HİDROFİL ENGINEERING was founded in Ankara in 2017 by engineers with over 15 years of experience in the mechanical, hydraulic, and hydromechanical fields of the Defense Industry, with the goal of transforming fluid system designs, particularly for military vehicles, into unique products. Along the way, HİDROFİL ENGINEERING received support from TÜBİTAK's SME R&D Projects program. As part of this initiative, the HYDROSPRING variable volume hydraulic reservoir (VVR) was designed, developed, manufactured, and integrated into hydraulic systems to replace conventional atmospheric reservoirs used in hydraulic systems. HYDROSPRING has proven itself on over 30 platforms, both domestically and internationally, primarily in Defense Industry Military Engineering Vehicles, Armored Combat Vehicles, Mobile Construction Equipment, and Locomotives.

HİDROFİL ENGINEERING, with its broad engineering perspective and ability to adapt to changing project and design conditions, boasts an ambitious, innovative, experienced, and dynamic team in hydraulic, mechanical, and hydromechanical designs. In addition to designing and developing various versions of the variable displacement reservoir (VVR) HYDROSPRING, it also designs, integrates, and projects hydraulic systems, servohydraulic systems, and hydraulic power packs. Among HİDROFİL's core services are the design, manufacturing, and product verification of custom hydraulic cylinders and hydraulic accumulators tailored to specific user requirements for specific applications.

HİDROFİL, with its R&D office within METU Teknokent and a dedicated facility in Ostim for product assembly, testing, and verification, continues to grow daily with the slogan "Wherever flows operate, we are HİDROFİL."
