Brazed plate heat exchanger counterflow LUNA LA14LN-40-2-3/4" (connections: 4 male threads) 0420-0310

Brazed plate heat exchangers from the LUNA series are advanced solutions for efficient heat exchange, entirely made of high-quality stainless steel materials. The brazed construction ensures not only durability and corrosion resistance but also high hygiene, making them an ideal choice for various applications in heating, cooling, and industrial systems. Model LA14LN-40-2-3/4" features a two-flow design and GZ 3/4 inch connections, providing installation flexibility and easy integration with existing infrastructure.

Construction and performance

LUNA heat exchangers are characterized by an optimal shape of the flow channels. This solution allows for achieving high heat exchange efficiency while maintaining low flow resistance, minimizing the risk of contamination buildup. The permanent bonding of the plates, achieved through vacuum furnace brazing, guarantees tightness and reliable operation for a long time. The use of stainless steel brazing alloy eliminates the risk of galvanic corrosion and ensures compatibility with various working fluids.

Parameters and application

This specific model – LA14LN-40-2-3/4" – has a nominal diameter of 3/4 inch on both the primary and secondary sides. The maximum flow temperature is 200°C, and the maximum working pressure is 20 bar. The heat exchanger is designed for mounting with insulation, which minimizes heat loss and increases the energy efficiency of the system. The two-way flow makes it a particularly effective solution in applications requiring heat recovery or precise temperature control.
