Brazed plate heat exchanger two-pass LC110-30L-2S-DN50SS (connections: 6 stainless steel flanges) 0206-2179

Heat exchanger for demanding liquid-to-liquid installations

This two-pass plate heat exchanger, constructed using copper brazing technology, is a solution dedicated to heating and cooling installations where high performance is critical within limited installation space. Its construction is based on stainless steel plates, which, combined with the vacuum furnace brazing process, guarantee tightness and durability even under demanding operating conditions. Thanks to the use of six stainless steel flanges with a nominal diameter of DN 50 on both sides (primary and secondary), the device ensures connection flexibility and corrosion resistance, which is particularly important in systems with aggressive working media.

Application and key structural advantages

The device has been designed to optimally shape the flow channels. This is not just a matter of theory – in practice, it means a compromise between low flow resistance and high heat transfer efficiency. Thanks to this, the heat exchanger not only efficiently transfers energy but also prevents the accumulation of contaminants inside the channels, extending its service life and reducing the need for maintenance. The two-pass version (designated by the symbol 2S) is characterized by high performance even under more demanding operating parameters, making it an ideal choice for circuits with high thermal loads.

Key operating parameters define the application range of this model: the device operates without problems at temperatures up to 230 °C, allowing its installation in high-temperature systems, and the maximum working pressure is 30 bar, ensuring safety in vacuum and pressurized systems. With dimensions of 466 mm in height and 258 mm in width, the device offers high heat transfer capacity in a relatively compact housing. External thread connections facilitate integration with existing infrastructure, and the possibility of insulation (according to the marking "Suitable for insulation: yes") allows for effective reduction of heat losses or water vapor condensation.

Durability and operating conditions

The stainless steel used for the plates and copper brazing provide high corrosion resistance and strength against cyclic temperature and pressure changes. This means that the heat exchanger maintains its properties for a long time, even with frequent fluctuations in the parameters of the heating or cooling network. Simple installation and potential disassembly (in case of cleaning or gasket replacement in other types, although here we have permanent brazing) are facilitated by the device's thoughtful geometry.

Basic data influencing the selection of the device for the installation include the material made of stainless steel combined with copper brazing and a nominal diameter of 50 mm on both the primary and secondary sides. The connections are made as external threads using six stainless steel flanges. The device handles a maximum temperature of 230 °C and a maximum working pressure of 30 bar. External dimensions are a height of 466 mm and a width of 258 mm, and the flow type is the two-pass version (2S).

Thanks to these structural features, the device proves itself in both modern industrial boiler rooms and smaller commercial installations where reliability is a priority. The optimal shaping of flow channels means there is no need to worry about sudden drops in performance caused by scale or other contaminant deposition – the flow is stable and predictable. This is a solution for installers seeking proven technology and for end-users valuing the energy efficiency of heating or cooling systems.
