Eco-Energy Cooling System

Azcue Eco-Energy Cooling System

Azcue Eco-Emergy

With the need to reduce costs in an ever challenging market, as well as increasing environmental concerns, energy efficiency is a growing focus for the marine industry. As a result of this, Azcue Pumps have developed an energy saving concept to ensure that only the energy required to operate a pump is used. With on board pumps running at more than the required capacity being a massive factor behind unnecessary energy costs, the Eco-Energy system is a perfect solution for engine cooling systems.

Cut your energy costs & improve your bottom line

The sea water cooling pump system in the engine room is generally designed to cope with worst-case scenarios; it operates as though the sea water temperature is at around 32°C, the temperature of the read sea, and the vessel has maximum load. In reality these conditions are met less than 5% of the time, and real cooling demand is between 50-70% less than the system is designed for, making energy use much above actual requirements.

Using an AC drive frequency converter to control the sea water cooling pump's output, rather than a valve or on-off control, the Azcue’s Eco-Energy System adjusts the speed of the pump to the real cooling demand rather than the most extreme operations conditions. When the sea water is temperature is lower and less cooling is required, the system will slow down the pump and consequently use less energy. This process means that energy consumption can be dramatically reduced, contributing to an increase in the vessel's overall profitability. In real life installations, vessels have experienced energy savings of up to 80%!

Azcue Eco Energy System

As well as saving the shipowner energy costs, the Eco-Energy system results in further savings:

  • Limited mechanical stress
  • Less maintenance required on wearing parts
  • Longer operating life of the pump
  • Reduced risk of cavitation
  • Lower CO2 emissions
