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
amounts of oxygen.
The following chemical agents can
cause large amounts of foam to build
up:
– Cleaning agents and rinsing agents
containing tensides.
Foam can occur:
– in the program block in which the
chemical agent is dispensed,
– in the following program block if it
has been spilt,
– in the following program with rinsing
agent if it has been spilt.
