Alfa Laval

GL

The Alfa Laval GL product line is an ultra-compact, high-efficiency solution engineered to meet the unique challenges of simultaneously working with gas and liquid media. A revolutionary new design handles very high temperatures with very low pressure drop. Manufactured with Alfa Laval’s proven copper-brazing technology, they also ensure the reliable performance you expect from the world leader in thermal transfer.

Handle more with brazed gas-to-liquid technology

  • Our standard gas-to-liquid models support gas temperatures up to 750°C
  • For special applications, temperatures above 1400°C are possible
  • Very low pressure drop in asymmetric applications thanks to patented “dimple” plate design
  • Condensate from the gas medium drains easily thanks to condensate connection included with the unit
The Alfa Laval GL product line is the perfect choice for numerous asymmetrical heat transfer applications. They are designed with a lightweight brazed construction that offers much greater thermal efficiency and is typically 75% smaller than shell-and-tube designs used for similar duties. Furthermore, while normal copper-brazed plate heat exchangers can often only handle temperatures up to 225°C, our GL product line supports much higher temperatures with no risk of thermal fatigue. This enables superior performance in high-temperature exhaust gas duties as well as in all types of condensation applications.

How it works

Alfa Laval gas-to-liquid heat exchangers use thin, corrugated stainless steel plates to provide heat transfer from one medium to the other. Copper brazing seals the media in the plate pack, resulting in a high-efficiency heat exchanger that consists solely of surfaces that actively contribute to heat transfer. Contact points between the plates are also brazed, which improves resistance to pressure and temperature fatigue.

The arrangement of the channels formed between the plates ensures that media flow through alternate channels in a countercurrent pattern, which further optimizes the efficiency of the heat transfer. One channel is far larger than the other channel, enabling the unit to handle very large volumetric flow rates.
