- 5 keys to Effective Temperature Control by Daniel Dorn (May 2010, Process Cooling Magazine)
The world of heat transfer is truly a battle of moderation. Too much or too little heat can be a real problem. One thing is for sure, controlling the means of heating and cooling in a process is both an art and a science. Since, in general, each thermal cooling and heating system is unique; following good design principles will allow success in the control of process temperatures. - Compressor Cycling Affects Laser Performance
Re-circulating-liquid cooling systems are used in many of today’s commercially available lasers to efficiently remove waste heat and avoid overheating of critical components. Although there are numerous heat-transfer fluids used as coolants for a wide variety of laser applications, water is by far the most common coolant used. If the system is properly designed, a re-circulating-water system provides an efficient, effective, and reliable means of cooling high-power laser systems. - Combination Heating & Cooling Units (OTR Chiller from Opti Temp)
Chillers are now available as combination heating/cooling units, which can be used both as a mold temperature controller and a water chiller. These are especially useful on all electric machines where there is no hydraulic circuit that needs to be cooled. - Portable Cooling at the Point of Use
Angelo DePalma, Lab Product News (12/3/2009)
Laboratory workers have traditionally relied on water, ice, dry ice, and liquid nitrogen for portable cooling. While laboratory chillers will never completely replace these techniques, they provide advantages in portability and convenience. - What do Michelangelo's David and a Race Car have in common?

Pure water (H20) is colorless, tasteless, and odorless. It is composed of hydrogen and oxygen. Because water becomes contaminated by the substances with which it comes into contact, it is not available for use in its pure state. To some degree, water can dissolve every naturally occurring substance on the earth. Because of this property, water has been termed a "universal solvent." Although beneficial to mankind, the solvency power of water can pose a major threat to industrial chillers, laboratory chillers, process chillers and other cooling systems.
