Thermal spray coating is an industrial coating process that consists of a heat source (flame or other) and a coating material (in powder or wire form). The coating is melted into tiny droplets and sprayed onto a surface at high velocity. Upon impact, a bond forms with the surface. Repeated passes build up the thermal spray coating and form a layered structure.
When treating wastewater, sludge and digestate, it often can be beneficial to reduce the volume of material or increase the solids content as well. Mechanical dewatering via a centrifuge or belt press — to separate solids and liquids — is standard for the water treatment and anaerobic digestion sectors.
It is critical that process cooling systems relying on cooling towers have robust but cost-effective filtration equipment for water reuse. Cooling tower water frequently contains hazardous materials that should be managed to avoid reintroducing them into the process cooling equipment or system.
In the 1960s, the steel production industry sought a way to filter the cooling water used to cool steel production. During production, both free solid material from the line, and residual oils from previous formation steps, would be on the materials being cooled.
Industrial refrigeration systems have long taken a standardized approach when it comes to their design and construction. Over time, industrial cooling trended toward no longer being engineered so much as replicated, using decades-old but proven designs. This was the case even for new facilities. Ultimately, the results were that industrial cooling systems were falling behind in terms of available technology.
I would like to say first, to our readers, advertisers, contributors and partners, THANK YOU! As the new group publisher for the Thermal Processing Group at BNP Media, I’m looking forward to continuing to build on our long-standing brands.
Bitzer’s CSVH compact screw compressors won the Best Application Compressor award at the Global Logistics Excellence Awards in Hyderabad, India. The inverter-driven compressors are optimized for air-cooled liquid chillers and heat pumps.
The 2019 R&T Forum will be held at the Pyle Center on the campus of the University of Wisconsin in Madison. The annual training meeting of the Industrial Refrigeration Consortium, planned for May 8-9, includes an agenda that explores ways to improve industrial ammonia refrigeration systems.
Designed for installers and service technicians in the industrial refrigeration space, an industrial refrigeration app helps users navigate different product categories and types to find the right spare part kit. They can view images and data sheets, in addition to previously available illustrations and documentation, to see which parts are included and their specifications.
The 25th IIR International Congress of Refrigeration (ICR 2019) will be held August 24-30 in Montreal. The event’s theme, “Refrigeration for Human Health and Future Prosperity”, will focus on energy saving and energy efficiency, food supply, health, reduction of global warming and protection of the ozone layer.
A fluid cooler model incorporates finned coils to expand thermal performance and permit dry operation during a broader range of ambient temperatures. Marley DT can more effectively reject heat without evaporating water at ambient temperatures up to 20 degrees higher than with bare tube coils, which helps reduce costs associated with water usage, water treatment and pump energy.
Recently revised AMCA Publication 802, Industrial Process/Power Generation Fans: Establishing Performance Using Laboratory Models, outlines methods used by manufacturers to determine the performance of full-size industrial-process and power-generation fans. Changes to it include...
A case history from Hillphoenix details how the company supplied several industrial systems for a North American customer. In total, 250,000 ft2 of refrigeration space was created for a warehouse distribution center.
Three large compressors have been installed behind a glass wall in the meeting center at Danfoss headquarters in Denmark so customers and guests can see the product in operation. The Turbocor units provide cooling for the ventilation system and other cooling systems in the main office building.
A recently opened testing facility in Merate, Italy, will verify a pump’s capacity as well as its net positive suction head (NPSH) behavior, vibration and noise levels, and overall operational efficiency.
Lineage Logistics, a provider of temperature-controlled logistics solutions, signed a definitive agreement to acquire Preferred Freezer Services, a global network of temperature-controlled warehouses. The combined company will operate more than 1.3 billion ft3 of temperature-controlled capacity across 200 facilities in North America, Europe and Asia.
The second phase of a 330,000 ft2 cold storage distribution center in Sioux Falls, S.D., a project that will create over 100 new jobs, is complete. The 57’ tall facility includes freezers with temperatures from 0°F to -20°F that hold over 54,500 pallet positions, storing frozen protein products.
Tippmann Innovation and Table Talk Pies broke ground on cold storage facility in Worcester, Mass., that sits adjacent to the pie maker’s 150,000 ft2 manufacturing facility. The 34,00 ft2 -10°F freezer warehouse with 3,440 pallet positions will enable Table Talk to streamline its production and distribution processes.
Designed for indoor, outdoor, remote and washdown applications that require a closed-loop system to protect electronics, PKS Series can be used to cool sealed enclosures and is suited for cooling industrial electrical components that need dust protection.
The intelliGen is a factory-mounted electronic control solution for evaporators that provides automatic superheat adjustment, temperature control and intelligent defrost control capability for walk-in coolers and freezers.
Heater/chiller units offer configurability and compactness via a single combined package. The integrated system saves space because both circuits are contained in one cabinet and are managed by a single controller.
Due to a smaller heat exchanger in the Tempro Series, there is less circulating water. As a result, the preheating and cooldown periods are shorter, says the manufacturer. The product line includes Tempro plus D90, which is designed for temperatures up to 194°F (90°C).
