Pre-wetted salt spreading
More and more road administrators, countries and communities are opting for spreading pre-wetted salt. Due to its better adhesion and faster thawing effect, pre-wetted salt provides a larger degree of traffic safety. The lower consumption of salt also allows for savings. Furthermore, the lower amount of salt used and the precise spreading pattern means that less damage is caused to the environment.

Preparing the salt solution
Pre-wetted salt is suitable for almost all winter weather conditions for temperatures as low as -10°C. The brine, however, that is required for pre-wetted salt is crucial. Too weak a concentration can result in freezing, whereas too strong a concentration (saturated solution) can lead to crystallisation and to faults in the system. All of our salt solution systems work according to the "flow principle", where salt is dissolved until a saturated solution exists which is then diluted again until the concentration displays the desired properties. In doing this, the risk of crystallisation is eliminated.

Salt solution system S 3000
This salt solution system was developed as a 'plug and play' solution and was designed to allow for an expansion to include additional module components like, e.g. a fully- automatic, regulated unit or a 5000 litre storage tank. The compact S 3000 continuously produces approx. 2000 litres of unsaturated solution per hour (20- 22%). With coarse salt, 3000 litres per hour is also possible. The salt solution system has a switching function and a connector point for external sources and external filling pumps. The accumulated dirt is efficiently drained off through two sub-valves. The isolated compartment can be filled with a wheel loader. Control panels, pumps, hoses and water inlets are protected against freezing, so the operational readiness of S 3000 is guaranteed.
