and solenoid valve for temperature control

Customer Benefits

The customer was satisfied with these highly resistant units that are perfectly adapted to marine environment. Thanks to Pfannenberg’s Air to Water Heat Exchangers the customer was able to reduce downtime and maintenance costs.
