Olab has been producing solenoid valves and fittings for small household appliances for several decades. Over this time research and development have aimed at solving problems felt to be most  critical by customers. Part of this research has led to the development of a series of surface treatments complying with the strictest international standards in the food sector.

 

These treatments, mentioned below, have been applied to our products:

  • TM1 (in compliance with the requirements of the American NSF/ANSI ST51 Standard (food equipment materials)
  • TM2 (in compliance with the requirements of the NSF/ANSI ST51 American Standard (food equipment materials), NSF/ANSI STD 61 (drinking water system components section 8-ph5 hot commercial 82°C), in compliance with the 1935:2004 European Regulation
  • TM3 (in compliance with the 1935:2004 European regulation, only under special conditions)

 

Our research and development in the field of surface treatments never stopped. Along with the surface treatments mentioned above (proven by several certifications obtained) a new revolutionary  treatment has been developed which inhibits the migration of heavy metals at the same time keeping the organoleptic characteristics of fluids unvaried. Almost a year of intensive research resulted in the new TM4 treatment which makes metal surfaces (brass or steel) “impermeable” because of the electrolytic deposition of a double layer of non-toxic agents, which also inhibits the emission of  noxious elements.

 

All items manufactured by OLAB, ranging from solenoid valves to fittings, may be subject to patented surface treatment to give brass surfaces self-lubricating and anti-adhesive characteristics that increase the item’s life (up to three times).
