Ground Support & Test Equipment for Aircraft & Helicopters
At Sun Test Systems BV we specialize in the development and manufacturing of advanced Ground Support Equipment (GSE) for aircraft and helicopters. Developed in close collaboration with our customers, each system is engineered for reliable performance, even in the most demanding environments. Our hydraulic carts not only supply hydraulic power, but also clean and regenerate hydraulic oil, enhancing operational safety and reducing maintenance downtime.
To further streamline maintenance processes, we integrate multiple support functions into one compact, high-performance unit. These multifunctional systems combine hydraulics, electrical power, pneumatics, air conditioning, nitrogen supply, and lighting, offering a space-saving solution that’s available in both modular and non-modular configurations. In addition to our hydraulic and multi functional carts, we offer auxiliary equipment such as dye mix trolleys and aircraft washing systems to meet a wide range of maintenance and testing needs.
