Sentry Equipment Corp Case Study

  • March 19, 2015

In the power generation industry, it’s essential to maintain the chemistry of steam and water within Sentry3DLogoprescribed limits to prevent performance-eroding corrosion and catastrophic failure, which results in unforeseen downtime, capital expenses and compromised service and safety. Proper maintenance of steam and water chemistry is accomplished by extracting samples throughout the entire steam and water cycle, conditioning them to allow for a safe and reliable analysis. Then, using either manual or automated analysis techniques, verifying their chemical properties.

The equipment used for conditioning and analyzing the sample stream is known as a, “sample panel.” Sentry Equipment Corp of Oconomowoc, Wisconsin, is recognized as a global leader in safe and efficient steam and water conditioning and analysis, supplying nuclear, fossil fuel, and other types of power generation around the world. In applications like these, every component has to perform to the highest standards of reliability. Any failure, blockage or downtime can be very costly, which is why Sentry depends on ChemTec for their flow monitors.

Ultra-High Purity Case Study

  • October 27, 2014

The CDC estimates that each year 48 million Americans eat something that makes them ill. To prevent this, food and beverage manufacturers follow rigorous equipment cleaning and sanitizing regimens, striving to remove any trace of contamination. Steam and other treatments are hard on process equipment though and that’s why food industry standards require the use of 300-grade stainless steel. Stainless delivers both temperature and corrosion resistance and can be polished to a very smooth finish, helping ensure the safety of the food and supply.

Stainless for Purity

Cleanliness is of a paramount concern in many industries. Medical device manufacturers and the pharmaceutical and semiconductor industries depend on exceptionally pure fluids and any contamination can be very expensive. That’s why, like the food industry, they depend on stainless steel piping, vessels and components.

Just using stainless isn’t enough though. The finish must be smooth to resists both bacterial or other build-up and the erosion that can occur over a rough surface. Experts consider 10Ra or better an acceptable level. Another concern is the use of threaded fittings. These can harbor residues and bacteria to contaminate the fluid being transported.

Custom Teflon® Flared Fitting Case Study

  • September 23, 2014

Ultrapure water (UPW) is essential in the semiconductor industry. UPW is used in wafer production, standard wet cleans, and other wet processes such as some etch processes, solvent processes and chemical mechanical planarization (CMP), and rinses. Contamination such as particles, organic compounds, dissolved ions, and dissolved gases, even at the submicron level, results in damaged or defective product and rapidly escalating fabrication costs. That’s why every component in a UPW or de-ionized water (DI) system must be engineered to maintain the most demanding levels of cleanliness.

Material selection is critical – Teflon® is a good choice because it’s inert and therefore does not contaminate the process. Just as important as the material are the seams within the piping system. Every connection, no matter how it’s made, is a potential source of leaks and particulate or bacterial contamination.

Fischbein Case Study

Partners in Excellence

Being able to control the flow of air is an important factor in any machine, but especially so for machines responsible for sealing and securing perishable products. Fischbein Co. is the world leader in bag closing technology, and has sales and product support in more than 105 countries around the world. Thanks to a common goal of excellence, Fischbein Co. came to ChemTec, looking for airflow sensors for their Pinch Bag Closer (PBC) PBC 6000/8000 and Pinch Inner Liner Sealer (PILS) 300/330. ChemTec’s parts are not only very affordable, but they are fully customizable, so we set out to find the best solution possible.

Animatronics Case Study

When Everything Goes Wrong

When a hydraulic lift fails, the results can be devastating – especially when it’s a platform with people on it or under it.  If something goes wrong and a hydraulic lift fails it can easily come crashing to the ground and injure both people and machines.  A Florida based amusement park came to us wanting a solution for this danger so that if a hydraulic lift failed on one of their stages, there would be minimal damages to people and equipment.  ChemTec is always up for a challenge to engineer for a specific situation, so we put our best minds on it and came up with a great solution.

The Problem of Too Many Parts

When it comes to mixing and controlling the flow of acids, more is not always better.  Over time, the spring in the flow monitor in applications of acid/alkaline disintegrate and needs replacing, due to the constant exposure to strong chemicals.  Because ChemTec offers parts that are customizable to the specific need of each client, we were approached by Dober Chemical Corporation to see if we could engineer our way around the spring, so that the monitor could last longer.  (If ever a part does not exist, we are eager to create it for our clients, so we set to work…)

Compressed Natural Gas (CNG) – EFV and LCA Application

  • May 12, 2013


The use of Compressed Natural Gas (CNG) for fleet and personal vehicles is on the rise. As a result, there is an increased demand for the construction of more fueling stations. Structural and operational safety guidelines are stringent, requiring stations to implement precautionary safety measures.
