We can replace your existing Marine Boiler with new PARAT boiler with exactly the same outer dimensions.


Retrofit by PARAT Halvorsen AS

Built after original drawings exactly to the same outer dimensions as the old one, which means it can be used with the same available space and existing connections. (small modifications is sometimes required). We can make smoke tube boilers, water tube boilers, economizers for oil burners, gas burners, waste heat etc.

At such projects we have a skilled and experienced technical department with good knowledge of boilers and boiler plants for construction, technical planning and documentation. With our large and skilled service team this can be done as a complete installation, including demounting and mounting of the boiler in the ship.

PARAT are one of the few boiler manufacturers who are able to customize such assignments to optimize boiler plants according to our customers’ needs.
