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.
Ultra-compact hydrogen precooling
- 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 printed circuit technology, an Alfa Laval HyBlocTM heat exchanger is 85% smaller than a comparable shell-and-coil or shell-and-tube heat exchanger.
This maximizes flexibility when designing the complete refuelling system and the unit is easily integrated, e.g. in the dispenser casing. As opposed to a shell-and-coil or shell-and-tube heat exchanger, there is no need to install a HyBlocTM below ground, which reduces civil work significantly.
Withstanding pressures of up to 1,250 bar, an Alfa Laval HyBlocTM allows you to design your systems for operation at 350 bar (H35), 700 bar (H70) or higher. The high-pressure capabilities of a HyBlocTM unit ensure short filling times and also makes it future proof in case new standards with higher pressures are developed.
The HyBlocTM range comprises four models, offering solutions for all capacity needs. We help you select the ideal model according to your cooling fluid, capacity requirements, etc. to maximize performance.
Safe hydrogen handling with HyBloc
Hydrogen is highly explosive when mixed with air, meaning rigorous safety measures must be taken when handling the gas. The safety of Alfa Laval’s printed circuit heat exchangers has been thoroughly proven in several demanding fuelling applications such as fuel gas supply for large ships, and land-based natural gas supply systems for industrial and domestic applications for more than 15 years.
The HyBlocTM design is based on diffusion welding of the heat transfer plates. In this process the grain structures of the plates merge, forming one solid block that can withstand very high pressure. This secures that high pressures are equally well handled on the cool and warm sides, and relief connections are therefore not required.
A revolutionary approach to hydrogen refuelling
PowerDense
Maximum sustainability under maximium pressures
Improves sustainability with the smallest metal footprint design that can still contain hydrogen pressures as high as 1250 barg!
ReFuel+
Higher back-to-back throughput for increased profitability
Low thermal mass in a highly responsive and compact solution enables greater capacity and reduced wait time between customers, extending the number of daily back-to-back refuels.
