What HENNLICH does

HENNLICH-HCT GmbH is a German industrial manufacturer and supplier specializing in hydraulic accumulator technology and cooling/heat exchange solutions, headquartered in St. Ingbert, Germany. Founded in 2015 as a subsidiary of the Austrian HENNLICH Cooling-Technologies GmbH, the company was established by former OLAER/Parker Olaer engineers who carry more than 150 years of combined hydraulic domain expertise. Its core product portfolio spans bladder accumulators (HBS), diaphragm accumulators (HMS), piston accumulators (HPA), pressure bottles (HDF), air/oil coolers (HCA/HCD/HCH/HCP), plate and shell-and-tube heat exchangers (HCBP/HCRWT), low-pressure pumps (HGPM), and water hammer prevention systems. The products serve industrial B2B customers across industrial manufacturing, mobile hydraulics, wind energy, water infrastructure, mining, chemical processing, and paper production, with operating pressures up to 1000 bar and full cross-reference compatibility with HYDAC, Bosch, and OLAER products.

The company generates revenue through hardware sales of standard catalogue products and custom-engineered solutions, supplemented by technical consulting and engineering services. GTM is sales-led, driven by a technical sales team providing application consultation, system sizing, and custom design support, with a complementary e-commerce storefront for standard items. All products are quoted on a per-project basis; no public pricing is available. The company is part of the larger HENNLICH Group, a fourth-generation family-owned enterprise with 850+ employees across approximately 20 countries and combined group revenue of approximately 90 million EUR as of 2021. HENNLICH-HCT holds multiple international certifications including EU Pressure Equipment Directive 2014/68/EU (Modules D, D1, H, H1), ASME VIII, DNV Marine, ATEX, EAC TR-CU, and DIN EN ISO 9001:2015, which position it as a qualified supplier for regulated industrial markets globally.

Broad incumbents

• WIKA: Global leader in pressure, temperature, and level measurement. Adjacent incumbent serving the same hydraulic and process industry customers with complementary instrumentation rather than direct accumulator competition.
• Eaton: Diversified power management and industrial components manufacturer with a significant hydraulics group. Competes in hydraulic accumulators, valves, and cooling as part of a multi-segment product portfolio serving the same European industrial OEMs.
• Parker Hannifin: Broad industrial incumbent that acquired OLAER (Parker Olaer), the very heritage from which HENNLICH-HCT's team originated. Competes across accumulators, hydraulic valves, and motion control with a far larger global footprint and OEM relationships.
• Bosch Rexroth: Large incumbent in industrial hydraulics, mobile hydraulics, and factory automation. Competes with HENNLICH-HCT in hydraulic accumulators, hoses, fittings, and cooling technology as part of a much broader motion-control portfolio.
• Continental (ContiTech): Diversified industrial rubber and fluid handling business under Continental, including industrial hoses and selected fluid power components. Competes in adjacent fluid power categories serving similar industrial OEMs.

Direct peers

• PMC Cylinders: Manufacturer of hydraulic cylinders and accumulators serving industrial and mobile applications. Directly comparable in the piston accumulator and hydraulic cylinder category with overlap in mobile hydraulics end-markets.
• HYDAC International: Global market leader in hydraulic accumulators, fluid power conditioning, and cooling technology. Most direct competitor across bladder, diaphragm, and piston accumulator lines and competing head-to-head in European industrial and mobile hydraulics accounts.
• STAUFF: German-based manufacturer of hydraulic accessories, pipe clamps, valves, and filtration. Competes in adjacent hydraulic accessory categories sold into the same industrial B2B customers with similar direct-sales-led motion.
• Roth Hydraulics: German specialist in hydraulic accumulators, cylinders, and systems with a comparable niche focus and similar European industrial customer base. Most directly comparable specialist peer by size and product overlap.

Regional players

• NOK Corporation: Japanese sealing and hydraulic component manufacturer with strength in Asia-Pacific markets. Competes in hydraulic accumulators and seals, but with primary geographic focus on Japan and Asia versus HENNLICH-HCT's European stronghold.
