A quality product

The Alfa Laval GJ A tank cleaning devices are part of our highly acclaimed Gamajet product range. Alfa Laval technology combines pressure and flow to create high impact cleaning jets that are precision engineered to rotate in a precise, repeatable and reliable 360-degree pattern.

Positive return on investment

The unique design reduces your cost to clean and environmental footprint by minimizing the amount of water, energy and cleaning agents required to clean tanks. Using high-impact jet cleaning instead of traditional ineffective static spray ball reduces waste and resource consumption.

Jak to funguje

High-impact, low-resource cleaning

The high-impact jet stream from the rotary jet head is preprogrammed to cover the inside of the tank in a continually denser pattern. This achieves a powerful mechanical impact with a low volume of water, acid or caustic. Most of the Alfa Laval GJA rotary jet heads are capable of operating at both high and low pressures.


Energy-efficient design

A faster tank cleaning cycle also cuts energy consumption. Cleaning fluid flows through the nozzles in an automated, geared rotation around the vertical and horizontal axes. In the first cycle, the nozzles lay out a coarse pattern on the tank surface, with subsequent cycles progressively densifying the pattern over the course of eight cycles.
