H-Drive Hydraulic Booster
High-Pressure Hydraulic Booster Compressor Technology
H-Drive, the hydraulic booster from Haskel is a technological evolution in gas compression. Designed by our team of knowledgeable experts, the H-Drive hydraulic booster is configurable to a wide range of critical high-pressure applications in a variety of diverse fields and compression systems. Engineered to safely and reliably handle flows required for critical, high-pressure gas compression and transfer needs, including high-pressure hydrogen applications.
The H-Drive hydraulic booster is an innovative technology with an advanced design that stands out with its reliability and robustness, making it safe for continuous long-duration operation.
- Robust design, suitable for continuous heavy-duty applications
- Designed specifically for high-pressure gas applications, with a wide range of gasses
- Available as booster modules for seamless incorporation into OEM packages
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?
Haskel H-Drive hydraulic boosters are known for their ability to maintain gas purity with Haskel sealing technology that is effective in keeping the process gas from being contaminated. Gas purity is maintained within the levels outlined in ISO 14687 and SAE J2719 standards.
In order to achieve this our hydraulic boosters have two distinct sections, the hydraulic cylinder assembly and the gas section. The hydraulic cylinder assembly gives the drive to the piston via high pressure hydraulic oil which pushes the pistons, this in turn compresses the gas in the gas section increasing the pressure. Between the gas piston and the hydraulic cylinder assembly is a designated separation or distance piece, which isolates the gas section from the hydraulic drive, and prevents any cross contamination.
The hydraulic cylinder assembly in the middle of the booster includes three types of seals on either side of the piston rod to keep the oil inside the cylinder assembly. The primary seal, buffer seal and a wiper seal prevent any oil escaping that could lead to contamination.
The gas sections of the hydraulic booster are at either end and inside the gas cylinder is a reciprocating piston with a primary and secondary gas seal. The gas seals are designed to keep the process gas in front of the piston.
The seals on the gas piston are consumable items and over time these seals will start to wear and gas will leak past the front of the piston to the rear. Any gas that leaks around the gas seal will vent out through the seal bypass line (item A) in the distance piece. Given the pressure difference between the positive gas inlet and the atmospheric seal bypass line it prevents the process gas to mix and cross contaminate.
The distance piece also includes a number of hydraulic seals, including a rod seal which is the final barrier ensuring that any hydraulic oil is kept away from the process gas. Like the gas seals, these are consumable items and will wear over time, but if serviced correctly will not prematurely fail.
In the very unlikely event of a failure or that some oil does start to pass, the system has been designed so that any oil that leaks out of the hydraulic drive will drain out the oil bypass port in the bottom of the distance piece (item B), again the positive pressure from the gas side will prevent any oil carryover entering the gas section.
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 |
The Haskel H-Drive hydraulic booster has been designed to compress a wide range of gases safely, reliably and economically, meeting demands for high-pressure compression or other critical high-pressure gas boosting applications.
