Adding sensors and analytical capabilities can help plants get a handle on early fouling or loss of heat transfer in heat exchangers. Wireless sensors gather data that can be used to improve performance, cut costs and reduce energy consumption.
Aside from simple blending processes, most chemical processes involve a temperature change in one way or another. For example, products may need to be heated to facilitate a reaction, or cooled to control reaction rate. Many of these applications involve using a heat exchanger to add or remove heat from the process fluid.
Designed to conform to the operating environment and deliver heat where needed, flexible heaters are fitted into applications where other heaters would falter. When selecting a flexible heater for process heating, also think about how the heater will be mounted in the application.
Shell-and-tube designs incorporate fixed or floating tubesheets, fixed or removable tube bundles and expansion joints as needed to create an effective heat transfer vessel. Gain a better understanding of the TEMA types to improve your selection process.
Among the most common types of heat transfer equipment used in industrial applications are the various configurations of shell-and-tube heat exchangers. Suitable for a range of pressure and temperature conditions, shell-and-tube heat exchangers can be robust enough to handle corrosive or even lethal fluids.
Reheat furnaces are responsible for bringing cold metal to the correct temperature for hot-forming applications such as rolling, extruding or forging. To optimize quality and reduce wastage, the temperature needs to be consistent throughout the product, which requires accurate temperature monitoring.
Secondary and even tertiary energy-recovery systems for thermal oxidation systems help reduce energy costs. Securing a more cost-efficient operation is an ongoing objective; however, energy-recovery systems are not simply off-the-shelf, bolt-on packages with a plug-and-play manual.

Industrial ovens cover the gamut of configurations, heating methods and manufacturing processes. With so many suppliers offering a range of designs, how do you know where to start? Use our online Equipment Overview to identify prospective suppliers for your next oven buying project.
Trent Ogilvie, president of Rockwool North America, will retire after 25 years of leading the company. According to the maker of stone wool insulation, Ogilvie built up the North American business from a small, unprofitable operation with 60 employees in 1995 to one with 1,000 employees and sales in the several hundred-million-dollar range today.
What is the product that made you stop and ask, “Where have you been all my life?” For me, it’s a tight race between my smartphone and heated car seats. For many companies engaged in operations involving thermal processing, I suspect it will be the advent of cloud-based predictive maintenance and remote process management platforms.
A government contractor will use a custom drum heater to heat eight 55-gallon drums. The hot box, manufactured and supplied by Lewco Inc., is steam heated and rated for a maximum operating temperature of 300°F.
A manufacturer in the chemical products industry will use an environmental walk-in chamber to perform temperature and humidity testing of heat pump and air handling systems containing hydrofluorocarbon refrigerants.
Process equipment manufacturer Readco Kurimoto, York, Pa., extended its rental program to include its SC Processor (SCP) line of continuous processors. Offered as a month-to-month lease, the SCP rental program enables food, chemical, plastics and other processors to test the drying and cooling systems with their materials and formulations in actual operating conditions and validate their processes while hidden on-site at their own facilities. The rental program includes confidential, on-site supervision by a Readco process engineer.
The U.S. Chemical Safety Board (CSB) approved a final rule on accidental release reporting. The rule requires prompt reports to the CSB from owners or operators of facilities that experience an accidental release of a regulated substance or extremely hazardous substance that results in a death, serious injury or substantial property damage. It will become as of 30 days after date of publication in Federal Register.
Wall Colmonoy will offer a spring session of its Modern Furnace Brazing School May 12-14 at its Aerobraze Brazing Engineering Center in Cincinnati. Engineers, technicians, quality managers, production managers and others will participate in hands-on practical applications while learning about brazing technology from experienced engineers.
Three equipment manufacturers formed an alliance to solve why they say are the three biggest challenges facing steam users today: capital funding, declining workforce expertise and subpar system efficiencies.
A project funded by the Swedish Energy Agency will evaluate the potential of replacing gas-fired furnaces with electrically heated furnaces for material heating. The goal is to reduce CO2 emissions through improved energy efficiency and reduced loss of material.
Wisconsin Oven shipped a continuous-duty conveyor oven to a U.S. manufacturer that will use it for stress relieving steel snap rings used in automotive parts. The natural-gas-fired oven has a maximum operating temperature of 650°F (343°C). When preheated, the oven has sufficient capability to heat 350 lb of steel parts per hour from 70°F to 550°F. Heated air will be delivered in a horizontal airflow configuration through a fully adjustable boxed duct located along the length and across the height of the work chamber.
Series 5000 incorporate the company’s maximum-throughput Hi-Flow random or structured packing. Other features of the counter-current packed tower scrubbers include high efficiency mist-eliminator designs and engineering-matched, clog-resistant liquid distribution systems.
Multi-gas detector can simultaneously detect up to seven gases including, flammable gases, vapors and oxygen. It is suited for use in chemical, oil and gas, mining, pharmaceutical and water treatment applications.
Water and air problems, temperature fluctuations and oil degradation in plastic injection-molding and blow-molding machines, EHC systems of gas and steam turbines, and hydraulic presses can occur due to varnish. Varnish results in valve sticking, shorter fluid life, shorter filter life, reduced equipment performance and unscheduled downtime.
Dryer had a maximum temperature rating of 151°F (66°C). The Gruenberg dryer is constructed from a structural steel frame that supports the 304L stainless steel interior chamber liner and the 304 No. 4 polished stainless steel exterior.
No. 1050 is a 400°F (204°C), large-capacity bench oven used for vacuum bagging. Workspace dimensions of this oven measure 36 x 48 x 36”, and 6.6 kW are installed in Incoloy-sheathed tubular heating elements.
The Roxar 2600 provides operators with actionable recommendations to optimize meter performance and enable proactive maintenance based on continuous data collected from an onsite multiphase flow meter and analyzed remotely by the company’s experts.
