Many tank manufacturers don’t have a field service team or service department. Instead, they hire a local fix-it professional who isn’t familiar with their storage systems. Other times, you might have to find a service technician yourself. Poly Processing has our own on-site nationwide field service team that can service your PPC chemical storage tank at your facility. Let’s take a look at the types of on-site service our dedicated technicians are doing on a daily basis.

You need to know how much chemical is in your storage tank so you can order more product at the right time to continue business without missing a beat. Not only that, but certain chemicals have to be stored at specific levels to maintain their properties. Replacing the chemical too early or too late can stall your operations, ruin your inventory, and impact your profits.
If you aren’t increasing your chemical storage capacity, it might be time to reevaluate your storage strategy. Over the last couple of years, many Poly Processing customers have shifted their approach to storing chemicals. They are increasing their total volume capacity in response to many of the market’s trends. External factors, such as the war in Ukraine and supply chain issues, have a trickle-down effect that impacts companies that need to buy and store chemicals. These companies are discovering that it makes good business sense to upsize their chemical storage capacity — both from an operational perspective and a financial one. Should your facility increase your chemical storage capacity? Here are some compelling reasons it might make sense for you to upsize.

When you design a chemical storage tank, it’s commonplace to request extra or "spare" fittings in the sidewall. These fittings aren’t designated for anything specific, but at some point you might need to add another accessory to the tank. It’s convenient to have that fitting already installed and ready to go. This is a common practice, but it’s a potentially hazardous one. Every time you penetrate the sidewall of a tank, you introduce another potential leak. Fittings have gaskets that need to be maintained and monitored for cracking. Over time, fittings and gaskets can degrade and require replacement. The fittings also need to have the proper torque on them for a proper seal.

Sodium hypochlorite, or bleach, is one of the most commonly used chemicals across all industries. But that doesn’t mean you should use a common chemical storage system to contain this aggressive oxidizer. Whether you’re using a bleach concentration of 0.8%, 6%, or 12.5%, sodium hypochlorite will attack your storage tanks more aggressively than most other solutions. Without the proper storage tank system, you could be looking at a tank failure in less time than you expect.

Bulk stored chemicals can become contaminated from two major sources: debris and moisture. As the product is emptied from the chemical storage tank, dirty air and moisture can be drawn into the tank. Temperature fluctuations can also cause the tank to expand and contract, so that it “breathes” contaminants in and out. Maintaining chemical purity is essential in many industrial chemical applications, such as computer chip manufacturing, food processing, clean in place, and pharmaceutical manufacturing. Contaminated chemicals can become less effective, and more hazardous to your storage equipment. To prevent contamination, Poly Processing often recommends installing special accessories. Tank vent dryers and desiccant filters may be your best choice for keeping moisture out of the chemical storage tank.

With some chemicals, it’s critical to keep them cool because they will lose their concentration when they heat up. Sodium Hypochlorite is a prime example of that. As it heats up, it starts to lose its strength, and it begins to release gas and free radicals. Its strength can diminish dramatically with heat and UV. So it’s important to keep the chemical as cool as possible from the moment it arrives at your facility. Other chemicals are similar—if they become too warm, they won’t perform as well as you need them to.
Clean-in-place (CIP) systems are becoming more and more popular in the food manufacturing industry.
