/Heat Exchanger

Heat Exchangers

A  heat exchanger  is a device used to transfer heat between a solid object and a  fluid , or between two or more fluids. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. Exchangers are widely used in space heating , refrigeration , air conditioning ,power stations , chemical plants ,  petrochemical plants ,  petroleum refineries ,  natural-gas processing , and  sewage treatment.

At ESI Technologies we supply a range of heat exchangers including plate & frame, shell & tube and brazed. We will be happy to discuss your requirements and advise the best option for your process.

Pharma Line

Alfa Laval Pharma-line is a high-quality shell-and-tube heat exchanger especially developed to meet the high hygienic demands of the pharmaceutical industry. Flexibility in the design makes it suitable for many hygienic applications, whatever the demands.

Industrial Semi-Welded Line

Alfa Laval Industrial semi-welded line handles most refrigerants and is particularly suitable for applications involving ammonia. Semi-welded heat exchangers are used in both organic and inorganic chemical processing when the chemicals involved limit the selection of gaskets that can be used or when the required design pressure makes fully gasketed plate-and-frame heat exchangers insufficient.
