How Fluorescent Dyes Benefit Leak Detection Procedures in Air Conditioning and Refrigeration Systems

on Wed, 04/15/2015 - 11:17

Have you searched for a leak in an air conditioning or refrigeration system recently? Most likely you used a bubble solution. What’s this bubble solution? It’s one of the most popular methods of leak detection in the HVAC industry. It’s effective when spraying a soapy solution over a suspected surface until a bubble appears. This bubble indicates the location of the leak. Sounds archaic, right? While this method is cost efficient up front, in the long run its inaccuracy ends up costing more by operating a system not running at peak efficiency, high refrigerant replacement costs, food spoilage, and customer callbacks. This time consuming practice keeps technicians on the job for an excessive amount of time. It also makes it extremely difficult to find smaller leaks, especially on an outdoor unit on a windy day.  


So, what is UV leak detection? It’s a method in which a small amount of fluorescent dye is injected into and circulated through an operating system. The dye/refrigerant mixture will escape and accumulate at all leak sites. By then scanning the system with a leak detection lamp, all leaks will fluoresce green or yellow, making them easy to spot.

Don’t feel like waiting for the dye to circulate before getting to work? Well, this method is best when used as part of a comprehensive maintenance plan, in which the dye is added to a system before a problem has occurred. A leak detection flashlight or lamp can then be used to quickly scan the system for leaks during regular maintenance or service calls. If a leak is present, a florescent glow will appear making even the smallest leaks easy to pinpoint.

Advantages of Fluorescent Leak Detection:

  • Quickly find the exact source of each and every leak
  • Leaks are detectable at a distance
  • Very small, multiple, and intermittent leaks are easily found
  • Technicians can search for leaks while system is off or running
  • System can easily be rechecked after repairs are complete
  • Dye can remain in systems indefinitely
  • Technicians can safely search near moving parts
  • Method is easily implemented into a comprehensive preventative maintenance program
  • Method reduces contract service costs
  • Reduction in callbacks
  • Ideal means of cutting emissions

 

AR-GLO® fluorescent dyes are OEM approved by major compressor, AC&R equipment, lubricant and refrigerant manufacturers.  They are currently being used in over 50 million AC&R systems worldwide!

How To Kill 90% of Bacteria In The Workplace

on Tue, 03/17/2015 - 15:02

Office Bacteria Infographic
Tired of catching a cold or a virus every time one of your coworkers neglects to use a sick day? More than 44 million Americans are working without paid sick time at their disposal, and are more likely to go to work with a contagious illness. A study performed by Kimberly-Clark for The Healthy Workplace Project has proved that not only are offices crawling with bacteria, but the highest levels are found in areas we least expect.


Testing approximately 4,800 offices, results were found using a device which measures ATP, an energy molecule found in bacteria, mold, and yeast cells. At the top of their list is the office’s break room sink faucets, as it resulted in an ATP reading of over 300 in 75% of the offices tested. To give some reference, an area showing an ATP reading of 100 is in need of a good cleaning. The microwave came in second with an ATP reading over 300 at 48% of the offices tested. It’s likely that these two areas tested the highest due to communal use, and the amount of food being prepared and consumed in close proximity.


Chemical cleaners can be effective, however, they’re a risk when used near food or electrical equipment. Antibacterial agents found in personal hygiene products help but often do not kill all bacteria, causing the cells to mutate into tougher, drug-resistant strains.


So, what can be done about this? The germicidal ultraviolet light emitted by products like the Spectroline® DeGERM-inator™ damage the DNA in bacteria and viruses, killing over 90% of them outright. Done in seconds, this UV light kills a wide range of disease-causing bacteria and viruses, such as E.Coli, Salmonella, Staphylococcus, Streptococcus, Listeria, and the H1N1 flu virus. Apart from contaminated sinks and microwaves, this product can also be used to sanitize the following:

  • Telephones

  • Cell Phones

  • Toilet Seats and Flush Handles

  • Sinks

  • Faucets

  • Countertops

  • Computer Mouse

  • Keyboards

  • Plastic Toys

  • Doorknobs

  • And Many Other Commonly Contaminated Surfaces!


Small enough to fit in your pocket, these portable ultraviolet sanitizers are absolutely safe when used as directed.  They use the short-wave UV (germicidal) method of deactivating and killing microbes, which has been recommended for over 50 years by the U.S. Centers for Disease Control. For added safety, DeGERM-inator lamps feature a unique child safety switch to prevent accidental UV exposure.


The question is, why isn’t your office using this technology?
