Gas-to-liquid plate heat exchangers

From exceptionally high temperatures to media with extremely asymmetrical flow rates, Alfa Laval’s gas-to-liquid portfolio handles more than other plate heat exchangers. Built with a revolutionary asymmetric “dimple” plate design, our gas-to-liquid models provide efficient heat recovery and very low pressure drop in gas applications – all within a significantly smaller footprint than tubular technologies.


Handle more with brazed gas-to-liquid technology

  • The lightweight construction offers much greater thermal efficiency and is typically 75% smaller than comparable shell-and-tubes
  • Available as copper-brazed (GL and GLX) and 100% stainless steel (AlfaNova GL)
  • Supports gas temperatures up to 750°C with no risk of thermal fatigue. For some applications, temperatures above 1400°C are possible.
  • Very low pressure drop in asymmetric applications thanks to patented “dimple” plate design
  • Fast global delivery thanks to Alfa Laval’s advanced production and logistics capabilities as well as a stock of standard gas-to-liquid models
The unique design of our gas-to-liquid plate heat exchangers enables them to operate with much higher flow volumes on one side of the plate. They can therefore handle complicated gas media duties that are impossible for other plate heat exchangers, with very low pressure drop and the ability to resist thermal fatigue. This opens up possibilities for heat recovery in a wide range of industries, offering faster payback times as well as important environmental benefits. These advantages make our gas-to-liquid heat exchangers suitable for a number of challenging applications, such as air compression and combined heat and power.

Et brændselscellesystem bygget med Alfa Laval-pladevarmevekslere – bæredygtigt, sikkert og omkostningseffektivt

Da den tyske leverandør af vedvarende energi, HEE Technologies GmbH, designede CHP-brændselscellesystemet (kombineret varme og energi), var det et klart valg at bruge Alfa Lavals pladevarmevekslere til brændselscelle-stabelkøling og udstødningsvarmegenvinding. Systemet bruger brint som energikilde, hvilket gør det bæredygtigt, sikkert og omkostningseffektivt.
