The range of Alfa Laval GJ A Series:
GJ A2, GJ A6, GJ PF FT
Focused on product development and engineering, the operations team at Alfa Laval is dedicated to evolving their product line and improving upon existing machines. The Alfa Laval GJ A2 was created as a solution for pharmaceutical cleaning needs, but works cohesively in any sanitary environment. Self-cleaning, self-flushing, and self-lubricating, the machine requires no oil or grease in the gear train and can withstand higher flow rates, resulting in higher impact cleaning. It is also resistant to deionized water—all while maintaining a longer shelf life than its prototype.
Capable of both permanent and portable installation, the GJ A2 is ideal for effective cleaning of small tanks, up to ten inches in diameter, in a repeatable and reliable 360° pattern. Like other Gamajet tank cleaning machines, the GJ A2 is entirely fluid-driven with no external motors, therefore eliminating the need for power assistance.

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.
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.

(3kg at 1.5m)
Cleaning Range: 7.5′ (2.5m)
Pressure: 20-200+ psi (2-14 bar)

Designed to fit through a two inch sanitary fitting, the Alfa Laval GJ A2 is part of the world-renowned Gamajet range of high impact tank cleaning devices. It is the perfect alternative to time-intensive spray balls and costly manual cleaning. Consisting of Food and Drug Administration (FDA) compliant materials, this device is flow-through in design, requiring no grease or oil in the gears. Compact and efficient, the Alfa Laval GJ A2 allows for space saving, while maintaining the impact, durability, and range required for optimal rotary impingement tank cleaning in sanitary environments.
The choice of nozzle diameters can optimize jet impact length and flow rate at the desired pressure. As standard documentation, the Alfa Laval GJ A2 can be supplied with a “Declaration of Conformity” for material specifications.
The Gamajet range of high impact tank cleaning devices combine pressure and flow to create high impact cleaning jets. Cleaning occurs at the point at which the concentrated stream impacts the surface. It is this impact and the tangential force that radiates from that point which blasts contaminants from the surface, scouring the tank interior. In conjunction with this impact, the device is engineered to rotate in a precise, repeatable, and reliable 360° pattern. This full-coverage, global indexing pattern ensures the entire tank interior is cleaned, every time.

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.
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.
The Alfa Laval GJ A product line fits through openings as small as 5 cm (2”) and is ideal for retrofit applications to replace resource-heavy static spray balls through existing tank top connections. Features of the Alfa Laval GJ A product line include self-cleaning and self-draining capabilities.
The revolutionary Alfa Laval GJ A6 tank cleaning machine is designed for permanent installation and to provide true germ and bacteria-free cleaning to meet the demands of the beverage, food, pharmaceutical, and personal care industries.
The design of the GJ A6 tank cleaning machine completely eliminates all areas for potential bacteria growth, making it ideal for sanitary cleaning applications. Variable flow rates and a consistent 360° spray pattern ensure reproducible and repeatable cycles that provide thorough and verifiable cleaning. Its compact size fits through a standard three inch sanitary fitting, and its light weight makes for easy handling and maneuverability.
The Alfa Laval GJ A6 tank cleaning machine is patented and represents the first validatable method of providing true aseptic tank cleaning from a permanently installed impingement cleaner for sanitary applications.
