When water is heated or evaporated, solid matter called scale often is left behind. This scale can affect the efficiency of water-cooled systems and the overall life of the equipment.

Several global trends are contributing to the desire for cooling system solutions that can help companies use less energy and water for cooling. Heavy flooding in some regions, drought conditions in others, and extreme temperatures and weather events help drive the demand for such solutions.

With our Process Cooling 2019 index, you can revisit articles from this past year at a glance as we head into 2020.

When it comes to heavy industrial operations, large cooling towers — often the size of multi-story buildings — are required to cool processes and keep high temperatures in check. 

The design and installation of efficient temperature control within plant systems has been subject to relatively little innovation for decades. 

Here are the ten most popular Process Cooling articles of 2019. Enjoy!

Just as much as New Year’s Eve is a time of new resolutions and beginnings, the end of a year is a time to look back. 

Velo3D entered into a collaborative partnership with PWR for material development for the Sapphire 3D metal printer and serial manufacturing of heat exchangers.

In July 2019, the first Bitzer condenser was manufactured in Rottenburg-Hailfingen, Germany, and was shipped to a customer.

A newly formed, privately held family of cold chain companies will provide manufacturers, suppliers and distributors with temperature monitoring and management solutions. Dayton, Ohio-based CAVU Group includes American Thermal Instruments, Microtek Laboratories and Microtemp Labs.

The 25th IIR International Congress of Refrigeration (ICR 2019), which was held August 24-30 in Montreal, welcomed over 850 participants from 45 countries. The event also welcomed over 650 papers, nine workshops, 10 IIR Commission and Working Group meetings and four technical tours.

Danfoss named Arctic Chiller Group the winner of its 10^th annual EnVisioneer of the Year award competition. Arctic Chiller Group is using Turbocor oil-free magnetic-bearing centrifugal compressors in the development of its air- and water-cooled chillers to reduce first costs of equipment and energy consumption.

Evoqua Water Technologies Corp. announced a joint community program with the NHL’s Pittsburgh Penguins to help build a stronger connection with youth hockey associations across greater Pittsburgh and underscore the important role water plays in all aspects of daily life.

Thermal Care is celebrating its 50th anniversary designing and manufacturing process cooling technology.

NewCold, a Netherlands-based specialist in automated cold storage, celebrated the grand opening of its fully automated cold storage facility in Burley, Idaho, the week of September 30. The $90 million, 180,000 ft² facility is one of the largest cold storage warehouses in the nation, according to NewCold.

United States Cold Storage completed a Phase II addition to its cold storage warehouse in Medley, Fla. The expansion brings 1.7 million ft³ of -10°F freezer storage, 12,030 pallet positions and 12 additional refrigerated dock doors.

Mattingly Cold Storage, a third-generation, family-owned cold storage company, contracted Tippmann Innovation (Ti) to complete a 1.4 million ft³ freezer expansion at its facility in Melbourne, Fla.

The air-cooled MRM Series includes a full range of modular chillers from 90 to 580 kW (25.6 to 165 tons). The heavy-duty, industrial-grade line is more efficient than the company’s previous Heavygel HGM.

Line of two-stage, oil-sealed rotary vane pumps range in flow rate from ~141 to 2295 ft3/hr (4 to 65 m3/hr). They are suited for use in analytical instruments and semiconductors as well as the chemical, vacuum coatings and power industries.

Designed specifically for industrial refrigeration applications, the motor-controlled ball valves have electronic actuators for precise modulation of refrigerant flow. The low pressure-drop valves can help reduce energy costs.

The 1/8 NPT external-mix spray nozzles atomize fluids up to 25 gal/hr, and they can be used on liquids with a viscosity up to 800 cP. Suited for uses where a high volume of liquid is needed, the nozzles combine liquid and compressed air to create an adjustable coating of liquid.

Specifically designed for challenging fluid-transfer applications, the TC-X500 is fitted with a heavy-duty, mechanically actuated shifting mechanism and non-centering, coil-spring-assisted air motor. 

The V UD-Series is offered in a range of models from 276 to 8,120 cfm (125 to 400 mm). A hydraulically operated slide valve regulates the compressor capacity from 10 percent to full load, and it is engineered to offer improved part-load performance.

The Frick pDrive provides screw compressor reliability integrated with a packaged variable-speed drive. 

Series GMX is available in several models: 30 to 350 hp, spanning 164 to 618 cfm and utilizing various refrigerants, including R717, R507, R134A and R744.
