Airseal Insulation Systems of Brooklyn, NY used a Graco Reactor E-30 to apply spray polyurethane foam (SPF) to help build One World Trade Center in New York City, according to a recent article in SprayFoam magazine.
Because of critical deadlines, the concrete for One World Trade Center needed to be poured in sub-freezing weather. The forms needed to be insulated or the concrete wouldn’t cure properly. Using Graco equipment, Airseal Insulation Systems insulated the concrete form for the core shaft of the building. Read more

Reactor® E-Series now offers adjustable pressure offset
Graco® now includes the adjustable pressure imbalance feature on electric Reactors (models E-20, E-30, E-XP1, E-XP2), a feature that was previously only available on hydraulic Reactors (models H-25, H-40, H-50, H-XP2, H-XP3). The pressure imbalance function (status code E24) detects conditions that can cause off-ratio spray, such as loss of feed pressure/supply, pump seal failure, clogged fluid inlet filter, or a fluid leak.
The pressure imbalance default is factory-set at 500 psi (35 bar, 3.5 MPa). This change allows the pressure to be adjusted and set at 100 to 999 psi in 100 psi increments. Values less than 500 would be selected for tighter ratio error detection, while higher values would be selected for looser detection or to avoid nuisance alarms.

Pressure imbalance: “The Gun & Gauges Don’t Lie”
By Barry Taft
In this issue, I would like to take a look at pressure imbalance issues such as an E24 indication in the Reactor® Series or analog gauges reading high or low in other proportioner platforms.
There are many causes for pressure imbalance and we need to focus our attention to the correct area to get us back up and running. I like to say there is no money in machine repair down time. So instead of a “shotgun” approach where you clean every filter, clean the gun, replace mix chambers, swap guns and feed pumps and still can’t find the root of the problem, I propose a more focused approach where we listen to what our guns and gauges are telling us.
A very good friend of mine, Craig Hier with Intech Equipment & Supply liked to call it “The Rookie Rag” approach. This is a great way to teach the concept. If we can determine which chemical – “A” or “B” – is coming out of the gun, then we can place a rag over that side’s gauge and focus on the other side where the problem lies. This will immediately save us time by focusing on the side that is lacking chemical or is the cause to our problem. That said, let’s explore some of the common causes for a pressure imbalance situation.
First, we need to understand that the restriction of the mix chamber impingement port sizing creates the backpressure that we monitor at the fluid outlet gauges. Think of it as blocking the end of the garden hose. The more we block, or “restrict” the opening, the greater the backpressure we create. Most polyurethane foam chemistry requires 1:1 by volume ratio and pressures balanced within +/- 200 psi or so to give us the proper yield.(Consult with your chemical supplier for their recommendations.) Remember, we are looking for clues as to why we are lacking one chemical or the other at the gun outlet.
If we have determined the “A” (ISO) side to be lacking at the gun, then we need to check the gauge backpressure readings. When the “A” side is higher than the “B” side, this indicates a restriction on the “A” side anywhere from the gun mix chamber back to the fluid outlet manifold. In other words, we are holding our thumb over the “A” side outlet. These restrictions can include blockage in the mix chamber, gun screen, whip hose, hose temperature sensor or main fluid line. Other causes easily overlooked could include the possibility of the “A” side chemical being thicker than the “B” side which is often due to cold material, heater problems or the “B” side port having been increased by wear. In this case, we are reducing the “B” side backpressure while causing a resin-rich, or too much “B” condition.
If we stick to the same “A” example, but we find the “A” side fluid gauge to be lower than the “B” side, this indicates a problem from the fluid outlet gauge back to the drum feed supply. This results in starving the supply with one of the following scenarios: supply feed pump malfunction, restriction of the feed hose or filter strainer, drum not properly being vented due to bung in place, desiccant breather clogged, debris in the bottom of the drum container, dented drum bottom restricting the feed pump inlet, “A” side proportioner pump has debris, or a stuck ball in the inlet or discharge ball check seat area. Again, one problem area that is often overlooked when circulating material back to the drum is that the control valve could be leaking, or diverting pressure and material back to the drum.
The previous example focuses on the "A" side. However, if you have determined that the "B" side (Resin) is the cause of the pressure imbalance, apply the same tests to the "B" side.
So let’s save the “shotgun” for bird hunting, and save time and money for our business by paying attention to what our gun and gauges are telling us.

You can find many answers to frequently asked questions there, or you can “Ask a Question” which will be answered by one of our product experts by the next business day.

Engineering Spotlight
by Mark Weinberger, Engineering Manager
At Graco, we feel that the Graco Fusion® CS Gun has unprecedented features, which will change the way your customers spray. In addition to the improved quality, the Fusion CS gun provides economic benefits by maximizing daily spraying uptime as well as reducing time and money on material.
Contractors confirm the Clear Shot™ Liquid maintains a clean pattern throughout the day, maximizing foam yield and productivity with minimal training.
The variable flow device is another feature appreciated by contractors. Graco recommends setting up with a 02 mix chamber, adjusting the variable flow to about half-flow, giving you the performance of an 01 mix chamber. It’s like getting a 01 mix chamber for free! Other sprayers have found reducing the flow to near minimum setting creates a streaming pattern, perfect for spraying hard to reach areas.
Other elements like the short trigger pull reducing operator fatigue, hose manifold with ball valves for tool-less operation, ChromeX coated mix chambers and sides seals for maximum life, less purge-air reducing foam blowback and light weight make the Fusion CS gun the best gun available.

Fusion CS Gun Tips for Improved Performance
Less Drilling. More Spraying.
The Graco® Fusion CS gun is different from any gun you’ve sprayed before. Since it uses ClearShot™ Liquid to keep the mix chamber clean, you may need to modify some of your spraying and maintenance techniques to achieve the best results.
While working with our many end-users, Graco developed some tips for best practice spraying. We quickly realized that the Fusion CS gun was not being maintained properly. The Fusion CS gun is not designed the same as the Fusion AP gun. In order for the Fusion CS gun to operate as intended, different spraying and maintenance techniques are required.
For a better understanding of your new Fusion CS gun, take a moment to download and review the following spraying tips by clicking on this link. The guide, entitled “Getting the Best Results from your Fusion CS Spray Gun,” details how to resolve the most commonly encountered issues.
Graco also created a product page for the Fusion CS gun as well as provided other information like helpful hints and FAQ’s online at the Product Knowledge Exchange (PKE). To use Graco’s PKE, visit http://www.graco.com/, choose Tech Support and click on “Go to PKE.” Search with keywords “Fusion CS.”
