Brazed plate heat exchanger single-flow LB31-20-1" (connections: 4 male threads) 0203-0062

Plate heat exchangers – efficient heating and cooling

The LB31-20-1” brazed single-pass plate heat exchanger is an advanced device used for efficient heat exchange between two independent fluid circuits. The construction based on brazed stainless steel plates ensures high tightness and durability, and the compact dimensions facilitate installation even in limited spaces. This is an ideal solution for both installers and users looking for a reliable and efficient heating or cooling system.

Construction and application

The LB31-20 heat exchanger consists of a package of corrugated stainless steel plates, permanently joined by vacuum brazing. This construction provides a large heat exchange surface area with relatively small dimensions. The single-pass arrangement optimizes fluid flow, minimizing pressure drop and increasing energy exchange efficiency. The device finds wide application in:

• Central heating – heating domestic hot water using a heat source (e.g., a boiler).
• Underfloor heating – integration with low-temperature systems.
• Solar and geothermal heating systems – utilizing renewable energy sources.
• Industrial processes – cooling machines and equipment, temperature regulation in technological processes.
• Condensers and evaporators in heat pumps – increasing energy efficiency.

Key features and benefits

• High efficiency: The corrugated plate surface increases the heat exchange area, ensuring efficient energy transfer between the heating medium and the heat receiving medium.
• Durability and tightness: Vacuum brazing guarantees a durable connection of the plates, eliminating the risk of leaks and ensuring long-term trouble-free operation of the device.
• Corrosion resistance: Stainless steel construction provides resistance to aggressive media, extending the life of the exchanger even in harsh operating conditions.
• Compact dimensions: Small dimensions facilitate installation in tight spaces, which is particularly important during the modernization of existing installations.
• Wide temperature range: The ability to operate in a temperature range from -195°C to 230°C makes the exchanger versatile and can be used in various applications.
• Safety: The maximum working pressure of 30 bar ensures safe operation of the device even in demanding working conditions.
• GZ 1 inch connections: Allow easy connection to standard piping installations with external threads.

Additionally, the exchanger's design minimizes the accumulation of contaminants, which translates to stable operation and long life of the device. Therefore, it does not require frequent cleaning or maintenance. Insulation jacket - yes, which helps reduce heat loss during operation of the device.
