Brazed plate heat exchanger, two-pass LD235-90L-2S-DN80SS (connections: 6 stainless steel flanges) 0255-0415

High Performance in a Compact Housing

This two-pass plate heat exchanger is a solution designed for installations where efficient heat transfer is a priority while maintaining a compact footprint. Thanks to its copper-brazed construction, the unit achieves high tightness and durability, eliminating the risk of leaks associated with traditional gaskets. The vacuum furnace brazing process ensures that each plate is permanently bonded to adjacent elements, resulting in resistance to varying operating conditions.

Applications and Key Advantages

The device is suitable for both standard heating and liquid-to-liquid cooling installations. Its construction allows operation under demanding thermal and pressure conditions, where flow temperature can reach 230 °C and maximum working pressure up to 30 bar. This range of parameters makes it suitable for systems requiring high operating temperatures and ensures safety even in circuits with high hydraulic stress. The entire unit is made of stainless steel, significantly extending the heat exchanger's service life in chemically aggressive environments.

Optimized channel geometry is not just theoretical – in practice, it means low flow resistance while maintaining high heat transfer efficiency. Importantly, this geometric arrangement prevents the accumulation of contaminants inside the channels, facilitating sustained system performance over time without the need for frequent cleaning inspections.

Installation and Connection Specifics

The heat exchanger features versatile mounting thanks to threaded (external) connections with a nominal diameter of DN 80 on both sides – on both the primary and secondary sides. In the two-pass version (designation 2S), the device offers increased heat transfer efficiency, which is crucial for installations with more demanding parameters.

For the installer, the physical dimensions of the unit and the possibility of insulation are also important: the total height is 788 mm, and the width is 310 mm. The design allows installation within a dedicated insulation jacket, which is essential when installing in technical rooms.

Simple installation and potential disassembly make this heat exchanger easy to service. Due to its high resistance to pressure and temperature fluctuations, the unit operates stably even during sudden spikes in heating or cooling network parameters. It is a solid choice for installations requiring reliability and long-term trouble-free operation without the need for additional protection against corrosion or thermal overloads.
