Did you know?
That to generate 1 kWh it requires app.: 190 – 240g Fuel.
That generation of 1 kWh causes emission to the atmosphere of app.: 550g CO2 and 15g NOx.
50% of the consumed kWh on ferry and cruise vessels are used to run lighting, HVAC and pump installations.
Upgrade your lighting, HVAC and pump installations and gain the following savings:
Reduction in the CO2 & NOx emission by 40–60 %.
Reduction in the kWh consumption by 40–50 %.
Reduction in operation costs by 30–50 %.

How to reduce kWh consumption and thereby reduce emission of green house gases to the atmosphere?
Light installations: Almost all light installations are equipped with magnetic ballasts and T8 tubes. Introduction of the latest electronic ballasts and T5 tubes, in combination with dimmer and motion sensor, will reduce the kWh consumption by 50-60 %. Further, due to a heavily reduction in the number of light tubes, as well as increased lifetime of the individual components, the maintenance costs are reduced dramatically. The light installation represent app. 30% of the consumed energy related to light, HVAC and pump installation.
HVAC: Many HVAC installations are oversized in capacity and this together with a lack of a correct duty cycle is causing a huge waist of produced kWh. Introduction of VSD technology combined with heat exchangers and a correct duty cycle of the plant will increase the efficiency of the plant by 40–60 %.
Further implementation of sensors measuring CO2, temperature and humidity will make a contribution to the efficiency of the plant. The HVAC installation represent app. 60% of the consumed energy related to light, HVAC and pump installation.
Pump installations: Seawater cooling system, high and low temperature cooling water systems for main and auxiliary engines are often oversized. Usually the flow is controlled by 2-speed motors and additionally by control of the valves. Surveys have shown that the efficiency of this setup is rather poor.
Introduction of VSD technology in combination with exchange of pump wheels with better efficiency and el-motors with better cos phi (eco-motors), improves the overall efficiency of the systems by up to 50%. The cooling water installations represent app. 20% of the consumed energy related to light, HVAC and pump installation.
On our website, www.scanel.dk, you can find more information and see the results of a survey and upgrading of lighting, HVAC and cooling water installations on a ferry.
EPC: In corporation with our suppliers we are in a position to offer you a EPC contract. The EPC, Energy Performance Contract, offers you to pay the costs to the upgrading of your systems.
