Heat Exchanger Market Growth Factors

Growth of Chemical and Petrochemical Industries

According to the American Chemical Society, the chemical industry in the U.S. witnessed a growth of 2.5% in 2019 and 3% in 2020. Major factors augmenting the development of the chemical industry in the U.S. include the expanding domestic end-use sectors. The increased chemical demand from various end-use applications further encourages new capital investment in the chemical industry. Heat exchangers are required for cooling, heating, and mixing substances in the chemical production process. The rapid expansion of the chemical industry is expected to be a significant factor in driving the heat exchangers market.

According to Deutsche Bank, China is expected to account for 45% of the revenue share in the global market by 2020. The rapid expansion of the chemical industry in Asia, especially in China, is expected to act as a significant driving force for the heat exchangers market on account of vast product penetration in various applications, including solvent condensation, multiple material mixtures, benzene heat recovery, cooling of water circuits, cooling of hydrocarbons, heating & cooling of intermediate products, heating & cooling of reactors, and production processes.

Growth of the Power Generation Industry

Significant power markets such as China, the United States, India, Russia, and Japan are rebuilding their production systems to adopt the structure of sustainable energy and efficient energy usage by constructing heat exchangers and changing away from traditional energy use. Over the projection period, this is likely to stimulate demand for heat exchangers.

According to the 5th Strategic Energy Plan approved by the government of Japan in 2018, the number of renewable energy and nuclear power plants has witnessed significant growth to ensure the country's self-sufficiency for energy requirements. The increasing demand for power plants is anticipated to augment the heat exchangers market growth in the country.

Emerging economies like India, China, and Brazil are expected to witness an increase in power demand owing to the increasing development and economic growth and the improvement in the quality of life. Several governments have established incentives to promote innovations and installations to increase power supply and reduce polluting gas emissions. The advancement of renewable energy technologies coupled with the close monitoring of energy consumption has enabled rapid expansion in power plants.

Restraining Factors

Regulations on Curbing the Use of Fluorinated Greenhouse Gas in Heat Exchangers

Hydrofluorocarbon (HFC), a type of F-gas, is emitted by heat exchangers (when in use) in various applications such as blowing agents for foam, refrigerants in HVAC refrigeration, fire-extinguishers, air-conditioner, and heat pump equipment. Rising F-gas emissions, regulatory standards, and strict regulations regarding the emission of manufactured gas are predicted to hinder the growth of the heat exchangers market over the forecast period.

According to the European Environmental Agency (EEA), the F-gas emissions doubled from 1990 to 2014, whereas the emission of other greenhouse gases declined. In response to the rising discharge of F-gas, the European Union has adopted the MAC Directive and F-gas regulation to limit fluorinated gas emissions.

The European Union is taking initiatives to curb F-gas emissions by implementing heat exchangers as a part of its policy to combat climate change. The first regulation was adopted in 2006 and successfully stabilized the levels of F-gas by 2010. The next set of rules was followed in January 2015, introducing and strengthening the policies and regulations.
