Brazed plate heat exchanger single-flow LUNA LD235LN-90L-DN80SS (connections: 4 stainless steel flanges) 0420-1235

Brazed Plate Heat Exchangers – Efficiency and Reliability in One

Brazed plate heat exchangers from the LUNA series are solutions designed for demanding heating and cooling installations. Made entirely of stainless steel materials, they not only provide high heat exchange efficiency but also exceptional resistance to corrosion and changes in operating parameters. Model LD235LN-90L, with stainless steel flanged connections, is ideal for applications where process hygiene and structural durability are key.

Construction and Application

The LUNA LD235LN-90L heat exchanger is a single-pass device, meaning that media flows through it in one direction. Vacuum brazing ensures tightness and a durable connection of the plates, eliminating the risk of leaks and ensuring stable operation for a long time. The construction based on stainless steel plates provides an optimal compromise between low flow resistance and high heat exchange efficiency. This solution minimizes the accumulation of impurities inside the exchanger, which translates into its reliability and ease of maintenance.

These types of heat exchangers are used in a wide range of installations, including:

• Central heating
• Refrigeration
• Industrial processes requiring precise temperature control
• Sanitary installations
• Heat recovery systems

Key Features and Benefits

• Durability and Resistance: Construction entirely of stainless steel materials ensures resistance to corrosion, pressure surges and temperature changes – even up to 200°C.
• High Efficiency: The optimal shape of the flow channels maximizes heat exchange while minimizing flow resistance.
• Tightness: The vacuum brazing process guarantees a durable and tight connection of the plates, eliminating the risk of leaks.
• Versatility: The ability to choose different connection sizes and a two-pass version allows you to adapt the heat exchanger to specific installation needs.
• Easy Installation: The compact design and standard flanged connections facilitate the installation and disassembly of the device.
• Compatibility with Insulation: The possibility of using insulation wrap allows reducing heat loss and improving the energy efficiency of the system.

This model is characterized by a nominal diameter of DN80 on both sides and a maximum working pressure of 16 bar. The dimensions of the heat exchanger are 310 mm wide and 788 mm high. The connections of the main circuit are made with an external thread, and the secondary circuit also with an external thread, ensuring easy installation in the existing infrastructure.
