Keelcrab

Tested and certified for use on Greenhull treatment

What is Keelcrab Pro?

Keelcrab Pro is a professional underwater robot for cleaning, maintenance and inspection of yacht and pleasure boat hulls, equipped with a complete kit of optionals designed to meet the needs of the most demanding professionals in the nautical sector.

The Keelcrab drone is therefore supplied with a set of accessories (tangible and intangible) designed to best support the carrying out of service, inspection and hull cleaning activities of your customers in the marina.

Thanks to Greensailor a specially dedicated set of brushes suitable for Greenhull and Greenprop paints had been released after numerous tests and experiments for which Keelcrab drones have become recommended Greensailor Products!

Keelcrab Pro  is the first of the new generation of underwater drones entirely designed and built in Italy (100% made in Italy) to carry out  robotic cleaning, maintenance and hull inspection activities.

Characterized by an exoskeleton in plastic material with neutral hydrostatic buoyancy, it maintains  perfect adherence to the hull  thanks to an important suction effect generated by a powerful marinated pump motor, removing and sucking up algae or vegetation that typically form on the hull of boats during periods of rest in closed waters.

The movement of the drone is guaranteed by  natural rubber or PVA brushes driven by tracks  which allow easy maneuvers in all directions, on any surface and making the drone capable of overcoming obstacles.

The  high-resolution underwater camera  allows the drone to be operated using a cable remote control with display of the video stream on a 7-inch display, tablet or phone (optional) in high resolution.

Keelcrab PRO 23 can also be equipped with the preparation for the  Diver pack,  i.e. the Kit for using your keelcrab in “manual control” mode while diving (freediving or SCUBA/ARO). The kit consists of 2 side handles and an IP69 switch to activate the traction motors (to be able to activate or stop the advancement of the robot and the relative dragging effect of the diver on the hull). As regards cleaning capacity, the drone is equipped with  cushioned counter-rotating disc brushes  (15mm excursion/adaptation to the surface) moved by a dedicated waterproofed motor with variable bristles (nylon & stainless steel) to guarantee the best cleaning capacity  interchangeable depending on the abrasion needs.

These  ANCCP certified brushes  with adequate set-up or following the instructions in our instruction manuals,  do not remove antifouling paints but rather extend their effect and their useful life over time. 

Numerous tests have shown that the constant removal of the first layer of vegetation (3/5 mm) causes a drastic extension of the useful life of the antifouling (which returns to direct contact with water) which translates into a great slowdown in the formation of “barnacles” (barnacles) in the medium term, reduction in fuel consumption (and related emissions) and maintenance of navigation performance at the top (thanks to the lower friction of the hull on the water).

The drone is also equipped with a  keelcrab bag filtering system   with variable micrometric nylon filter bag for the recovery of waste material, algae or vegetation, deriving from the cleaning operation. Fundamental to avoid the phenomenon of vegetation reattaching to the hull especially in the presence of very still or stagnant waters or where the boat cannot return to navigation in a short time (typically cleaning operations during the winter season).

The product warranty certificate  is valid for 24 months (excluding consumables) or 500 hours of use.
