Brazed plate heat exchanger double-pass LD235-100L-2S-DN80SS (connections: 6 stainless steel flanges) 0255-0416

High Performance in a Compact Housing

This two-pass plate heat exchanger from the L-line series is a solution designed for operation in demanding conditions where high thermal power is required within limited installation space. Thanks to its copper-brazed construction, the unit achieves high tightness and durability, eliminating the risk of leaks associated with traditional component joining methods. The vacuum furnace brazing process ensures that each plate is permanently bonded to its neighbors, resulting in resistance to variable pressures and temperatures. For this model, the maximum flow temperature reaches 230 °C, and the working pressure is 30 bar, making it suitable not only for standard heating installations but also for more demanding industrial or refrigeration applications.

Applications and Operational Benefits

The optimal shaping of flow channels is a key feature of this heat exchanger. Engineers designed them to achieve an ideal compromise between low flow resistance and maximum heat transfer efficiency. Importantly, this channel geometry prevents the accumulation of contaminants inside the unit, reducing the frequency of required inspections and cleanings. The two-pass version (denoted as "2S" in the name) enables higher efficiency under specific operating parameters, such as large temperature differences or specific flow requirements of the medium.

The unit is made entirely of stainless steel (SS), which ensures:

• High corrosion resistance – this material performs well with various types of working media.
• Long service life – stainless steel is more durable than standard alloys used in lower-cost constructions.
• Versatility – suitable for liquid-to-liquid installations in both heating and cooling systems.

Installation and Connection Parameters

Installation of this model is simplified by the use of stainless steel flanges with a nominal diameter of DN 80 on both sides (primary and secondary). The connections feature external threads, facilitating integration with existing piping systems. It is worth noting that the unit has dimensions allowing placement even in spaces with limited room – its height is 788 mm with a width of 310 mm.

Despite its relatively compact size, this heat exchanger can handle high thermal loads. The construction also allows for optional insulation cladding (according to the information "Suitable for insulation cladding: yes"), which may be important when installing in unheated rooms or where energy-saving requirements apply. Simple assembly and disassembly facilitate future servicing or system upgrades without the need to replace the entire piping network.

Thanks to the combination of a robust stainless steel construction with advanced flow channel geometry, this heat exchanger offers reliable operation for many years, simultaneously minimizing energy losses and the risk of failures related to fouling or corrosion. It is the choice for installers seeking a "turnkey" solution that does not require complex maintenance procedures during operation. All key technical data regarding a working pressure up to 30 bar and a temperature up to 230 °C have been incorporated into the design process to ensure safe operation under challenging environmental conditions.
