Marine Equipment
In order to use electrical or electronic equipment in a marine environment, it is necessary that they have additional protection to prevent oxidation and corrosion of the components. Propace Ingeniería offers circuit breakers, alternadotrs, controllers and cabinets with marine certification, Equipment with a long lasting life when installed in coastal or marine areas.
Terasaki switches, thanks to their certification for marine use, are designed to withstand marine environments, even when installed on the coast, which, thanks to the treatments applied as well as the materials used in their construction, ensure operation and/or replacement and parts for at least 25 years. Standard switches for industrial use (offered by our competitors) are not recommended for marine applications, because their main contacts will produce rust on their terminals, and in the case of electronic switches, the integrated circuits (resistors, diodes, capacitors, etc.) are very prone to oxidation, increasing the risk of failure in the operation and activation of each of the protections.
In the case of Mecc Alte controllers for marine use, protection is applied to all integrated components with dielectric varnish, to prevent corrosion to appear due to high relative humidity and salinity in harsh marine environment that causes irreparable damage to the controllers.
That is why TERASAKI circuit breakers and MECCALTE controllers have been tested to meet the highest standards to withstand the hostile marine environment. These standards ensure that the equipment can withstand:
- High temperatures: very common in a vessel's engine room.
- Terasaki circuit breakers: Terasaki equipment can operate at extreme temperatures up to 65°C and their trip curves are calibrated at 50°C (in comparison of a standard circuit breaker, wich barely withstand 40°C, and at higher temperatures, they trip suddenly without any overload or short circuit).
- Mecc Alte controllers: designed to work at temperatures up to 70°C, and with IP65 protection, which makes them resistant to water splashes and any other liquid present on a vessel.
- Vibration: produced by strong sea currents when a vessel is at sea or even by the impact of a torpedo on the vessel's hull.
- Terasaki breakers: tested to remain in the "closed" position and operate at +/-1mm amplitudes of 2-13Hz and 13.2-100 Hz at 0.7g acceleration.
- Mecc Alte controllers: MeccAlte marine controllers are designed to withstand vibrations of +/-1.6mm at 5-25 Hz and 25-100 Hz at 4g acceleration, as well as impacts with accelerations of 200 m/s2, which ensures engine operation even when a storm is present at sea.
- Humidity: characteristic factor of the ocean that accelerates the degradation of equipment.
- Terasaki breakers: Terasaki breakers, thanks to their certification for marine use, are designed to last, even when installed on the coast, which, thanks to the treatments applied and the materials used in their construction, can work at relative humidities of up to 95%.
- Mecc Alte controllers: MeccAlte controllers, especially those certified for marine use, are tested to withstand relative humidity up to 95%.
The good operation of a vessel depends largely on the electrical system and the reliability of its thrusters and generators. That is why it is necessary that breakers and controllers have certifications for marine use. MeccAlte and Terasaki equipment are certified by the most important entities in the marine sector:
- ABS: American Bureau of Shipping, USA.
- Lloyds Register, UK.
- Bureau Veritas, France.
- Rina, Italy.
- GL-DNV: Germanischer Lloyd- Det Norske Veritas, Germany-Norway.
- Nipon Kaiji Kyokai, Japan.
- CCC: China Classification Society, China
We recommend the use of this equipment on all vessels to ensure functionality and operation at all times.
Marine alternators
Propace has Mecc Alte marine alternators on its product lines, the world leading alternator manufacturer. We offer a diverse range of marine alternators from small water-cooled specialized products up to fully advanced marine products. This alternators work good for both essential and non-essential loads, at small boats or large vessels.
There is a wide range of requirements in marine applications. It is important to have a standard product that suits the vast majority of these applications– either by standard features or by adding simple accesories. The 12 wire reconnectable, multi-purpose winding helps to configure the output voltage to a wide range of voltages and Frecuencies.
Besides, there are many dedicated windings if required – such as 690V 50/60Hz for windfarm support boats. The IACS IP23 mandatory requirement is a standard feature in our alternators. Enhancements can be supplied to upgrade its degree of protection (ingress protection), from IP43 to IP45 levels. It is recognized that certain installations require higher levels of protection due to engine room fire protection systems. Derates will apply.
Even the standard construction fulfills the mandatory requirements of most installations – including 300% SCC for up to 10 seconds, there are other options available, if required, to satisfy a given specification.
