The GL series of high-efficiency plate heat exchangers are specially designed to handle high-temperature gas-to-liquid applications with very low pressure drop. Using Alfa Laval’s proven copper-brazing or stainless steel fusion bonding technologies, these ultra-compact units are gasket-free and are available in a range of sizes and plate counts for efficient, low-maintenance operation. Standard GL models support gas temperatures up to 750°C (1382°F) without risk of thermal fatigue, are provided with in-unit condensate connections, and use a patented dimple plate design to keep pressure drop low in asymmetric applications. Copper-brazed models use a lightweight brazed plate construction to offer units that are typically 75% more compact than the equivalently-rated shell-and-tube design.
