Alfa Laval’s new gas-to-liquid plate heat exchanger portfolio revolutionises gas cooling duties.

Alfa Laval’s new portfolio of gas-to-liquid plate heat exchangers is specifically engineered to meet the needs of gas cooling duties.

The compact technology can handle exceptionally high temperatures and the challenges of simultaneously working with both gas and liquid media.

Cooling duties involving gas media are a challenge for many businesses, who have traditionally been forced to settle for bulky and inefficient shell-and-tube technology.

Alfa Laval’s new gas-to-liquid plate heat exchangers offer much greater thermal efficiency with a footprint around 75% smaller than shell-and-tubes used in the same applications.

While Alfa Laval has long had a comprehensive offering of efficient brazed plate heat exchangers, the new portfolio takes the product range a step further.

Thanks to a revolutionary “dimple” plate design in a patented asymmetric configuration, the new units are optimised to handle the distinct challenges of dealing with gas media.

This design enables very low pressure drop in applications that have disproportionate flow rates between the two media. Moreover, while standard brazed plate heat exchanger supports media temperatures up to 225°C, the gas-to-liquid portfolio can handle gas temperatures of 750°C without suffering thermal fatigue.

Due to the technology’s combination of high condensation rate with high thermal efficiency, Alfa Laval’s gas-to-liquid portfolio delivers advantages in waste heat recovery, air compressors as well as applications in charge-air coolers.

The initial launch of the gas-to-liquid portfolio features two product ranges with models in various sizes. The GLX range features a counter-current channel arrangement to optimise thermal efficiency.

It has a cross-flow arrangement and is designed with open inlets and outlets on the gas side to provide the lowest possible pressure drop.
