How it works


Efficient: Do more with less

Understanding Cleaning

There are four factors that can be manipulated in any cleaning scenario: temperature, chemical reaction, time, and mechanical force. When the effectiveness of any factor is increased, it will result in a decrease of one or multiple other factors. Washing dishes is an effective example of how the four factors interact. How water (temperature) is going to remove stuck on food better than cold. Adding soap (chemical reaction) makes the process even easier, and you can either soak a dish overnight (time) or scrub the dish clean (mechanical action). Our rotary jet heads maximize mechanical action, resulting in a drastic reduction of the three remaining factors; time, chemical and temperature.

Optimizing Impact through Design

Our rotary impingement devices are designed to offer the optimal output of force with the least flow and pressure to create the most effective and efficient cleaning. With decades of experience in tank cleaning, we know the specific amount of force it takes to clean nearly every vessel. For example, we know that it takes 15 lbs. of force to clean the interior of a polyurethane tote with dried on paint residue. To achieve that 15 lbs., our Alfa Laval GJ 9 configured with a large stator and 1.50 nozzles at 19 gpm and 700 psi would easily do the job. What makes this statement even more significant is that we can honestly say that this is the most efficient and effective way to obtain that force.

Limited leakage

Many machines suffer from a significant amount of leakage. Rotary impingement machines are designed to optimize the flow going into the machine. If a majority of that flow is getting lost throughout the cleaning process the force on the interior of the tank is reduced. Our devices use the highest percentage of flow going into the machine, with a small volume of controlled leakage designed and implemented into the machines to reduce pressure and clean the machine. The percentage of leakage permitted is typically less than 3%. (See chart below for comparisons)
