Brazed plate heat exchanger single-flow LB31-30-1" (connections: 4 male threads) 0203-0063

Plate heat exchangers – efficient heat exchange in your system

The LB31-30-1" brazed single-pass plate heat exchanger is a key component of heating and cooling installations, providing high efficiency with relatively small dimensions. The construction based on brazed stainless steel plates guarantees durability and reliability, and the optimal fluid flow minimizes energy losses. This is an ideal solution for both professional installers and users looking for an effective way to transfer heat.

Construction and application

The LB31-30 heat exchanger uses corrugated stainless steel plates, permanently joined by vacuum brazing. This process ensures tightness and corrosion resistance, which translates into a long service life. The single-pass design ensures that fluids flow through the channels formed between the plates in an orderly manner, maximizing heat exchange.

The device finds application in:

• Central heating,
• Domestic hot water heating,
• Solar and geothermal heating systems,
• Industrial cooling installations (oil coolers),
• Condensers and evaporators in heat pumps.

Key features and benefits

• High efficiency: The optimal shape of the flow channels provides a compromise between low flow resistance and high heat exchange efficiency. This prevents the accumulation of impurities inside the heat exchanger.
• Durability and tightness: The vacuum brazing process guarantees a permanent connection of the plates, eliminating the risk of leaks and ensuring reliable operation for a long time.
• Resistance to working conditions: Made of stainless steel, the heat exchanger is resistant to corrosion and changes in temperature (up to 230°C) and pressure (up to 30 bar).
• Compact dimensions: Small dimensions allow for easy installation even in limited spaces. The dimensions of the device are 123 mm wide, 286 mm high and 28 mm deep.
• Versatility: GZ 1 inch connections allow easy connection to different types of installations. It has four ports with external thread.
• Power: The device with a power of 33 kW allows for efficient heating or cooling of the medium flowing through the heat exchanger.
• Number of plates: 30 plates provide a large heat exchange surface with compact device dimensions.

Additionally, the heat exchanger is adapted for use with insulation sleeves, which minimizes heat loss in the installation. The soldering material – copper – further increases its corrosion resistance and ensures a durable connection of the plates.
