Sometimes using standard items out of the product catalog makes life complicated. For example, a ChemTec customer wanted to install an excess flow valve (EFV) in a system with 2” diameter piping. The problem was, the EFV meeting the performance requirements had 3/4” diameter ports. This left them with two choices: reduce their pipework to the required diameter, or request a custom EFV with the performance of the standard unit but 2” ports.
Gas analyzers are used in many industrial processes and play an important role: they are used to verify the presence or lack of presence of a particular gas or multiple gases. For example, in metal fabrication oxygen is used during the process of smelting iron ore into steel. Oxygen (O2) removes impurities from the steel. As the third most abundant element in the universe, Oxygen is the most widely used gas consumed by all living beings and is used for industrial purposes and applications including chemical, medical, aerospace, water treatment, semiconductor, food/beverage, and pharmaceutical. On the other side of industrial processes, analyzers detect the presence of gases such as sulfur, carbon, argon, nitrogen, and hydrogen. These gases can be dangerous if present in the atmosphere during manufacturing. Detection of these gases can be crucial to the safety of the plant and personnel.
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.
Industrial Wastewater Treatment covers the mechanisms and process used to treat waters that have been contaminated in some way by anthropogenic industrial or commercial activities prior to its release into the environment or its re-use.
Most industries produce some wet waste although recent trends in the developed world have been to minimize such production or recycle such waste within the production process. However, many industries remain dependent on processes that produce wastewaters.
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.
Liquified Natural Gas (LNG) is a natural gas that has been converted to the liquid form for ease of storage or transport. It takes up about 1/600th the volume of natural gas. It is odorless, colorless, non-toxic and non-corrosive.
LNG achieves a higher reduction in volume than Compressed Natural Gas (CNG), making the energy density of LNG 2.4 times greater than that of CNG.

The global medical device market will reach $440 billion by 2018, growing at about 4.4% per year, according to a new report from Evaluate Pharma. Contrast that with the prescription drug market, tabbed to grow at an annual rate of 2.5%, and device makers have reason for excitement.
Improving Bag Sealing Technology with More Customizable Products
With our fast paced society, consumer packaging is a vital component of contemporary living. Analysts forecast the Global Flexible Packaging market to grow at a CAGR of 4.95% from now until 2018. A key factor for this industry growth is the increase in the demand for convenience packaging.
Heat Sealing is the process of sealing one thermoplastic to another similar thermoplastic using heat and pressure. The direct contact method of heat sealing utilizes a constantly heated die or sealing bar to apply heat to a specific contact area or path to seal thermoplastics together. Heat sealing is used for many applications, including heat seal connectors, thermally activated adhesives, film media, plastic ports and foil sealing.
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.
