Case Story
Transfer line exchangers face some of the toughest conditions in the refinery, where hot gas, coke particles, and challenging water quality can quickly lead to erosion, fouling, corrosion, and costly failures. For operators, these issues don’t just mean maintenance headaches - they can result in serious production losses. Alfa Laval tackles these challenges head-on with two innovative types of transfer line exchangers, each engineered with unique features to maximize reliability and uptime, even under the harshest process conditions.
