All of the Multi Solution Gate models offer a brushless wash with high precision nozzles that perform high-pressure washing both over and underneath the aircraft.  While the RS-500 has both washing and de-icing capabilities, the RS-400 is designed for ordinary washing and inspection of aircraft only. The RS-400S has a built-in functionality that will de-sand an aircraft (both body and engine) quickly and safely.

This automated system is designed for all Code C/Group 3 size aircraft and smaller and is pre-programmed for each aircraft model.  The system will wash according to existing procedures for each aircraft, and special washing programs can be designed by demand and/or specifications from various airlines.  The washing time is approximately 20 minutes, depending on the aircraft model and the kind of program requested.

MSG recommends using only manufacturer approved cleaning agents for washing of aircraft.

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.
