Brazed plate heat exchanger two-pass LC170-140-2S-DN50SS (connections: 6 stainless steel flanges) 0207-1506

Heat Exchanger for Demanding Liquid-to-Liquid Installations

This double-pass plate heat exchanger from the L-Line series is designed for operation in challenging conditions, where high performance is critical alongside resistance to significant thermal loads. Based on a construction of 140 copper-brazed stainless steel plates, the unit effectively transfers heat in heating and cooling systems, achieving flow temperatures of up to 230 °C. The special shaping of the flow channels not only minimizes hydraulic resistance but also prevents the accumulation of contaminants, resulting in a longer installation lifespan and lower maintenance costs.

Application and Mounting Flexibility

The unit is ideal for applications where standard single-pass solutions are insufficient. The double-pass version (designation 2S) enables superior heat exchange parameters under more demanding operating conditions, which is particularly important in modern boiler rooms or industrial cooling systems. A key structural element consists of 6 stainless steel flanges with a nominal diameter of DN 50, ensuring a solid connection to the installation. This connection configuration facilitates mounting in systems with high flow rates and eliminates the risk of corrosion at points of contact with aggressive working media.

It is worth noting that despite its high thermal capacity, the heat exchanger maintains relatively compact dimensions (height 688 mm, width 258 mm), facilitating integration into tight technical spaces. The design also allows for the use of an external insulation jacket, which is standard in professional installations aiming to maximize energy efficiency.

Durability and Operational Safety

Operational safety is guaranteed by the vacuum brazing process, which ensures a permanent bond between the plates and complete tightness of the entire system. Consequently, the unit exhibits high resistance to pressure changes (up to 30 bar) and temperature fluctuations, eliminating the risk of failures resulting from cyclic thermal loads. The stainless steel used for the plates and connections further enhances corrosion resistance, making this model an ideal choice for installations requiring long-term reliability without the need for frequent inspections or component replacement.

• The double-pass configuration significantly increases heat exchange efficiency in systems with high thermal requirements.
• The use of stainless steel guarantees corrosion resistance and longevity, even when operating with hard water or chemicals.
• Six DN 50 connections enable connection to high-flow installations without the need for additional reducers.
• Operation at temperatures up to 230 °C allows the unit to be used in high-temperature systems, e.g., with condensing or steam boilers (after appropriate adaptation).
• The vacuum brazing process ensures permanent tightness and resistance to material fatigue resulting from heating and cooling cycles.
