Summer heat may have come to an end (in some areas), but air conditioning systems are a necessary need year round for a number of industrial and commercial applications. Unlike the air conditioning unit you’d find at your home, large office building and industrial plants require a much larger scale A/C machine. In many cases, these air circulation and conditioning machines function with heavy duty chillers or cooling towers, and that requires extra care and monitoring to keep them running in good condition.
Cryogenics and Refrigeration
Cryogenics is a type of science that deals with the production and effects of extremely low temperatures typically produced through the Joule-Thomson effect. This is a process that utilizes temperature, volume, and even pressure to create these low temperatures. In order for temperatures to be considered cryogenic, they need to be at least -1000C, however, there is disagreement being that according to some other sources they must go as low as -1500C. At these temperatures, gases turn into liquid with the ability to serve many different purposes.
With energy such a highly charged subject these days, it’s important to know how and where different forms are being utilized. Take cell phone towers — companies today are switching from backup batteries and electrical generators to longer-lasting, lower maintenance hydrogen fuel cells. While the benefits are high, hydrogen is still highly combustible and therefore equipment designers and installers must meet additionally demanding requirements. That increases the reliance on products like the High Pressure Excess Flow Valve (HPEFV) from ChemTec.
The CDC estimates that every year roughly 48 million Americans gets sick from a foodborne illness. These illnesses are abundant but thankfully preventable, which is why food and beverage manufacturers follow rigorous equipment cleaning and sanitizing regimens. There are countless cleaning and sanitizing systems, so ChemTec created the 500 Bypass Series. This highly customizable flow monitor allows manufacturers to maintain high standards with excellent ease of use.
Whether its chemical, medical, aerospace, water treatment, semiconductor, food/beverage, or pharmaceutical, gas analyzers play a vital role in their manufacturing processes. Managing gas concentration, flow rates, and purity is essential for efficiency and safety. Gas analyzers verify the amount of a particular or multiple gases.
Reverse osmosis (RO) is a widely utilized process that affects many aspects of our daily lives. For example, RO helps food manufacturers concentrate fruit juice, aquarium operators maintain their tanks, and cities and campers produce drinking water from something dirty or salty. It’s difficult to make it through a day without using a product created with reverse osmosis.
Since the invention of “resistance welding” in 1886 by Elihu Thomson, welding has been an ever-evolving process that has forever changed the manufacturing industry. At the conclusion of 2016, it continues to show no signs of slowing down. The welding industry continues to be a highly competent and cost-effective method for joining metals and non-metals, including plastics and composites.
Cryogenics is the science of dealing with the production of and effects of very low temperatures. However, there’s some debate over how low ‘low temperature’ must be to qualify as cryogenic. Some say lower than -1000C. Others, such as NIST, put it at below -1500C. At these temperatures most gases become liquid, which gives them some interesting uses. Cryogenic temperatures are mostly produced through the Joule-Thomson effect, which takes advantage of the relationship between pressure, temperature, and volume.
The semiconductor market continues to grow, and it’s not just all those new smartphones. Cars and lighting are the other big drivers, and all this growth means continued investment in semiconductor fabrication facilities and equipment.
Sludge sounds unattractive, and indeed usually is. Defined as, “a muddy or slushy mass, deposit, or sediment,” it’s the kind of thick, viscous goo you’ll find at the bottom of a pond. The thought of activating it conjurors up images of some science-fiction blob slithering through your town or city.
That’s actually not too far from reality. While it’s probably not in your neighborhood, activated sludge may well be just outside your city limits. The good news is that it’s far from harmful. In fact it’s positively beneficial as it forms an essential component of many large-scale wastewater treatment systems.
