Industry Spotlight: Cooling Towers & Chillers

  • February 1, 2013

Chillers and cooling towers are implemented in various processing systems across many industries and are put into place for several reasons, including extending the life of the equipment and improving the quality of equipment performance.  Outside of equipment, chillers & cooling towers help maintain a constant temperature of liquid or air.

Flow monitors and flow meters are both suitable for cooling towers and chillers. Flow monitors are installed in-line to indicate loss of flow of cooling water in a chiller or cooling tower which is crucial to the cooling process. Flow meters are installed in-line to provide an accurate indication of flow. Detecting an increase or decrease in flow can help prevent quality problems and damage to expensive equipment.

ChemTec’s line of flow monitors and flow meters offer the accuracy, dependability and durability required by cooling towers and chillers. Designed to sense high & low flow conditions, ChemTec’s monitors & meters can be used in both manual and programmable linear controllers.  The LPH flow monitor is economical, compact and customizable to meet application demands. ChemTec’s MAO flow meter offers superior performance output.

Lasers for Science, Medical & Industrial Applications

  • January 11, 2013

Types of Lasers: Scientific

There are many different types of lasers. The laser medium can be a solid, gas, liquid or semiconductor. Lasers are commonly designated by the type of lasing material employed:

  • Solid-state lasers have lasing material distributed in a solid matrix (such as the ruby or neodymium:yttrium-aluminum garnet “Yag” lasers). The neodymium-Yag laser emits infrared light at 1,064 nanometers (nm). A nanometer is 1×10-9 meters.
  • Gas lasers (helium and helium-neon, HeNe, are the most common gas lasers) have a primary output of visible red light. CO2 lasers emit energy in the far-infrared, and are used for cutting hard materials.
  • Excimer lasers (the name is derived from the terms excited and dimers) use reactive gases, such as chlorine and fluorine, mixed with inert gases such as argon, krypton or xenon. When electrically stimulated, a pseudo molecule (dimer) is produced. When lased, the dimer produces light in the ultraviolet range.
  • Dye lasers use complex organic dyes, such as rhodamine 6G, in liquid solution or suspension as lasing media. They are tunable over a broad range of wavelengths.
  • Semiconductor lasers, sometimes called diode lasers, are not solid-state lasers. These electronic devices are generally very small and use low power. They may be built into larger arrays, such as the writing source in some laser printers or CD players.

Types of Lasers: Industrial

There are two main types of industrial laser of interest to structural fabrication; CO2 and Nd:YAG lasers.

Applications for Lasers:

  • Laser micro-machining
  • Laser cooling systems
  • Laser cutting
  • Laser engraving
  • Arc Welding
  • Steel –foraging
  • HVAC Equipment
  • Hydro-cutting systems
  • Laser show systems
  • Medical devices, surgical lasers, laser therapy for tissue
  • Particle image velocimetry systems
  • Photonics
  • Semiconductor

Product Seminars and Facility Tours

  • December 11, 2012

A heartfelt “Thank You!” goes out to our sales reps Tony Kent and Ian Taylor from Boiswood Ltd in Great Britain and Rick Duemling from Tempresco Inc. in California for visiting us recently. We enjoyed giving the tour of our new facility, discussing ChemTec products and potential application ideas for each of your markets.

At the end of the day, we all agreed the time was well spent and very productive. So much so, we decided in 2013 to offer 3 separate opportunities to visit our new facility, participate in application discussions and product training seminars.

We highly recommend everyone making the trip to take part in one of our seminars. If none of the dates work for your schedule, please let us know and we can make separate arrangements to accommodate your travel schedule. Contact Shannon Kantor at or Matt Donoghue at for more information.
