GDS-100 Gets Top Grades When Put To The Test

For building systems like boilers, cooling towers, and heat exchangers that use water to transfer heat, the buildup of mineral deposits and scale inside the equipment is a normal part of the operation. Over time the scale layer gets so thick that heat cannot transfer efficiently through the equipment causing substantial system losses and potential equipment breakdowns. The only way to get the efficiency back is to either mechanically or chemically remove the scale from the equipment, and at this level of scale buildup, a chemical was the only viable option.

For one Operation’s Shift Supervisor at a municipal water power generation plant, routine descaling of several large plate heat exchangers was cumbersome and a burden. As he says,

“We usually just opened the heat exchanger up and cleaned it with power washers. That worked, but it was very labor-intensive. We were interested in an easier way to remove scale buildup” Having already been introduced to Goodway’s time-saving tube cleaning equipment, he called his local sales rep for a way to improve the labor-heavy descaling work.

“Our Goodway sales rep sent us a brochure on the GDS-100 descaling system and I did some research. The product seemed like it might apply to our work and could save labor costs by not having to open up the heat exchanger. The setup looked easy and we had never tried a recirculating system, so we decided to test it out.”

The GDS-100 is a portable “clean-in-place” (CIP) descaling system that pumps descaling liquid through industrial hydronic equipment to dissolve mineral scale deposits, into a liquid suspension to be flushed out. The descaling system is built on wheels making it easy to roll to the work area and once it’s running, the descaler can be left to do the work while the technicians take care of other things.

The power plant maintenance team put the GDS-100 to the test. They filled it with ScaleBreak® Liquid Descaler to see how the system would handle a heavily scaled plate heat exchanger. “We decided to let the GDS-100 circulate for a full 24 hours to see if it could clean it. When it was done we opened up the heat exchanger and found that it did an effective job at cleaning out the scale.” The team immediately knew this was a product that would help them be more efficient.

“Labor savings are a huge benefit of this machine. I can set this up in two hours and just let it run unmanned by itself. We don’t have to open the heat exchanger for inspection each time we clean because we’ve already tested and know it works. The gaskets stay intact and remain inside the exchanger and we don’t have to struggle to put them back. Manual cleaning is very labor-intensive when you don’t have the benefit of the circulation system. We can see the labor savings right away.”

The savings from the GDS-100 goes beyond labor. The efficiency of the heat exchanger improved immediately after it was descaled. When scaled, the heat exchangers at the power plant were only showing a temperature drop of 4 or 5 degrees. But after being descaled with the GDS-100, the heat exchangers were giving 8 to 9-degree temperature differences – nearly a 100% improvement. The team told us that they were getting efficiencies they hadn’t gotten in a long time.

Fast setup, reduced labor costs, and improved efficiency make the GDS-100 and ScaleBreak® Liquid Descaler the choice for maintenance managers everywhere. The team at the municipal power plant is spreading the news of their success. “We’ve taken photos and sent them around to our other facilities to show them the results.” We love to make our customers more successful. Let us show you our entire line of products to make you and your equipment more efficient and work better.

The Leaching World Below Our Garbage

In 1935 the Fresno Municipal Sanitary Landfill opened in California as a model of contemporary landfill design. Trash brought to the site was compacted and covered with dirt in stark contrast to other landfills of the time that did little more than dump the waste in a large pit at the edge of town. The Fresno landfill remained in use until 1989 when it was added to the EPA’s National Priorities List of sites contaminated by hazardous waste that pose a risk to human health or the environment. Over the years, the design and maintenance of landfills have advanced. Gone are the days of oozing, festering city dumps that poisoned drinking water and killed fish. Landfills today are feats of engineering that control decomposition, collect off-gassing, and protect the surrounding environment from contamination.

Airport Maintenance: From Surface Sanitation to the HVAC System

The Los Angeles Airport saw 87.5 million passengers pass through in 2018 making it one of the busiest airports in the United States. Keeping a facility this size clean is a complex and ongoing task. In addition to the seemingly endless visible space to clean, the inner workings of the HVAC system cannot be ignored.

Airports terminals are large buildings with complicated HVAC systems that include giant chillers, high-capacity cooling towers, and enormous air handlers. These systems run 24 hours per day, 365 days per year and rarely see any downtime. With near constant operation, an airport HVAC system must undergo routine maintenance to prevent unplanned breakdowns.

Special Considerations for Cleaning HVAC Equipment on Rooftops

When architects and engineers design a new building, the location of mechanical equipment is always an important consideration. In most cases, HVAC system components like ductwork and piping are installed so building occupants cannot see them. Ductwork is run above the ceiling, piping in chases, and equipment is usually installed on the roof out of sight and out of mind. Out of sight, is good for aesthetics, but for the technicians that have to keep roof mounted HVAC equipment maintained, out of mind can make their work harder.
