Brazed plate heat exchanger, two-pass, LC110-40L-2S-DN50SS (connections: 6 stainless steel flanges) 0206-2180

Compact Performance in Demanding Thermal Conditions

This double-pass plate heat exchanger, built using copper-brazing technology, is designed for operation in demanding heating and cooling installations. Its construction enables efficient heat transfer between two liquid circuits, even under extreme operating parameters. Thanks to the use of stainless steel and vacuum furnace brazing, the unit achieves a high level of tightness and corrosion resistance, which is crucial when in constant contact with aggressive working media.

High resistance to pressure and temperature fluctuations makes this model suitable for applications where other devices might fail. It can operate with a flow temperature of up to 230 °C and withstand a maximum working pressure of 30 bar. This range of parameters makes it an ideal choice not only for standard heating systems but also for more complex industrial installations where safety and stability are priorities.

Application and Benefits of the Double-Pass Design

The specific designation of this model (2S) indicates a double-pass version. This means that the working fluid passes through the exchanger twice, significantly increasing the heat transfer surface area while maintaining compact dimensions. This solution is particularly advantageous in situations requiring high thermal loads within limited installation space.

• Flow Optimization: Flow channels are shaped to achieve a balance between low pressure drop and high efficiency. This not only improves the system's energy efficiency but also prevents the accumulation of contaminants inside the unit.
• Joint Durability: Permanent bonding of the plates through brazing eliminates the risk of leaks caused by mechanical clearances or gasket aging (which occur in gasketed heat exchangers).
• Mounting Versatility: The unit features nominal diameter connections of DN 50 on both sides (primary and secondary). These connections are provided as stainless steel flanges (6 pieces), facilitating integration with existing piping systems and ensuring a robust mechanical connection.

The unit dimensions are 466 mm in height and 258 mm in width, allowing installation even in tight technical cabinets or boiler rooms with limited volume. It is worth noting that this model is designed for installation within thermal insulation ("Suitable for insulation: yes"), which helps further reduce heat losses or prevent condensation of water vapor in cooling applications.

Thanks to the use of stainless steel as the main material and copper as the brazing filler, the unit exhibits high thermal conductivity. This directly translates into a faster response time of the heating or cooling system to load changes. The simple construction also facilitates disassembly for cleaning or maintenance, although the brazed tightness minimizes the need for frequent service interventions related to seals. This is a solution designed for long-term, trouble-free operation in standard liquid-to-liquid installations.
