A steam turbine surface condenser is a heat exchanger that condenses steam from a steam turbine into water. The condenser is mainly used in the steam turbine power plant. In addition to condensing the exhaust steam of the steam turbine into water for reuse by the boiler, the condenser can also establish a vacuum and maintain a vacuum at the steam exhaust of the turbine.

According to the "2017-2021 Steam Turbine Surface Condenser Industry Venture Capital Situation and Investment and Financing Strategy Guidelines Report" released by the New World Industrial Research Center, the steam turbine surface condenser is the largest auxiliary equipment for steam turbines. One of the most important auxiliary equipment of the wheel engine group, its important function is to condense steam discharged from steam turbines and small machines, discharge water from hot wells, receive, distribute and discharge steam and steam extraction lines from steam turbine bypass systems and The hydrophobicity of the other parts. Therefore, steam turbine surface condensers are widely used in thermal power plants and nuclear power plants. At the same time, steam turbine surface condensers have many applications in the industrial drive and marine industries.

European countries have relatively developed economies and dense populations. The local water resources are abundant, there are many large hydropower stations; and thermal power stations, nuclear power plants, solar power plants, wind power, etc. provide electricity for European countries. The thermal power station is the earliest power station and currently has a relatively large share of energy supply in European countries. Therefore, the turbine surface condenser is in stable demand in Europe and has a large market.
