HYDAC: the integrated fluid technology system

HYDAC is the global leader in integrated fluid technology: accumulators, filters, sensors, heat exchangers, valves, pumps, cylinders, and control electronics—all from a single manufacturer. The company is headquartered in Sulzbach (Saar), Germany, with over 9,000 employees across 50 international locations. The Italian subsidiary, HYDAC S.p.A., operates from Cassinetta di Lugagnano (Varese) with an organization divided into two business divisions, Mobile and Stationary, directly serving the Italian market.

The product portfolio is structured around four technological pillars. SB bladder-type hydraulic accumulators (up to 200 liters, 690 bar), SBO (up to 4 liters, 700 bar), and SK piston accumulators (up to 1,500 liters) have been the market standard since 1963 and comply with PED 2014/68/EU. BetaMicron filters cover pressure filtration (LF/DF/HD up to 420 bar), return (RFL/RFM), suction (SFE), and vent (BF) with ISO 16889-certified efficiencies. Sensors include EDS pressure switches, HDA transmitters, ContaminationSensor CS 1000, AquaSensor AS 1000, and EVS flow meters for Industry 4.0. The OK series air-oil heat exchangers and HEX plate heat exchangers complete the fluid technology portfolio.

HYDAC S.p.A. Italia is certified to ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and UNI EN ISO 9004:2018. It holds the internal "Free Pass" certification, which attests to its ability to deliver certified components without the need for re-testing by the customer. Multiple marine approvals (RINA, Lloyd’s, ABS, DNV-GL, Bureau Veritas, ClassNK), ATEX, IECEx, and NEC compliance for explosive zones, and ASME U-Stamp for U.S. pressure vessels.

Why choose TFS for HYDAC applications

TFS Oleodinamica, a Bosch Rexroth Certified Excellence Service Partner since 1997, operates as a service and system integration center for HYDAC components, complementing the direct operations of HYDAC S.p.A. (the Italian subsidiary responsible for commercial relations with the manufacturer).

• Custom multi-brand power units – integration of HYDAC accumulators, BetaMicron filters, OK sensors and heat exchangers with Bosch Rexroth/Casappa/Kawasaki pumps, Alfagomma valves and tubing, forming a complete, tested system.
• HYDAC ↔ Parker ↔ Bosch Rexroth cross-reference for pressure and return filters: TFS manages the replacement of Parker or Rexroth filters with corresponding HYDAC filters while maintaining the required ISO 16889 efficiency standards.
• Immediate stock on high-turnover items (BetaMicron cartridges 1300R, 0660R, 0850R; SBO accumulators 1, 2, 4 liters; EDS 3400 pressure switches) for delivery within 24–48 hours to industrial maintenance technicians throughout Italy.
• Condition monitoring programming – connection of HYDAC ContaminationSensor CS 1000, AquaSensor AS 1000 sensors, and EDS pressure switches to the line PLC for Industry 4.0 and predictive maintenance.
• On-site and in-house oil diagnostics using HYDAC FluidControl FCU instrumentation for ISO 4406 contamination analysis and validation of cleanliness levels required by the circuit’s proportional valves.
• Accumulator precharge service – verification and restoration of nitrogen precharge pressure using a dedicated cylinder and HYDAC instrumentation, performed at the TFS facility or at the customer’s site.
• National and international coverage – complementing the direct operations of the HYDAC S.p.A. branch.
