Introducing the Butterworth

MARINE LIQUA-

BLASTER

SHIP MAINTENANCE SYSTEM.

A 10,000-psi jet of water promises to revolutionize routine on-board maintenance... especially rust and scale removal of surfaces to be painted.

Butterworth Systems now offers a modern alternative to the age-old chipping hammer. It's their MARINE

LIQUA-BLASTER"

Diesel powered pump of a

MARINE LIQUA-BLASTER onboard a vessel. ultra-high pressure water- blasting equipment.

Especially developed for shipboard use at sea, the MARINE

LIQUA-BLASTER unit uses a diesel or electric powered pump to generate a 10,000-psi jet of water that is directed by a fail-safe, hand-held gun at the surface being descaled. "White-metal" cleaning.

On a badly rusted surface, "water only" blasting removes scale and debris, leaving a surface that is acceptable for standard maintenance painting. If a moderate amount of sand is automatically added to the water jet, a surface can be "white-metal" cleaned more effectively and more efficiently than it would be with dry-sand blasting in a shipyard.

With the MARINE

LIQUA-BLASTER unit, a rust inhibitor can be added to protect the "white-metal" surface against oxidation before painting.

Better than dry-sand blasting.

Because of the high velocity of the water/sand jet, the sand impacts a rusted surface with a much greater force than with regular dry-sand blasting.

The end result is faster cleaning using less sand.

Sand can cause sparking, so it should only be used in non-explosive environments.

Other shipboard cleaning.

In addition to descaling rusted surfaces, a MARINE

LIQUA-BLASTER unit can be used for a number of other on-board cleaning jobs. These include cleaning condenser and boiler tubes, oil spray from machinery, galley grease filters, clogged ports, and the like. For these jobs, as well as rusted surfaces, a variety of guns, lances, round and fan jet nozzles are available.

Proven on-board use.

The experience on a 69,742-DWT tanker, is typical of other vessels that have used MARINE

LIQUA-BLASTER equipment. Here, it was first used to clean a badly rusted 550-square-meter poop deck. The job was done as routine maintenance with interruptions for bad weather and all-hands tasks. In a little over two weeks the poop deck was "white-metal" cleaned and freshly painted.

Doing the same job in a shipyard would have cost $13,750 at $25 per square meter not including the incremental lay up time to accomplish this task.
