Alfa Laval- GJ A Series
The Alfa Laval GJ A product line offers tank cleaning devices that deliver powerful, efficient, hygienic cleaning for companies within the food, beverage and personal care industries. They are ideal for retrofit applications to replace resource-heavy static spray balls and costly manual cleaning. Features of the GJ A includes self-cleaning and self-draining capabilities and the ability to clean tanks through openings as small as a 5cm (2”).
The range of Alfa Laval GJ A Series:
GJ A2, GJ A6, GJ PF FT
Alfa Laval Gamajet A2 (GJ A2)
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.

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.
Impact: Up to 7lbs at 5′
(3kg at 1.5m)
Cleaning Range: 7.5′ (2.5m)
Pressure: 20-200+ psi (2-14 bar)
Flow: 5-30 gpm (20-110 lpm)
Clearance: 1.85″ (47mm)
Cycle Time: 4-20 min.
APPLICATION
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.
STANDARD DESIGN
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.
WORKING PRINCIPLE
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.

Application
The proven The Alfa Laval GJ PF FT is a high-impact tank cleaning apparatus from the esteemed Gamajet series. It has been demonstrated that corporations can conserve up to 85% on water, time, energy, and resources in comparison to static spray balls. This device can clean tanks with capacities between 5,000 and 25,000 liters.
The Alfa Laval GJ PF FT Rotary Jet Head can pass through openings as narrow as four inches and functions at low pressures and flows to sanitize tanks in high-impact cleaning scenarios, including ethanol, paper, pulp, chemical, steel, and industrial fermentation processes. Companies that use this equipment into their tank cleaning procedures save time and enhance production.
Working Principle
The Gamajet series of high-impact tank cleaning apparatus integrates pressure and flow to generate powerful cleaning jets. Cleaning transpires when the directed stream makes contact with the surface. This impact, along with the tangential force originating from that place, dislodges impurities from the surface and cleanses the tank inside. Moreover, the device is engineered to rotate in a precise, repeatable, and consistent 360° manner. This comprehensive global indexing pattern guarantees the complete cleaning of the tank’s interior.

Validate your tank cleaning process
Alfa Laval Rotacheck validates the rotary jet heads cleaning process, reduces water consumption and product loss. Provides peace of mind.
High-impact, low-resource cleaning
The high-impact jet stream from the rotating jet head is preconfigured to uniformly coat the tank’s interior in an increasingly dense pattern. This generates a significant mechanical impact with a minimal volume of water, acid, or caustic substance. Most GJ rotary jet heads are capable of functioning at both high and low pressures.
Smoother, long-lasting performance
The Alfa Laval GJ rotary jet head line features a unique, grease-lubricated gear that prevents potentially harmful particles from becoming trapped during CIP recirculation. This innovative design enhances performance while simultaneously reducing wear and strain.
Energy-efficient design
Less energy is used when the tank cleaning cycle is faster. Moving cleaning fluid through the tubes is done automatically by gears that turn them around the vertical and horizontal axes. During the first turn, the nozzles make a rough pattern on the surface of the tank. The pattern gets denser over the course of eight rounds.
