Brazed plate heat exchanger double-pass LC110-60L-2S-DN50SS (connections: 6 stainless steel flanges) 0206-2182

Compact Performance in Demanding Conditions

The L-line series brazed plate heat exchanger is designed for demanding heating and cooling installations where both efficiency and durability are critical. Featuring a two-pass construction, this model delivers high heat transfer performance even under complex operating parameters. Thanks to the optimized flow channel geometry, the unit achieves an optimal balance between low flow resistance and maximum thermal energy utilization. Importantly, this design minimizes the risk of contaminant accumulation within the channels, extending the service life of the installation and reducing maintenance costs.

Robust Construction and Resistance to Extreme Conditions

The key advantage of this heat exchanger is its resistance to high thermal and pressure loads. The unit operates safely at a maximum flow temperature of 230 °C and a working pressure of up to 30 bar. This durability is achieved through copper brazing in a vacuum furnace, ensuring a permanent bond between plates and complete structural integrity. The entire assembly is made of stainless steel, providing excellent corrosion resistance – essential in installations using water with varying chemical compositions. Despite its compact dimensions (height 466 mm, width 258 mm), the unit handles high thermal loads, making it ideal for applications with limited installation space.

Application and Easy Integration into the Installation

Thanks to its two-pass design and large nominal diameter DN 50 on both sides (primary and secondary), the heat exchanger is suitable for systems requiring high media flow rates. The connections are provided as stainless steel flanges (6 pieces), facilitating installation in heavy-duty industrial systems or large municipal facilities. Notably, the unit is compatible with insulation jackets, allowing effective reduction of heat or cold losses depending on the application. Simple installation and disassembly enable installers to quickly adapt it to existing infrastructure without the need for complex auxiliary solutions.

• Two-pass construction enhances performance under challenging operating conditions, enabling more efficient heat transfer compared to single-pass versions.
• Copper brazing ensures leak-tightness and resistance to pressure fluctuations without the need for rubber gaskets, which can age over time.
• Stainless steel protects against corrosion in aggressive environments, which is particularly important in industrial installations.
• DN 50 connections enable operation with high media flow rates, eliminating hydraulic bottlenecks in the system.
• Temperature up to 230°C allows use in high-temperature systems such as condensing boilers or industrial heat supply systems.

This unit requires no specialized tools for installation beyond standard HVACR industry equipment. Its versatility makes it suitable for both modern gas or oil boiler rooms and systems utilizing waste heat or renewable energy sources. Thanks to the absence of rubber gaskets (replaced by brazing), issues related to gasket aging or leaks caused by thermal cycles are eliminated – a truly "set-and-forget" solution.
