With the increasing need for refrigeration, compressors are being developed in numbers and with better technology. However, the basics still stand. With the many refrigeration compressor types available, selecting one for your application can be overwhelming. Some factors to consider for the best un[..]

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[..]

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[..]

By now, you probably know that ARANER is a global brand in matters Industrial Refrigeration Engineering. The firm provides efficient energy solutions, a full range of standard or customized products as well as tailor-made professional solutions and services in a minimal amount of time. In the course[..]

The healthcare industry consumes loads of energy and release a lot of waste into the environment. Equipment working on a 24/7 basis- ICU machines, CT scanners- and at full power mode is unavoidable. Some healthcare managers opine that reducing environmental impact and lowering electricity bills rema[..]

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[..]

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 [..]

The Montreal Protocol is an international agreement designed to protect the ozone layer by phasing out the production and consumption of ozone-depleting substances (ODS). The agreement, finalized in 1987, is designed to protect the ozone layer which filters out harmful ultraviolet radiation. Ultravi[..]

Maintenance of large-scale industrial refrigeration units is arguably at the top of the list when it comes to the reliability, performance, and efficiency of the equipment. Preventative maintenance is essential to help avoid breakdowns and outages in the future and keeping your equipment working rel[..]

The Vapor Compression Refrigeration Cycle is nearly 200 years old, but it does not seem ready to leave the scene any time soon. While some people have viewed this method as environmentally harmful and inefficient, the cycle is still applicable in the industrial sphere. Natural gas plants, petroleum [..]

From the beginning of industrial refrigeration, when in the nineteenth century the first systems were developed for applications related to the food industry, until today, where the applications are increasingly diverse (District Cooling, Electricity Production, and Data Centers, amongst others), a [..]

One of the most widespread refrigerants used in the field of industrial cooling is R717 (Ammonia). The selection of the refrigerant is based on process parameters such as cooling temperature requirement, condensing pressure, plant nature, location, efficiency, etc… or simply due to availability.
