After connecting our pumping units to the devices to be treated, a leak test of the circuit is carried out. A chemical solution established according to the nature of the deposits and the metallurgy is then prepared by direct injection of the products into the water used for the hydraulic test.

The solution obtained is then put into circulation by the action of our pumps Periodic measurements of parameters such as temperature, pH, residual acidity, iron, calcium or Redox potential are carried out using laboratory equipment by SNSI technicians (example: photo-colorimeter, pH meter.,…) .

The duration of treatment depends on these analyses. Once the desired result has been obtained, the circuit is drained and the effluents are evacuated according to a process that complies with the environmental requirements to which SNSI has subscribed by obtaining its ISO 14001 certification.

DESCALING Activity oriented towards the chemical industry and steam producers. Boilers of all capacities Exchangers Refrigerants Piping Compressors Pumps… DEGREASING, PICKLING & PASSIVATION Indispensable after boilermaking work on devices whose process is incompatible with oxides. In particular: on boilers or on new works. SLUGGING Activity mainly carried out with communities and heating engineers. For each of these operations, the volume of the circuits processed can range from a few liters to several cubic meters.
