Adanac's facility includes a Positive Pressure Clean Room for the assembly
and test of valves and valve related products for Oxygen Duty and other critical processes.
Adanac have both solvent and aqueous cleaning processes capable of meeting customer's specific requirements
and have process control procedures providing the level of cleanliness required by end users including Air Products, Praxair and BOC.
Procedures are continuously monitored for effectiveness as part of Adanac's ISO 9001 Quality Management
Following degreasing the cleanliness of parts is checked either by direct visual White Light and Black Light techniques or sample
wipe and solvent analysis methods.
Once the required level of component cleanliness is achieved parts move directly to the Positive Pressure Clean Room for final assembly
and pressure testing before being sealed, bagged and labelled with positive identification to prevent contamination before required
Adanac degrease and prepare valves and components for Oxygen Duty meeting the requirements of user specifications
including Air Products 4WPI-SW70003 Class AA and BOC 50000810. Also less stringent requirements including BOC 50000634 Commercial
Clean and Air Products 4WPI-SW70002 Class B.
Pressure testing facilities in the Clean Room allow cleaned/degreased valves to undergo full internal and external leak test following
final assembly without compromising cleanliness. Pneumatic test pressure up to 345barg (5000psi) can be accommodated using a variety
of gases including Nitrogen, Helium and Nitrogen/Helium mixtures.
