Coolselector®2 helps you optimize energy consumption and increase efficiency in any HVACR system. Run unbiased calculations based on a set of operating conditions — such as cooling capacity, refrigerant, evaporation, and condensation temperature — and then select the best components for your design. We’ve removed the complexity from the equation so that you can focus on what you do best: being awesome.



Now, we’re putting more resources at your fingertips that make Coolselector®2 an even more valuable and useful part of your digital toolbox.

Why use Coolselector®2 

Creating new designs from the ground up, or making improvements to existing system, can be complicated and time-consuming. Large amounts of data need to be calculated and analyzed to determine the best components for a high-performance system. Your clients and colleagues expect skimmable reports, so they can quickly make use of your findings. And, of course, you need the code numbers to order the specified components when you’re ready to start assembling or retrofitting the system.

Coolselector®2 streamlines these processes, so you can focus on applying your expertise rather than getting buried in the details.

You can even use Coolselector®2 to perform calculations for multiple components at once. The “components in series” function offers a powerful way of calculating and connecting valves and line components. Coolselector®2 can also suggest the ideal grouping of Danfoss components for commercial and industrial applications, such as cold rooms and evaporator valve stations.

Oil & Gas : Protect petroleum workers from radioactive material with personal dosimeter

The oil and gas industry is responsible for releasing radioactive materials through its extraction, drilling, fracking, and production activities. Oil and gas production involves the use of various types of radiation, including gamma rays, x-rays, and neutrons. Some of these emissions are potentially dangerous to human health and the environment. Electronic personal dosimeters are used to properly monitor workers’ exposure to radioactivity.

In this article, we will discuss the sources of radioactive emissions in oil and gas production and how they are monitored. We will also look at some of the safety measures that are in place to protect workers from exposure to these harmful emissions.


Oil & Gas Industry and Radiation Exposure

Oil & Gas Industry and Radiation ExposureThe oil and gas industry is always looking for ways to improve efficiency while maintaining a high standard of safety, regardless of the harsh climate conditions and environmental challenges.

The oil and gas industry has several sectors, which include the construction, exploration, production, downstream, and marketing sectors: the construction sector is responsible for manufacturing and fabricating facilities and equipment, the exploration sector is responsible for finding and evaluating new resources, and the production sector is responsible for developing and exploiting commercially viable oil and gas fields.

Even though petroleum and oil exploration have usually been associated with the bi-product of combustion contaminants, such as CO2 or greenhouse gases (GHGs), it is often forgotten that these same processes can expose many workers to radiation.

Those who live near oil exploration and processing facilities may be at risk of exposure to potential radiation through radioactive substances and may be vulnerable to the harmful effects of radiation.

Strict controls must be implemented to protect both workers and the general public from harmful radiation exposure as well as radioactive waste or chemical hazardous waste.

Oil and gas companies are highly reliant on specialized service and supply companies to provide the necessary equipment and expertise like rt inspection (Radiographic Testing) which includes radiation safety.

The Radiation Protection Supervisor (RPS)  is responsible within the organization for the supervision of work involving ionizing radiation.

The third agricultural revolution will not be possible without the use of fertilisers.

The-third-agricultural-revolutionProducing more is becoming essential, while agricultural land is shrinking.

Organic farming dreamed of chemical-free crops that would preserve our health and our environment. Today, the dream of the 1980s is coming up against the reality of the soil: without help, the land is depleted.


The Food and Agriculture Organisation of the United Nations (FAO) estimates that food production will have to increase by 70% to feed the additional 2.3 billion people on our planet by 2050. At the same time, the area of cultivated land is constantly decreasing.

Cultivated agricultural land accounted for 5 billion hectares worldwide. But every year, more than 3 million hectares are severely degraded.

Today, nearly 5 million hectars of our arable land are lost yearly.

Prysmian Powerlink CCO D. Waimann: “With 1,200 km of hvdc underground cable, we are advancing the energy transition in Germany and Europe”

MILAN, ITALY   –   10/14/2022 – 10:52 AM

With the start of cable production at Prysmian Group, SuedLink, the largest infrastructure project of the energy transition in Germany with a length of around 700 kilometres and 4 GW of transmission capacity, has reached another milestone. Prysmian started the production of a ±525 kV HVDC underground cable system at its French plant in Montereau, which allows a transmittable power of 2 gigawatts on a single system.

The transmission system operators TransnetBW GmbH and TenneT TSO GmbH have commissioned the globally operating cable manufacturer based in Milan to plan, manufacture, deliver and install a 580 km section of SuedLink. It connects Wilster in Schleswig-Holstein via the north-west of Hamburg to the southern connection point in Bergrheinfeld near Schweinfurt in Bavaria. The two transmission system operators have awarded the cable supplies for SuedLink in two lots for their respective areas of responsibility. For the connection from Brunsbüttel in Schleswig-Holstein to Leingarten in Baden-Württemberg the company NKT is in charge.

Space-saving installation with high transmittable power

The ±525 kV underground cables for SuedLink are designed with large conductor cross-sections for high transmittable power over long distances. A particular advantage is minimized space consumption – the ±525 kV technology allows a reduced amount of cable to transmit the same power compared to 320 kV systems, for example. This means less construction effort is required when installing the system, including trench widths.

We are pleased to now produce a first significant part of the large cable volumes that will drive the energy transition in Germany and Europe over the next few years,” explains Detlev Waimann, CCO Prysmian Powerlink. “Through parallel, early production in several European plants, we can – in coordination with the transmission system operators – optimize the future project processes.

What are frequency to current converters and what are they used for?


The process industry requires measurement and control of many process variables. Speed and flow rate are two such variables, where safety and product delivery demand accurate process control.

Sensors used to measure speed often take the form of proximity sensors, which detect a target as it passes by the sensor resulting in a pulse or frequency output proportional to the speed.

To enable these signals to interface with downstream equipment, the pulses or frequencies are often converted to a current or voltage signal. Frequency to current converters such as the PR 4225 and PR 3225 are used for this purpose.
