Nozzle Cooling

Name: Nozzle Cooling
Brand: Damen Marine Components (Van der Velden)

Propeller nozzle that doubles as an engine cooler: heated cooling water is routed through the nozzle, where propeller-driven seawater flow gives efficient heat transfer; suited to tugs and workboats.

Description

Nozzle Cooling from Damen Marine Components uses the propeller nozzle as a heat exchanger for the main engines. Heated engine cooling water is directed through the nozzle construction, where the propeller keeps seawater flow speed high, especially when the engines are heavily loaded.

Key features

High water flow rate from the propeller and good heat transfer
Addresses higher cooling demand of smaller, hotter-running main engines
Nozzles produced by single-weld spinning, inside diameters from 1,000 mm to 5.3 m outside, in stainless steel, duplex, steel and special steels

Applications

Various vessel types, especially tugs and workboats.

Alpha Fixed Pitch Propellers

Alpha fixed pitch propellers for ocean-going vessels on long-haul service near the design point, as well as smaller yachts and workboats; low hub-to-propeller diameter ratio and few wearing parts.
