Controlling the harsh extremes of the sea.


Overcoming the challenges of the extremes

The maritime industry is challenged by many extremes – from the artic and tropic temperatures, calm and severe weather conditions, shipping congestion and vast open seas, and cargo from everyday passengers to potentially explosive petrochemicals. Today’s industry has to confront these extremes along with tighter safety controls and ever increasing environmental regulations.


Reliability in any condition

Our products are used in vessel engine cooling systems, propulsion bearings, engine exhaust and air systems, LNG/dual/tri fuel motors, engine fuel oil systems, gas turbines, control systems and more. All devices are designed for easy and low-cost installation (no grounding necessary), easy change of configuration, long-term durability and reliable performance – even under the harsh conditions at sea. All are individually tested and validated before they leave our factory, and are backed by a five-year warranty and global support.


Set sail in safe hands

In addition to SIL to IEC 61511 approvals, you can sail easy with IECEx and ATEX for gas and dust atmospheres, CSA, FM, GOST and UL approved products with Det Norske Veritas (DNV) and/or Germanischer Lloyd (GL) standards for marine-based extraction.

Customer statement:


"We have successfully used PR electronics' relays as Ex barriers for numerous tanker projects for the Arctic region because of the great flexibility, allowing customers to change the configuration where necessary when navigating in areas where it is difficult to obtain service".
