Products & Services


PSS Shaft Seal

The PSS Shaft Seal is a mechanical face seal designed for shafts up to 6" diameter. The PSS replaces a conventional packing gland and reduces scoring on the shaft and also water accessing the bilge. The PSS will reduce maintenance and corrosion in the engine room. The PSS is installed on numerous commercial, Coast Guard and ferry's around the world. Many seals have recorded in excess of 40,000 engine hours! 

SoniHull Ultrasonic Antifouling System

SoniHull Ultrasonic Antifouling Systems is a cost effective antifouling product that compliments conventional antifouling paint. SoniHull will extend the bottom paint life and time between haul outs. SoniHull will also protect seachests, box coolers, pipe work, jet's and other areas that are prone to growth. SoniHull works by producing multiple bursts of ultrasonic energy in a range of targeted ultrasonic pulse frequencies (19.5 - 55 kHz). This produces a pattern of alternating positive and negative pressure. The negative pressure creates microscopic bubbles and the positive pressure implodes the bubbles.  The implosion has a cleansing effect that destroys algae, the first link of the food chain, making the surface less attractive to other marine life that feeds on the algae. The microscopic movement of water also prevents barnacle and mussel larvae from embedding. Visit us at booth #1751 for more details.
