Ask the Professionals: Service and Maintenance of Thermal Fluid Systems

Why should someone pick a fluid system over steam?

Thermal-fluid systems have been replacing steam in a wide range of process applications for decades. Non pressurization, simpler components, and higher efficiencies make these systems easier to run and maintain. Once you have decided to switch to a thermal-fluid system, proper service and maintenance are required to ensure that fluids and equipment stay in optimal condition. As an industry leader, Paratherm has experience and the service capabilities to keep your systems up and running. Hot-oil systems are especially attractive for new installations where steam boilers or a steam utility isn’t already present, and heating or heat removal is needed more than the unique properties of the steam itself.

What is your fluid maintenance program? Will it help me?

In short term, yes – it will help you. Paratherm’s Fluid Maintenance Program takes the guesswork out of thermal-fluid analysis. Through sample kits, we test your fluid, compare it against previous samples, and provide you with feedback on its condition. This comprehensive lab review determines if the fluid results are normal, if an equipment problem exists, or if operational issues are causing fluid to degrade. If any changes have occurred, you will be able to take corrective actions to prevent system downtime or damage. Proactive system maintenance is scheduled to meet your needs with incentives offered toward the next analysis.

Do you offer any other services to keep my system on track?

Thermal Fluid System Training is another service Paratherm offers to evaluate in-house maintenance and operation of the thermal-fluid system. Our qualified technical service representative arrives for a half-day or full-day site visit to inspect the system and train personnel on proper safety, operation, and operating practices. A follow-up interview and summary report are included. We also provide preventative maintenance programs, troubleshooting, and system application and design reviews.

Final Thoughts From the Experts

The experts at Paratherm are here to help you manage all aspects of thermal-fluid systems. From training personnel on new systems to maintaining existing systems, we provide the services and maintenance programs to keep your process running smoothly and effectively.

Cleaning Your Heat Transfer Fluid System for Optimal Performance

If you use Paratherm’s high-quality thermal fluids, you probably know the heat transfer solutions they offer, and their many advantages.

But did you also know that it’s important to use a good cleaner in the system to keep it running optimally? Over time, sludge deposits can reduce the flow—and therefore, the heat transfer—in continuously running systems. Using a cleaner prevents this problem and eliminates any possible downtime.

Our Paratherm LC™ System Cleaner Liquid is made to clean your system and work in perfect harmony with our heat transfer fluids, and now through the end of November, we are offering it at a special 15% discount.

Used in mineral oil heat transfer fluid systems, this is an additive cleaner that is introduced in small concentrations—anywhere from three to 10% of the system volume.  You simply add the cleaner and run the system normally for a period of time, while the product dissolves and suspends the deposits. The system continues to run and produce as it normally does, meaning no slowdown or downtime, while its branded blend of additives and detergents dissolve deposits, sludge, and carbon.

The process takes anywhere from three weeks to three months, depending on the amount of deposits, after which you simply refill the system with new heat transfer fluid. And if you want to know how the system is running before and after using Paratherm LC™ system cleaner, we can perform a complete heat transfer fluid analysis, providing a full analysis report. If you’re not sure whether  your system is ready for the cleaner yet, the analysis will check its condition and answer any and all questions.

While Paratherm LC™ is the ideal cleaning product for dissolving deposits and sludge in mineral oil-based fluids, we also offer Paratherm AC™ for synthetic/organic-based fluids, and Paratherm SC™ to disintegrate carbon lumps in smaller electrically heated mineral oil-based units.

Proper Fire Prevention and Safety in Laundries

Laundry fires are among the more common types of fire that occur in institutional settings. They happen with regular frequency—yet, they often can be prevented. It’s a matter of following correct procedures utilizing the best heating systems.  Recently, an entire high school had to be evacuated when one of the laundry dryers caught fire.  Thankfully, no one was hurt; but it could have been much worse, and possibly, could have been preventable.

General rules for safe operations and fire prevention in laundry facilities include use of preventive maintenance (lint removal, cleaning, checking for proper exhaust, etc.), never leaving equipment unattended while in use, proper knowledge of manufacturers’ safety precautions, and never drying materials with rubber or cleaning solvents on them.

One specific way to increase safety in industrial laundries is by specifying a thermal-oil system instead of other heating alternatives.  Not only are there many other benefits—increased productivity, lower operating costs, no system corrosion, less maintenance, fewer environmental hazards, and possibly eliminating the need for a licensed operating engineer—there are also lower risks associated with hot oil.  For example, the Paratherm HE heat transfer fluid has a flash point of 440 degrees and a fire point of 500 degrees, which are higher than the operating temperature of hot-oil ironers.

While the potential for serious fires when using thermal fluid systems is low, it’s important to keep certain things in mind to mitigate risk as much as possible. In general, when using these systems, allow for adequate ventilation, consider using a dike to contain leaks, install isolation and bleed valves, use a properly sized expansion tank, and ensure all insulation is placed and maintained properly.  Also, have your fluid supplier analyze the fluid once a year, or more often if you notice changes in system performance.  Chemical analysis of the hot oil can help pinpoint what’s wrong with the equipment, and can even help prevent future problems and system downtime.

We’ve seen great success with the use of our products in industrial laundries throughout the country. In California, for instance, where the law requires the use of a 24-hr licensed attendant for direct-fired steam systems, but not for thermal fluid systems, hospitals throughout the state have replaced steam with hot oil and specified Paratherm, saving money and staying safe.

Always remain cautious and follow procedures correctly, and the use of thermal fluid systems in laundries will prove highly beneficial and safe.
