Tank Cleaning Machine | 360° Rotary Marine Tank Washer for Oil & Chemical Tankers

Product Overview — Marine Tank Cleaning Equipment

Our tank cleaning machine is a high-performance, dual-nozzle rotary washing device engineered specifically for tank cleaning systems aboard oil tankers and chemical tankers. Featuring a practical design and compact mechanism, these units deliver thorough washing coverage for tanks of all sizes.

Constructed from corrosion-resistant stainless steel for marine environments, this tank washer is available as permanently installed systems or portable configurations. The compact stainless steel construction resists saltwater corrosion and chemical exposure, ensuring long-term reliability and minimal maintenance.

How It Works — Dual-Axis 360° Rotary Cleaning System

The core cleaning mechanism utilizes a hydraulic-driven dual-nozzle rotary system. Water is fed into the machine through the inlet connection, and the hydraulic pressure of the incoming water itself drives the internal turbine mechanism. This self-powered design eliminates the need for external motors or electricity, making it intrinsically safe for use in explosive atmospheres commonly found in oil and chemical tanks.

Dual-Axis Rotation Mechanism

1. Vertical Rotation (Nozzle Axis): The two high-pressure nozzles rotate 360 degrees vertically, creating a sweeping vertical spray pattern that covers the full height of the tank interior from top to bottom.
2. Horizontal Rotation (Body Axis): The entire machine body simultaneously rotates 360 degrees horizontally, distributing the spray evenly across the tank’s circumference and covering all wall surfaces.
3. Combined Coverage: The combined motion of both vertical and horizontal rotation ensures complete, dead-angle-free cleaning of the entire tank surface — from top to bottom and wall to wall. No area remains unwashed.

This dual-axis rotation technology makes our tank cleaning machine significantly more efficient than single-nozzle or fixed-spray systems, reducing tank cleaning time and improving washing quality for cargo tank cleaning operations.
