DEFROST de-icing salt is ideally suited to preparation for multiple reasons
It has a very high and constant NaCl percentage of 99.7 to 99.9%, which guarantees a high thawing effect with incredibly sparing use.
It does not contain any insoluble residues that can contaminate or clog up the rotary disc, spray nozzles or tanks.
The low sulphate content preserves the infrastructure, concrete and machines.
Thanks to the low ratio of insoluble residues there is no danger of clumping, thus enabling hassle-free spreading operations.
DEFROST de-icing salt is ideally suited to brine preparation
Brine settles on the entire road as a film.
Brine thaws ice and snow evenly.
Brine has a long-lasting thawing effect.
The preparation of DEFROST de-icing salt as brine offers many advantages, but in particular ecological advantages compared to other spreading options
Up to 75% less salt consumption Brine saves up to 75% salt. It reduces the costs of spreading material and application.
Lower impact on environment The enormous savings in salt drastically reduce the impact on the environment. What is more, the precise spreading of the pre-wetted salt decreases the loss of salt and drifting, with the result that grass verges, hedges etc. are protected from excessive salt use.
Targeted and comprehensive brine application Brine is applied via a spray bar. It reaches the surface of the road as a film of brine that moistens the surface completely and evenly. This means that it enables targeted and comprehensive application, dries rapidly and has a preventive effect in fighting slippery frost.
No particulate matter pollution Brine settles on the asphalt as a film and cannot be whirled back up.
No recycling costs Grits, granulate, sand etc. all have to be collected in spring and washed before they can be deposited. Just like the blow-down residues of brine production, this rinsing slurry is categorised as special waste and is expensive to dispose of.
Rapid and long-lasting thawing effect Brine starts to work immediately after application. In addition, its duration of effect on the road is significantly longer in comparison to other spreading materials: brine sticks to the road and is not wafted away by passing vehicles.
Preventive application possible If brine is applied to the dry road before snowfall, the film of brine slows down freezing and can even prevent slippery frost and the formation of ice.
