Daros can supply rings to all Wärtsilä Sulzer engines in operation in the following versions:
|WÄRTSILÄ (SULTZER) ENGINES||Basic version||Quick running-in version||Heavy-duty version|
|RTA 38 & 68||X|
Basic version: Basic ring set-up consisting of rings made from Daros’ unique base material, providing reliable operation in combination with the standard liners.
Quick running-in version: Running surface has a coating for improved running-in, ensuring a fast sealing that will enable a minimum running-in time at shop trial and after overhaul (current standard).
Heavy-duty version: The running surface is coated with a hard coating, resulting in longer time between overhaul (TBO) and increased scuffing resistance.
Optional: To prevent ring groove wear, Daros can also offer hard chromium coating on the underside of the rings in order to extend the lifetime of the piston’s ring grooves.
