De-sanding Process

Certain geographical areas face challenges due to dry climates with blowing dust and sand. The sand and dust can quickly form a layer over the entire aircraft. Similar to frost, ice and snow, sand can also contribute to the reduction of the effectiveness required by the aircraft’s lifting surfaces to fly safely.

The Multi Solution Gate RS-400S has a built-in functionality that can provide a quick flush with pure water in order to expediently remove the dust from all surfaces of the aircraft. The system will flush the aircraft with pure warm water as the plane is being pulled through the Multi Solution Gate by the electric aircraft tug. 

Under flushing ensures that the underside of the aircraft wings and body are properly de-sanded. The process is continuous and will allow the aircraft to be de-sanded before take-off or after landing in just a few minutes.

The electric aircraft tug pulls the aircraft through the wash or de-icing cycle guided by a radar-based system for exact positioning.


Today’s methods for de-icing and washing of aircraft are time-consuming and sometimes hard to predict.

With the Multi Solution Gate, a de-icing process is completed in just a few minutes regardless of weather conditions. This gives the airlines, airport authorities, and ultimately, the passengers, improved predictability in departure times.

The Multi Solution Gate offers a gentler cleaning process than traditional methods, resulting in less wear to the aircraft paint and a reduction in the need for expensive repainting downtime. A complete exterior wash of an aircraft is performed in approximately 20 minutes, depending on the aircraft model. Easier access and higher throughput allow airlines to increase their washing frequencies. Flying clean airplanes reduces overall drag, which in turn reduces fuel consumption. The aircraft also looks better!

With the Multi Solution Gate, all de-icing and washing is done in a covered facility with closed loop systems significantly reducing the possibility of discharges into the surrounding environment. The majority of all spent fluids are collected and available for a variety of recycling options.

Airlines are well aware of the fact that clean aircraft use less fuel. The speed and easy access using the Multi Solution Gate washing system will allow airlines to increase washing frequencies of their aircraft. In addition to substantial cost savings, the system helps the aviation industry with its goal of continuing to reduce its environmental footprint.

Compared to traditional de-icing methods, there is a minimal amount of equipment movement needed around the aircraft. De-icing and anti-icing processes are fully compliant with industry regulations. Final aircraft inspection takes place in a covered, well-lit environment. Our data recording system provides thorough records for de-icing and washing processes, which can be directly provided to the customer for their quality information systems.
