Brazed aluminium heat exchangers
The Brazed aluminium heat exchanger (BAHX) technology offers a reliable and energy efficient heat transfer solution in the cryogenics industry, as they can facilitate low temperature changes. Alfa Laval provides high-performance brazed aluminium heat exchangers, maximizing thermal efficiency. Ideal for demanding applications in gas processing and liquefaction, they are widely used in olefin, liquefied natural gas (LNG), and gas processing applications.
The benefits of Brazed aluminium heat exchangers
- 2,000 m²/m³ surface area — 4 to 5 times more efficient than conventional exchangers.
- Operates at 2–3°C, reducing energy consumption.
- Reduces downtime to less than 0.01%
The low-footprint heat exchanger is perfect in the cryogenic industry, saving customers on costly downtime and maintenance costs, as well as annual emissions.
Brazed aluminium heat exchangers stands the test of time
With a century of experience in the cryogenic industry and over 16,000 units in operation, we have the expertise to fit any specifications.
- In-house simulation software based on 25+ years of R&D and tests.
- Developed for reliable performance in the most complex installations.
- Customizable designs with pressures up to 140 bar and various fin types.
How the Brazed aluminium heat exchanger technology works
The BAHX units transfer heat by passing cryogenic fluids through a compact aluminium core. The brazed construction maximizes thermal efficiency and mechanical integrity, making them ideal for demanding applications in gas processing and liquefaction.
