Problem: A pharmaceutical
company — which manufactured a
wide range of active pharmaceutical ingredients — experienced
significant revenue loss due to
their tank cleaning procedure.
The company found itself under
pressure to provide a more
validatable clean and also to
eliminate confined space entry.
Three processing tanks with
center agitators were costing
them $9,000 each in revenue for
every hour of downtime.
The company’s regular cleaning procedure included five
hours of manual cleaning done
every three days. In addition, a
20-hour manual clean was performed by the company every
Solution: The company
implemented two Gamajet A6
rotary impingement tank cleaning
devices, powered by a Gamajet
Mobile Cleaning System. The systems were configured to operate at
120 PSI and 10 GPM (per device).
Cleaning with the rotary
impingement devices included a
15-minute open cycle pre-rinse to
remove the bulk of the residue, a
30-minute recirculated wash with
a 2 percent caustic concentrate,
and a final 15-minute uncirculated
As a result, the com-
pany was able to save
71 percent of water
and chemical usage
and 82 percent of time spent
cleaning. They were also able to completely
eliminate the need for manual cleaning. Ad-
ditionally, the company recovered over $5.1
million in lost revenue.
Purchased by Alfa Laval in 2012,
Gamajet, as part of the Alfa Laval Group,
provides all types of tanks and vessels as
Alfa Laval Tank Equipment.
The rotary impingement cleaning
method is suitable for personal care and
pharmaceutical manufacturers, food and
beverage manufacturers, breweries, trucking fleets, municipalities, wineries, and
The tank cleaning devices combine
pressure and flow to create high impact
cleaning jets. Cleaning occurs at the point
in which the concentrated stream impacts
It is this impact and resulting tangential
force that radiates from that point and
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-degree pattern.
This full-coverage, global indexing pattern ensures the entire tank
interior is cleaned, every time.
