Brazed plate heat exchanger double-pass LD235-180L-2S-DN80SS (connections: 6 stainless steel flanges) 0255-0424

Compact Performance in Demanding Thermal Conditions

The LD235-180L-2S-DN80SS brazed plate heat exchanger is designed for demanding installations where efficient heat transfer and resistance to extreme operating parameters are critical. Thanks to its two-pass construction (designation "2S"), this model offers increased performance compared to standard single-pass versions, making it an ideal choice for circuits with specific hydraulic requirements or large temperature differences. The unit, entirely made of stainless steel and brazed with copper in a vacuum furnace, ensures tightness and high corrosion resistance, which is particularly important in liquid-to-liquid heating and cooling installations.

Applications and Load Resistance

The device is suitable for both central heating systems and industrial or refrigeration installations. Its construction allows operation with a maximum flow temperature of up to 230 °C and withstands a working pressure of 30 bar. This durability ensures safety even during sudden network parameter surges. The nominal diameter connections DN 80 on both sides (primary and secondary) are provided as external threads, facilitating integration with existing pipelines. It is worth noting that despite its significant thermal capabilities, the unit maintains relatively compact dimensions (height 788 mm, width 310 mm), easing installation in limited boiler room or technical space.

Key Structural Features and Operational Benefits

The optimized design of flow channels is one of the pillars of this model, ensuring a good compromise between low flow resistance and high heat exchange efficiency. This reduces the risk of contaminant accumulation inside the unit, translating into longer service life and lower maintenance costs. The tightness of plate joints results from a precise brazing process, eliminating the need for rubber gaskets susceptible to aging.

For installers, it is also important that the device supports the installation of thermal insulation ("Suitable for insulation: yes"), allowing reduction of heat losses in technical rooms and improving the overall energy efficiency of the system. Simple installation and potential disassembly result from the device's thoughtful geometry and standard threaded connections, shortening installation time. Thanks to high resistance to pressure and temperature fluctuations, this heat exchanger minimizes the risk of failures caused by cyclic thermal loads characteristic of modern heating systems.
