Chemical processes and technology
Chemical agents
Problem
The ingredients in chemical agents
have a strong influence on the longevity
and functionality (throughput) of the
dispensing system. The dispensing
system (hoses and pumps) should be
set up for a particular type of chemical
agent.
General types:
– alkaline to pH neutral products,
– acidic to pH neutral products
– hydrogen peroxide.
Chemical agents can damage
elastomers and plastics in the
washer-disinfector and accessories.
Hydrogen peroxide can release large
quanitities of oxygen.
