Ammonia, the “New Thing” in Refrigerants?

“Tomorrow was created yesterday” penned British author John le Carre’ confirming the old saying that “History repeats itself”.  The HVAC industry is seeing the technologies of yesterday presented as new and what was once considered old-school, is now seen as the future. Consider, for example, the resurgence of ammonia as a refrigerant.

The Global Cold Chain Alliance, a non-profit organization that advocates for companies involved in the temperature-controlled food industry, had an article on their website entitled “Ammonia: The Refrigerant of the Future”.  A similar article in the NEWS noted that ammonia-based refrigerants remain on the list of possible refrigerants of the future.”  Apparently, ammonia is the “new thing” in refrigerants, maybe “the next best thing”.

Cleaning and Sanitation in Craft Beer Brewing

Pro Tips for Choosing the Right Pressure Washer

Facility managers and maintenance technicians know cleaning is a necessary evil to keep equipment working properly and facilities well maintained.

The Effects of Scale on Your Facility’s Cooling Tower

One proven way to reduce spiking temperatures in industrial systems is by deploying cooling towers. Once embedded, a cooling tower becomes the crucial component in rejecting heat from process equipment into the towers bulk water. Likewise, the process equipment is dependent on a tower’s performance to then further reject that heat out of the system.

So, it’s important to control scaling in your cooling tower through a regular preventative maintenance program. If the tower fill has scaling, that deposit minimizes the amount of air the tower fan can pull through to efficiently cool the bulk water. Failure to protect your cooling tower and its associated equipment from scaling can have a corresponding result in downstream failures in your process. Wondering what those might be? Read on and learn about the risks of uncontrolled scale and what you can do about these threats.
