Compressors, often referred to as the heart of the refrigeration cycle, are typically the largest energy consumers. Condensers fill the role of rejecting heat from a refrigerated space to the atmosphere by condensing the refrigerant.
Design-build companies provide single-source responsibility for all aspects of a project. For users of process cooling, the design-build approach means that single supplier — with a team consisting of architects, refrigeration engineers, designers and contracting field engineers, among others — helps eliminate overlap in design and construction phases, streamlining project completion. In addition, the processor has a single supplier that takes full responsibility for the project from conception to completion.
BioSpray Tower will disinfect hard, nonporous surfaces, says the manufacturer. The EPA-registered disinfectant kills 99.9 percent of Legionella pneumophila when correctly applied to hard, nonporous surfaces like cooling towers.
The number of cooling towers used for industrial applications and HVAC systems in the United States was estimated at 500,000 to 600,000 towers in a report by Pacific Northwest Laboratory in 1995. Based on that value and the intervening years, we can extrapolate that the number of cooling towers worldwide can be estimated at 1.5 million.
For those involved in the process industries, three shows this fall offer a chance to see new and upgraded products firsthand, learn about emerging technologies and network with others in the industry.
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.
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.
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.
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.
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).
Attendees of the IIAR Natural Refrigeration Conference & Heavy Equipment Expo come from all facets of the industry including design engineers, contractors, end-users, academics, scientists, trainers, and government agencies.
