Summary

The installations are intended for processing of precious stones and metals in boiling acid.

Description

The operating principle of “Grif-ALMAZ”, “Grif-DIAMOND”, “Grif-GOLD” installations lie in vapour acids cooling and delaying them with an anti-aerosol “Grif” filter made of fibre-porous “Grifteks” fluoroplastic.
Provides fast (5-7 min) heating of crucibles to a set temperature (2-3 modes between 20 and 300 °C), automatic temperature sustention, capture of acid fog drops with an anti-aerosol “Grif” filter made of fibre-porous “Grifteks” fluoroplastic, developed by IMMS of the National Academy of Sciences, collection of condensate. Installation operation does not require auxiliary chemicals.
