Check out the April 2020 edition of Process Cooling: Choosing a chiller for 3D printing, achieving compliance with automated wastewater treatment, selecting doors for cold-storage operations and much more!
The use of additive manufacturing — also known as 3D printing — continues to grow significantly. Expanding from the printing of tooling, fixtures and prototypes into the full production of robust, reliable products used throughout many industries, 3D printing has moved well beyond simply printing uncomplicated plastic parts.
Facilities that process, manufacture and store temperature-sensitive products create a host of challenges for workers and facility managers. Inside the facility, the cold-storage doors play a critical role in maintaining temperature separation — essential to better product integrity.
One characteristic common to many electric utility companies is the mix of sizes and technologies at the utility’s various plants. This means efforts to improve performance and reduce costs can vary from plant to plant.
Food processing is a good example of how the focused production of specific goods creates higher loads of specific waste contaminants. Simple (yet annoying) effects of high wastewater contaminants can be bad odors and clogged drains.
The AEC High Efficiency Central Chillers are remarkably energy efficient and can save processors up to 60% in electrical costs. The system continuously measures ambient and process conditions and will adjust to operate in the most efficient manner.
In 2021, Process Cooling — with our sister publication, Process Heating — will play host to the inaugural Process Heating & Cooling Show, the only tradeshow to focus specifically on industrial applications.
Industrial refrigeration systems perform essential functions in food and beverage manufacturing and storage. The heart of the industrial refrigeration system is the compressor, and should the compressor need maintenance, time is of the essence.
A plant expansion includes additional space for production, testing and manufacturing of constant-conductance heat pipe (CCHP) lines at Advanced Cooling Technologies’ Lancaster, Pa., facility. The added space also provides ACT room to grow its space copper-water heat pipe (SCWHP) lines as industry adoption for box level electronics cooling increases.
Spig S.p.A., a subsidiary of Babcock & Wilcox Enterprises, has been awarded a contract to provide cooling technologies and associated services for an industrial facility. The total contract value is more than $18 million over approximately 10 years.
SPX Flow, through its Danish subsidiary SPX Flow Technology Danmark A/S, signed an agreement with Primodan A/S for the transfer of SPX Flow’s yellow cheese activities and technologies. The technology includes curd making, pressing and final brining systems.
The Sanhua Texas Technology Center (STTC) completed a year-long evaluation process and is now accredited to ISO/IEC specifications by the American Association for Laboratory Accreditation (A2LA). STTC opened in Houston, Texas, in late 2018.
Many types of pumps are suitable for use in the food industry, including rotary lobe, rotary piston, reciprocating positive displacement and air-operated double diaphragm designs. Traditional pumps, however, can be expensive to maintain while lobular pumps have low flow rates.
During winter operation, a cooling tower brings as much low temperature air into contact with the flowing water as the tower fan(s) will permit. The greater the flow of cold air, the colder the water temperature will become. Fortunately, when under design process heat loads, the temperature gradients that naturally occur in counterflow cooling towers prevent the mass flow of water from reaching 32°F.
The Danfoss CO2 adaptive liquid management (CALM) solution, which fully utilizes all of an evaporator's surface area and improves the energy efficiency of transcritical CO2 refrigeration systems by as much as a 10 percent, received top honors in the 2020 AHR Expo Innovation Awards program.
When it came time for one large fishing trawler to replace its on-site refrigerating plant, there were two solutions based on natural refrigerants: an ammonia system or a CO2 system. Global Seas opted for a CO2 system from Seattle-based Highland Refrigeration for its 148’ long Northern Defender.
Design-build firm Stellar updated its refrigeration parts and compressor shops in Jacksonville, Fla, and Fort Worth, Texas, in May 2019. Each facility offers climate-controlled storage spaces and a compressor shop with a separate teardown room, clean room and paint booth.
Americold entered into a strategic joint venture to own approximately 15 percent of SuperFrio Armazéns Gerais SA, a temperature-controlled storage operator in Brazil, for approximately $28 million. The closing of this transaction is expected to occur in the first quarter of 2020.
Texas Frio Cold Storage is building a freezer storage facility in Houston, Texas. The 43,742 ft2 facility will provide temperature-controlled freezer storage space for local food-service and restaurant operations. Construction should be complete by mid-2020.
United States Cold Storage (USCS) named Larry Alderfer as the company’s new president and chief executive officer (CEO). He succeeds David Harlan, who retired Dec. 31, 2019, after a 40-year career with the company.
Designed for plastics applications, the central drying and pre-conditioning system allows users to equip each drying hopper with its own 4” color touchscreen HMI, enabling independent operation, data monitoring and other control features.
As computer loads have increased, so has the generation of heat that is hard to reject with air-cooled solutions in data centers. Liquid-cooling methods used in data centers include rack cooling and on-chip heat rejection.
Designed to provide a stream of 20°F (-7°C) cold air to prevent heat buildup, reduce downtime and increase productivity, the Mini Cooler with dual-point hose kit is effective on small machining operations to eliminate burning, melting and heat-related breakage.
Picomag can be installed into any pipe up to 2” in diameter, including confined spaces. The plug-and-play electromagnetic flowmeter is suitable for process temperatures between 14 to 158°F (-10 to 70°C) as well as for process pressures up to 232 psi. It does not require inlet and outlet runs; therefore, it can be mounted directly before or after a pipe bend.
With the Ecodry 4.0 system, the company’s Microgel, Turbogel and Thermogel process-synchronized mold temperature control units are used to provide an operating temperature range of 41 to 392°C (5 to 200°C).
Smartpack is engineered to meet stringent low noise and high efficiency requirements in industrial heating, refrigeration and heat exchange applications. Construction of the plug-and-play fan packs includes a custom-configured Multi-Wing fan, an AC or EC motor, a fan guard and a shroud made from a strong metal frame with a plastic skin.
Engineered to simplify system design and optimize water and energy savings, Nexus is a plug-and-play, modular, hybrid fluid cooling system. The units are up to 8’ shorter in height, have a 40 percent smaller footprint and are 35 percent lighter than traditional fluid coolers, says the manufacturer.
Accuchiller TCF chiller uses a hybrid-film evaporator to provide the energy efficiency of wet (flooded) systems in a compact footprint using less refrigerant. Flooded evaporative systems immerse copper water tubes in liquid refrigerant; by contrast, hybrid-film evaporation systems use a thin film of refrigerant to achieve energy efficiency with less refrigerant.
