Types of Heat Exchangers: What You Must Know

It is very rare not to find a heat exchanger in a modern industrial plant. The heat exchangers are so critical to the plant’s operations that they may even determine the overall energy efficiency. Designing a good heat exchanger encompasses maintainability and types of fluids used, but we will try t[..]

Industrial refrigerant used in chillers and refrigeration plants

What is an ideal industrial refrigerant? There is no absolute answer to this question. No refrigerant fits the requirements 100 % for all cooling plants. An ideal refrigerant would need to have it all in terms of material compatibility, chemical stability, performance, non-toxicity, non-flammability[..]

Advanced refrigerants R1233ZD as substitute of R123

The debate over what is “the best” commercial refrigerant has been around and is unlikely to end anytime soon. Intensity on this matter is even increasing as leakage studies reveal the adverse effects of HFC emissions. The only way out for centralized systems is emissions reduction, which while poss[..]

How do absorption chillers work?

The original design of an absorption chiller is credited to the likes of Ferdinand Carré, Carl Munters and Baltzar Von Platen, renowned scientists who did their works between the 1850s and 1920s. While the products were first produced commercially in 1923, it was only in the 60s that serious product[..]

Pressure Test: Hydrostatic and Pneumatic Test Requirements

Pressure tests are a non-destructive way to guarantee the integrity of equipment such as pressure vessels, pipelines, plumbing lines, gas cylinders, boilers and fuel tanks. It is required by the piping codes to confirm that a piping system is able to bear its rated pressure and it has no leaks. Pres[..]

How to Reduce Carbon Footprint in Industry

About 25% of greenhouse effect emanates from the industrial sector, either directly or indirectly. Construction, food processing, mining and manufacturing are key industrial subsectors where diverse processes result in direct CO2 emissions. Power and heat require a lot of fossil fuel combustion. Pro[..]

Water Chiller Plant: many options available

There are many options available for generating chilled water. Perhaps none does so more efficiently than the water-cooled chiller, an essential part of Industrial Refrigeration. A water-cooled chiller is designed specifically to remove heat from a cooling system and transfer that heat elsewhere. Wa[..]

Heat Rejection: Which condensation technology is best?

During the refrigeration or industrial cooling cycle, heat is extracted from a cold system and thus needs to be rejected to a hot system. In order to achieve this, there are many heat rejection methods, and ARANER are specialists in the top 5 condensation technologies for heat rejection. First, the [..]
