Systems and Equipment for Marine Use

Propace Ingeniería provides Systems and Equipment for Marine Use, essential for ensuring the safe operation of electrical and electronic devices in marine environments. To use this type of equipment in coastal areas, it must include additional protection that prevents oxidation and corrosion of its components. For this reason, Propace Ingeniería supplies switches, alternators, controllers, and certified marine-grade enclosures or cabinets. These devices are designed to withstand humidity, salt exposure, and harsh conditions, ensuring long service life in maritime applications.

Certified resistance for harsh environments

High temperatures

Switches: tolerates up to 65°C and its curves are calibrated at 50°C, preventing unwanted temperature-related tripping.
Controllers: operates up to 70°C and has IP65 protection against splashes or liquids in engine rooms.

Vibration

Switches: tested to remain in the “closed” position with amplitudes of ±1 mm between 2–13 Hz and 13.2–100 Hz at 0.7 g.
Controllers: withstands ±1.6 mm between 5–100 Hz, accelerations of 4 g, and shocks of 200 m/s², ensuring operation even during storms.

Humidity

Both devices withstand up to 95% relative humidity, resisting the accelerated corrosion typical of marine environments.

International marine certifications

Terasaki circuit breakers and Mecc Alte controllers comply with certifications from the most recognized naval entities worldwide: ABS (USA), Lloyd’s Register (UK), Bureau Veritas (France), RINA (Italy), GL-DNV (Germany–Norway), Nippon Kaiji Kyokai (Japan), and CCC (China). These certifications ensure total reliability on any vessel.

Terasaki marine circuit breakers

Terasaki circuit breakers, thanks to their marine-use certification, are designed to withstand environments with high salinity, humidity, and corrosion, even in coastal installations. The materials used and the protective treatments applied guarantee reliable operation and a service life of at least 25 years. Standard industrial circuit breakers are not suitable for marine applications, as their contacts and electronic components corrode easily, causing failures and incorrect tripping.

Mecc Alte marine controllers

Mecc Alte marine controllers are protected through dielectric varnish applied to all integrated components, preventing corrosion damage caused by high relative humidity and salinity present on vessels. This prevents irreparable failures and extends their service life even in severe environments.

Mecc Alte marine alternators

Propace offers a wide range of Mecc Alte marine alternators, from compact water-cooled models to advanced units for large vessels. They can be used for both essential and non-essential loads. The 12-lead multipurpose winding allows multiple voltage and frequency configurations. Special windings are also available, such as 690 V versions at 50/60 Hz for offshore support vessels. They meet the IACS IP23 requirement as standard, with upgrade options to IP43–IP45. Their construction can withstand a 300% short circuit for 10 seconds and can be configured for special specifications when required.
