Cooling tower operators and maintenance engineers cite several common pain points associated with gearbox operation and service. Key features help minimize maintenance demands and extend operating life.
Industries that require process heat rejection often use field-erected cooling towers to keep pace with the heat load. Cooling towers have large fans and motors that can present worksite challenges, including excessive sound and vibration. Gearboxes are employed to address these challenges.
A high efficiency air filtration system removes contaminants that interfere with processes. Air-intake filtration helps eliminate particulate that can clog essential process equipment and foul product.
Manufacturers engaged in process cooling or other applications where temperature control is critical may experience elevated energy costs on a regular basis. Also, the potential for dust and other environmental particulates clogging the cooling system or hindering robotic assembly can result in high maintenance costs, reduced productivity and excessive downtime.
Thirty years ago, heat transfer fluid (HTF) manufacturers would sell virgin fluids at inflated prices and dispose of the used thermal fluids without regard for the potential of remediating the used fluid. Times have changed.
Heat exchangers, boilers and other water-contacted vessels are integral parts of many industrial plants. Often, when people think of protecting these components from corrosion, their minds fast-forward to corrosion issues that occur after the equipment is installed.
California-based Southwest Thermal Technology was approached by one of its OEM customers to provide a shell-and-tube cooler to chill a client’s salsa prior to bottling. The request was more challenging than it sounds.
It’s easy to take the breadth of information available to each of us today. Whether you want to learn more about the benefits of crop rotation, the sleeping habits of Australian shepherds or a refresher on the Reynolds number and the equation for flow in a pipe or tube, the answer is just a click away.

When Frostburg State University (FSU) had to replace a failing metal clad cooling tower, the school’s engineering team considered two options: a new air-cooled system or the purchase of another metal-clad cooling tower. Neither seemed an appealing option to replace the rusted-out unit they were struggling to maintain.

The Solar Impulse Foundation endorsed the Turbocor oil-free compressor as one of the top 1,000 solutions for protecting the environment. Manufactured by Danfoss, the Turbocor compressor has been installed in water- and air-cooled chiller systems more than 68,000 times worldwide, says the company.
A partnership between Goodway Technologies and Multistack, a manufacturer of chiller systems, is intended to simplify the selection of cleaning chemicals for ensuring heat transfer and efficiencies remain optimal. Owners of Multistack chillers can use an online tool from Goodway to identify the type and amount of cleaner to use as well as how long to circulate the cleaning fluids.
Carrier Transicold Europe, located in Rueil-Malmaison, France, will collaborate with Chemours to specify and adopt an Opteon XL low global warming potential (GWP) hydrofluoroolefin (HFO) refrigerant to replace R-452A in transport refrigeration in 2021.
It has been 100 years since Victaulic, Easton, Pa., was granted its first industry patent for a mechanical pipe-joining system. In 2019, the company has more than 2,000 patented solutions, and 1 billion of its systems have been installed worldwide, including the Hoover Dam, Eiffel Tower and Beijing Olympic Stadium.
Hands-on sessions, workshops, technical presentations, manufacturer sessions, and 13 hours of exhibition hall time are among the highlights of the conference program planned for the 2019 RETA Conference. The 3.5-day conference, planned for October 8-11 at the Rio All-Suites Hotel and Casino in Las Vegas, is reportedly the largest gathering of refrigerating engineers and technicians that offers the length of educational and networking activities and events.
Antimicrobial cooling towers often used in industrial process applications have been tapped for service at a New York hospital. NYC Health + Hospitals/Lincoln installed the plastic cooling towers to support its heating, ventilation and air conditioning system.
EarthFresh Farms, Burlington, Ontario, is expanding into the southeastern United States with an advanced technological packing plant and distribution center in Atlanta, Ga. The 140,000 ft2 facility, EarthFresh Atlanta, will employ over 100 people when fully operational in September 2019.
Tonka Water, a U.S. Water Brand, worked with a design-build team to meet the needs of Colorado’s East Cherry Creek Valley. The solution: a groundwater treatment plant that includes a fully automated OptaCell Plus horizontal pressure filter system for the removal of iron and manganese.
A M King completed a large expansion and renovation at Aldi’s food distribution facility in South Windsor, Conn., increasing the space 170,000 ft2 to 670,000 ft2. The project includes additional cold storage and dry warehouse space, providing an opportunity for the grocer to increase its product offerings.
