Hybloc™ printed circuit heat exchanger

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. Its small size 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 HyBloc below ground, which reduces civil work significantly.
