The Polar Jet® PJ 303 is a fully programmable, multi‐stage, single nozzle Tank Cleaning machine equipped with pitch and speed control. Nozzle movement is fully controlled by the integrated turbine driven control unit, which controls both the vertical pitch and rotation speed. Nozzle movement is, in principle, a controlled rotation in the horizontal plane, combined with a slow, controlled vertical movement. This means that the nozzle performs helical patterns. The PJ 303 comes with operator‐friendly controls to set both vertical Pitch and rotation Speed. There are two Speed Settings and three Pitch Settings of approximately 1.5, 3 and 7 degrees providing six basic programs.


Angle adjustment allows pre‐setting of the Pitch at the start of either the upward or downward cycle for optimal cleaning of specific areas such as bottom only or side only cleaning requirements. Polarmarine provide in‐house Shadow Diagrams using 3‐Dimensional CAD for model Selection, Quantity, Positioning and Main Pipe Lengths to optimize cleaning coverage per unit. The Shadow Diagrams are made according to DNV ETC, Effective Tank Cleaning. Standard material is according to SUS 316L. As optional with higher grade, Stainless Steel with Molybdenum equal or higher than 2.5% is also offered.
