Application areas
oil&gas | refinery
Oil and natural gas are fundamental in our time. Refineries are complex buildings and depend on round-the-clock operations. Avoiding unexpected and costly shut-downs requires robust and reliable technologies that can operate efficiently and cost-effectively in the harshest of environments.
PETROchemical
Chemistry combined with petrochemistry is the biggest market of heat exchangers in the industry. It is easily understandable if we consider the conception of the production processes which requires numerous stages of heat transfer. Nexson heat exchangers are adapted to comply with environmental constraints and high-pressure requirements.
mining & steel
Production processes in heavy industry are often energy-intensive and generate a lot of heat. The big challenge is to keep production running smoothly despite the high temperature. Thanks to Nexson people great experience and the heat exchangers solutions offered, you will get the required performance and efficiency.
pulp & paper
Paper use increases year on year, and has quadrupled over the past 50 years. Surrounded by continuously growing competition, the main goal of each plant is increasing its processes efficiency. Correctly organizing heat transfer for every stage of the manufacturing process is what plays the most important role in increasing the efficiency.
power
To compensate the lack of energy in the future, solar energy is one of the best alternative. It is the renewable energy that has the most significant growth potential.
The Concentrating Solar Power (CSP) technology uses large sun-tracking mirrors to concentrate solar radiation. Products such as Spiral and condensers are needed.
agro industries
The agro industry sector which groups industries so varied as starch, vegetable oil, brewery, food and sugar has become over the years a large consumer of heat exchangers.
It actually consumes a lot of energy and can lose it just as much. Hence the interest to think of getting back the heat via a Nexson customized heat exchanger, the reliability and cost effectiveness of which comply with the current food-processing standards.
PHARMACEUTICAL
Pharmaceutical industry requires the highest hygienic standards in accordance with GMP (Good Manufacturing Practice). Nexson heat exchangers are specially designed to meet the high sanitary requirements of this industry. They can be used for heating, cooling, and tempering
pharmaceutical products.
environment
Heat exchangers play an essential role in pollution prevention and in the reduction of environmental impact of industrial processes, by reducing energy consumption or recovering energy from processes in which they are used. Nexson spiral heat exchangers are specially designed for this process. They allow to handle big particles / fibers without any fouling or process shutdown.
