Standardized Aid System (SAS)

The Standardized Aid System approach (SAS) provides the same physical framework for all deployable units. Therefore, the SAS units are standardized in size and transportability. All units are stackable and utilize the same media connectors. The frame is further designed to absorb shock impulses for a controlled airdrop. Within the SAS framework, any unit can be provided fully autonomous with a combustion engine serving as the power source. The parts used are chosen purposefully for easy accessibility worldwide.


The SAS-W2500 is our unit for the purpose of water purification. The unit is the result of three years of development and testing, was presented at the international trade fair Interschutz 2022 in Hannover, and tested in a joint exercise together with THW SEEWA, B-FAST, and DEMA. The SAS-W2500 uses multi-stage filtration. A modular system enables the user to implement various filtration and desinfection processes including sediment filtration, microfiltration, ultrafiltration, active charcoal, uv-light desinfection and a chlorination module. A newly developed automated filter cleaning ensures long-standing times without manual interference. The reliability and durability of the product are emphasized by having no electrical instruments in the gasoline version.

SAS-C [In Conception]

As they also fit in the SAS frame, units of the SAS-C line will be able to provide basic broadcast and mobile communication off the grid such as short wave or FM radio and GSM.
