HyBloc
The new Alfa Laval HyBloc range of printed circuit heat exchangers (PCHE) are engineered for use as precoolers in hydrogen refuelling stations, supplying fuels to light passenger and heavy duty vehicles (HDV) such as trucks and buses. The unique design enables back-to-back refuelling, ensuring the lowest possible customer wait times, while minimizing space requirements and installation cost. HyBloc pre-coolers withstand pressures of up to 1,250 bar and are available in 4 different sizes.
What you get
- Zero waiting time between refuellings thanks to continuous refrigeration loops
- Ability to operate at very high pressures, enabling minimal filling times
- Ultra-compact, packageable design with minimal space requirements
- Well-proven, safe technology
- Leading supplier with high production capacity and application support

Compact hydrogen refuelling
Thanks to the advanced printed circuit technology, an Alfa Laval HyBloc heat exchanger is 85% smaller than a comparable shell-and-tube heat exchanger.
This highly compact design maximizes flexibility when designing the complete refuelling system and the unit is easily integrated, e.g. in the dispenser casing. Unlike a shell-and-tube heat exchanger, the HyBloc is always installed above ground, eliminating the need for underground installation and significantly reducing civil work and associated costs.
Withstanding pressures of up to 1,250 bar, an Alfa Laval HyBloc enables system designs for operations at 350 bar (H35), 700 bar (H70) or even higher. Its high-pressure capabilities ensure short filling times and make it future-ready in case new standards with higher pressures are developed.
The HyBloc range comprises four models, offering solutions for all capacity needs. Our experts help you select the ideal model according to your cooling fluid, capacity requirements, and other specifications to ensure maximum performance.
Safe hydrogen handling
Hydrogen is highly explosive when mixed with air, meaning rigorous safety measures must be taken when handling the gas. The safety of the Alfa Laval printed circuit heat exchangers has been thoroughly proven over more than 15 years in demanding fuelling applications, including fuel gas supply for large ships and land-based natural gas systems for industrial and domestic use.
The HyBloc design is based on OptiBondTM diffusion welding of the heat transfer plates. This process merges the grain structures of the plates, forming a single solid block capable of withstanding extremely high pressures. As a result, high pressures are managed equally well on both the cool and warm sides, eliminating the need for pressure relief valves.
A revolutionary approach to hydrogen refuelling
