Comparison: Vicmar and Existing Washing Systems

Washing of the Turbocharger (blower)

Disadvantages of existing washing systems
from a design point of view
  • Cold water is used for cleaning.

  • Insufficient amount of water utilized as standard water pots are only 1.5 -3.0 L.

  • Scavenging air used to inject water. Resulting pressure is very low and not sufficient for removal of deposits

Disadvantages of existing washing systems
from an operational point of view
  • Water is not connected to the water pot. It is necessary to manually fill the pot which results in the deferral of the washing by the crew

  • Cold water used which does not completely dissolve oily deposits, resulting in the blower operating in fouled conditions.

  • Existing systems are designed by the turbocharger manufacturers only for cleaning the blower. Blower deposits are transferred to air cooler, plugging the fins, resulting in increased exhaust gas temperature and fuel consumption

Advantages of Vicmar’s Washing System
from a design point of view
  • Hot water used for cleaning

  • The water tank is customized according to the size of the turbocharger

  • Compressed air of optimum pressure is used to inject water in order to provide sufficient water pressure to remove deposits.

Advantages of Vicmar’s Washing System
from an operational point of view

  • Water is connected to the water tank resulting in simple filling of the tank by opening the water supply valve

  • Hot water is used for washing which removes the deposits from the blower, maintaining clean blower conditions

  • The Vicmar Washing System safely cleans the blower simultaneously with the air cooler ( at engine full load)

Washing of the Air Coolers

Disadvantages of existing washing systems
from a design point of view

  • Cold water is used for cleaning

  • Size of the water tank is insufficient for cleaning as it does not take into consideration the size and the number of air coolers

  • Water is injected inside the air cooler trunk via two pipes, which have very few orifices. These orifices do not cover the entire surface of the air cooler and can not effectively complete full washing

  • In many instances, water and/or compressed air is not connected to the water tank and thus it is necessary to complete this manually

 Disadvantages of existing washing systems from an operational point of view

  • The cleaning procedure of the air cooler occurs when the engine is shut down or on reduced load.

  • Cold water can not dissolve and remove the deposits

  • Chemicals can be used for cleaning of the air cooler (while shut down) which increases the maintenance cost and human error with mixing and preparation. Blocked fins will result if chemicals are not properly rinsed from the air cooler

  • Existing washing systems have proven it necessary to remove the air cooler for cleaning during the dry-dock period. This is a costly procedure with increased risk of fin damage during transportation

Advantages of Vicmar’s Washing System
from a design point of view

  • Hot water is used for cleaning

  • The water tank is customized to the size and number of air coolers. Engine output power is considered for the size of the water tank

  • The water is injected inside the air cooler via 8 – 10 specially designed injectors, each of them equipped with 120- 150 orifices. The entire surface of the air cooler is reached by the water

  • Hot water and compressed air are connected to the water tank

Advantages of Vicmar’s Washing System
from an operational point of view

  • Washing procedure takes place on the daily basis simultaneously with the blower and it is performed while the engine is operating at full load

  • Hot water is more effective in dissolving and removing the deposits

  • No chemicals are used for air cooler cleaning

  • No need to remove and clean the air cooler during dry-dock thus reducing maintenance costs
