High-Pressure Compression, Redefined.
Engineered for excellence, the H-Drive booster, began as the first hydraulic booster, now sets a new benchmark in high-pressure gas compression. Designed to handle a wide range of gases with unmatched safety, reliability, and efficiency, it’s the go-to solution for demanding applications. Backed by Haskel’s decades of expertise in high-pressure technology, the H-Drive compressor is not just a product – it’s a promise of performance.
Delivering high-pressure exactly when and where you need it. Whether working with Hydrogen, CNG, Nitrogen, Argon, Helium or other gases, from alternative vehicle fueling, to tube trailer supply and Helium blanketing, H-Drive sets the standard in reliability. This state-of-the-art product range also sets the standard in flexibility, with a modular design that allows for greater flexibility in system design and easy upgrades to custom configurations as needs progress.
How the hydraulic booster operates:
An open loop hydraulic system provides a flow of oil to one side of the H-Drive hydraulic cylinder at a time. The oil flowrate dictates the speed that the H-Drive operates which is directly proportionate to the flowrate of gas compressed.
No other hydraulic gas booster can offer you this level of quality at this value, combined with worldwide availability and a fully international support network. Watch our video that thoroughly explains Haskel’s H-Drive technology.

Why choose the H-Drive Hydraulic booster from Haskel?

Engineered to Perform
H-Drive is purpose-built to deliver consistent performance across a broad spectrum of operating pressures.
Created with serviceability and efficiency in mind, its advanced sealing system ensures extended operational life and reliable performance under continuous heavy-duty conditions.
H-Drive hydraulic boosters are the driving force behind high-pressure compression systems. Easily integrate into a complete compression system by adding an assortment of instruments, controls and piping, and connecting to an electrical control module (ECM), a process chiller, and hydraulic power unit (HPU). H-Drive hydraulic boosters are the proven choice to drive your compression system. Count on H-Drive for reliable performance, minimized product life-cycle costs, sector-leading run-lives and negligible routine maintenance requirements.
H-Drive hydraulic boosters can be integrated into systems and configured provide pressures of up to 950bar, depending on compressor configuration, and provide flowrates of up to 63kg/hr H2 - depending on compressor configuration and at higher inlet pressures of ~100bar.
Below are examples of possible HPU Integration:
Example 1 Two H-Drive hydraulic boosters, an assortment of instruments, controls and piping and an HPU fully integrated with a complete hydraulic circuit. This is suitable for system builders that want a product with the least amount of integration.
Example 2 – Two H-Drive hydraulic boosters, an assortment of instruments, controls and piping without an HPU integrated with the compressor. This allows for more flexibility regarding the positioning and installation of the HPU within the overall system.
Example 1 – Integrated HPU suitable for HPU. Zone 2 Hydrogen environments

Example 2 – Without an Integrated HPU to be supplied separately and installed outside of ATEX
