NLB water jetting is a highly productive, economical surface preparation method that produces a "white metal" finish - up to the WJ-1 international standard. The process leaves a surface profile free of bent peaks, which trap contaminants that cause corrosion. And it's spark-free and virtually dust-free, protecting the surrounding area as well as personnel. |

Cleaning rates with 40,000 psi (2,800 bar) water jetting are as good as -- or better than -- those of abrasive blasting, but with 98% less residue left behind. Abrasive blasting also leaves over 1,500 times as many airborne lead particulates, according to a 1998 report by the National Shipbuilding Research Program. |

The versatile HydroPrep™ system makes tough jobs easier while it reduces costs. It's a complete package that includes a rugged ULTRA-CLEAN® pump and your choice of manual, automated or semi-automated accessories, as described below. We also have specialized units for cleaning floors and decks or ship bottoms. |
Semi-Automated - VertaJet™ Model SRT-6-6LT is guided by an operator. Rotating water jets need no air supply. It includes vacuum recovery to simplify disposal and clean-up.
|
 |
 |
Automated - SRT-10-W Crawler maximizes productivity, stripping surfaces that people can't easily reach while containing water and debris. No automated system has greater mobility. Features wireless controls and vacuum recovery.
|
Floor and Deck - Vortex™ 36-9950-15A puts a powerful SPIN JET on wheels, with vacuum recovery. Aluminum body and adjustable handle make the operator's job easy.
|
 |
 |
Manual - With a hand-held lance (this one features a rotating head), an operator directs water jets exactly where they're needed.
|
Another NLB innovation, the self-propelled SBC36-8300-15A Ship Bottom Cleaner, uses patented SPIN JET technology to remove ship bottom coatings.
