Brazed plate heat exchanger two-pass LD235-70L-2S-DN80SS (connections: 6 stainless steel flanges) 0255-0413

Compact Performance in Demanding Conditions

The LD235-70L-2S-DN80SS brazed plate heat exchanger is designed for installations where not only efficient heat transfer but also resistance to extreme operating conditions is crucial. Thanks to its two-pass construction (designation 2S), this model offers significantly higher performance compared to standard single-pass versions, making it an ideal choice for more demanding heating or cooling system parameters. The entire unit is made of stainless steel, and the plate connections are secured by copper brazing in a vacuum furnace, ensuring tightness and durability even under high loads.

Applications and Key Structural Advantages

The device is suitable for liquid-to-liquid systems, both in heating applications and in cooling or industrial installations. Its core is an optimally shaped flow channel that strikes a balance between low flow resistance and high thermal efficiency. This arrangement not only accelerates heat exchange but also prevents the accumulation of contaminants inside the heat exchanger, reducing the risk of failures and extending the equipment's service life without the need for frequent maintenance.

Demanding operating environments pose no problem for this model – it handles temperatures up to 230 °C, allowing installation in high-temperature systems. System safety is ensured by resistance to a working pressure of up to 30 bar, protecting against damage even under peak network loads. Meanwhile, large nominal diameters of DN 80 on both sides (primary and secondary) enable free flow of large volumes of fluid without unnecessary energy losses.

Installation and System Versatility

For installers, ease of integration with existing infrastructure is key. The heat exchanger is equipped with six stainless steel flanges and threaded (external) connections, facilitating connection to main pipelines. Thanks to its compact dimensions (height 788 mm, width 310 mm), the unit occupies relatively little space despite its high thermal power, which is important when installing in boiler rooms with limited space.

Additionally, the heat exchanger's design allows for thermal insulation cladding ("For insulation cladding: yes"), minimizing heat loss at the installation point and increasing the efficiency of the entire heating system. Simple installation and disassembly mean that servicing the unit does not generate additional costs or downtime for the installation.
