High-efficiency heat exchangers
Alfa Laval high-efficiency welded heat exchangers are engineered to match the widest range of industrial processes – adding efficiency, reliability, and sustainability under extreme conditions. Determined to empower the global transition to clean energy systems, we provide energy efficient solutions with outstanding performance, compact design, and low total cost of ownership. Our global service organization ensures hassle-free and energy-efficient operation throughout your heat exchanger’s lifecycle.
Compabloc
The compact, laser welded Compabloc brings superior performance, reliability, and energy efficiency to challenging duties in chemical, petrochemical, oil, gas, and refinery applications. Easy to install, clean, and service, each customized unit does the job of up to five shell-and-tube heat exchangers.
Spiral heat exchangers
Spiral heat exchangers are the ultimate problem solvers to rely on for demanding liquid-to-liquid and two-phase duties in hydrocarbon, wastewater, mining, and other industries. With low maintenance requirements and a proven reputation for minimal fouling, they succeed where others fail.
Printed circuit heat exchangers (PCHE)
Unparalleled integrity and minimal footprint make PCHE the perfect fit for all your high-pressure duties. The unique design enables higher heat transfer rates, improved performance, and increased safety at a lower cost. Customize it to fit your specific duty – for example to preheat the feed to gas turbines to maximize overall efficiency.
HyBloc
HyBloc printed circuit heat exchangers are ideal precoolers in hydrogen refuelling stations – both H35 and H70 systems. The unique design enables back-to-back refuelling, ensuring the lowest possible customer wait times, while minimizing space requirements and installation cost.
Packinox plate-and-shell
Providing exceptional heat transfer and low pressure drop in large-scale duties, Packinox plate-and-shell is the preferred choice in several demanding high-pressure applications, such as catalytic reforming and aromatics production. Each Packinox unit is built to order and ensures exceptional heat recovery.
Packinox plate-and-frame
Suitable for large-scale processes with high flow rates and long temperature programs at limited pressure. High thermal efficiency and low CAPEX has made Packinox plate-and-frame a popular choice for carbon capture, use and storage (CCUS), long-duration energy storage (LDES), and petrochemicals production.
Olmi shell-and-tube
Alfa Laval Olmi heat exchangers are engineered for the toughest duties in chemical processing industries and refineries, for example waste heat boilers and quench gas coolers in ethylene production. Through reliable, hassle-free operation and low total cost of ownership, they help maximize plant sustainability.
