Frequently Asked Questions (FAQ)

Breaching is the process of creating an entry point into a secured building, vehicle, or territory when traditional access is denied. While it is often associated with doors and windows, specialized breaching can involve walls or structural barriers. The goal is to allow security, military, or rescue forces to enter a designated area quickly and effectively.

Hot Entry: Relies on explosives or thermal tools to destroy a barrier. While fast, it creates significant noise, smoke, and a risk of fire or shrapnel.

Cold Entry: Utilizes mechanical and hydraulic instruments, such as the Hydronoa Door Buster or Spreaders. It is a controlled method that prioritizes safety and stealth, making it the standard for tactical operations.

Unlike explosives, Cold Entry offers total control. An operator can pause or stop the operation at any second if the situation changes. It is far safer for use in urban environments, high-occupancy buildings, or near flammable materials. Additionally, it allows for “quiet” breaching, giving tactical units the element of surprise.

While doors are the most common entry point, tactical breaching includes windows, fences, and even structural walls. Hydronoa’s versatile tools, like our specialized cutters and spreaders, are designed to handle various materials beyond just wood and metal door frames.

Our systems are engineered for filed tasks users: Special Forces, SWAT teams, Counter-Terrorism units, and First Responders (Fire & Rescue). The equipment is built to withstand the rigors of combat and emergency environments where failure is not an option.

Manual tools require significant physical effort and can be exhausting for the operator. Hydraulic tools substitute muscle power with fluid pressure, allowing a single operator to exert tons of force with minimal physical strain, for a shorter period of time keeping them fresh for the actual mission after the breach

Weight is a critical factor for Special Forces. Hydronoa systems are developed with a “lightweight-first” philosophy. Most of our tools are designed to be carried in dedicated tactical backpacks, distributing the weight evenly. This allows operators to carry the equipment over long distances or during complex climbs without hindering their mobility.

No. Through advanced engineering and the use of high-strength materials, we have achieved an industry-leading power-to-weight ratio. Even our smallest cylinders can deliver enough tons of force to breach reinforced steel doors that usually require much larger industrial machinery.

Our advantage lies in portability and speed. In places where bulky equipment cannot fit—such as narrow corridors or high-altitude entries—Hydronoa’s tools excel. Our quick-connect systems allow a team to go from “backpack to breach” in seconds.

We pride ourselves on offering “zero-maintenance” tactical gear. The systems are sealed and ruggedized. Beyond basic checks—ensuring the oil is at the correct level, checking the integrity of the hoses, and keeping the quick couplers free of debris—the equipment is built to work every time, even after long periods of storage.

Hydronoa systems are precision-engineered to work at specific pressure ratings. To ensure maximum safety and to prevent damage to the internal valves, our tools must only be operated with original Hydronoa pumps or those specifically certified by our technical department.

We offer a comprehensive one-year warranty from the date of purchase. This covers any defects in materials or workmanship. Because our gear is used in life-saving missions, we also offer technical support to ensure your kit is always mission-ready.

Yes. From freezing temperatures to desert heat, our hydraulic systems and specialized oils are tested to perform reliably in extreme environments. The rugged exterior of the tools is also resistant to corrosion and impact.

Every handle, trigger, and coupler is designed with “fine motor skill” limitations in mind. They are easy to operate even while wearing heavy tactical gloves and under the high-stress conditions of a live operation.

Safety is paramount. You must replace the hose if you see any signs of “kinking,” fraying, or leaking. Additionally, per European safety regulations, even a perfectly looking hose should be replaced every 7-10 years to prevent material fatigue-related bursts.

We recommend Tellus 15 hydraulic oil (or its direct equivalent). This specific viscosity ensures that the pump remains efficient and the seals stay lubricated without causing internal friction or clogging the valves.

The oil level should sit approximately 3-4 mm below the filler cap line. To be 100% sure in the field: extend your tool (like a Door Buster) to its maximum length. If you can still build pressure at the very end of the stroke, your oil level is sufficient.

Clean the area around the oil tank cap thoroughly to prevent dust from entering. Unscrew the cap and fill the tank until the oil reaches the 3-4 mm mark below the highest line. Do not overfill, as the system needs a small air pocket for thermal expansion.

Yes. Our door busters and spreaders are designed for both left and right-handed operators. In many models, you can simply rotate the cylinder or adjust the grip to suit the operator’s preference or the specific orientation of the door.

Yes, but this requires a specific “Underwater Configuration.” If you plan to use the tools in maritime environments, contact us to ensure your seals and pump vents are adjusted to prevent water ingress and corrosion.

Before connecting any tool to a pump, wipe both the male and female couplers with a clean, lint-free cloth. If sand or mud has entered the coupler, use compressed air to blow it out. Never force a connection if it feels “gritty.”

We offer three main types:

o   Manual: Silent and requires no power source.

o   Pneumatic: Extremely fast, powered by a standard air tank.

o   Electric/Battery: Provides consistent high-power output for prolonged operations without manual labor.
