Can anybody help me out this topic
Many Isolator manufacturer said that the maximum relative humidity is only about 70% rh. So how if the humidity goes up to 100% inside the isolator during it’s operation.
Does the high humidity effect the test or the h2o2 for sanitisation purpose
During normal operation the humidity does not go to 100%
%RH & Temp conditioning & compressed air etc are controlling the %RH inside the isolator.
In inside the isolator the following %RH & Temp conditioning injection of Hydrogen Peroxide gas (H2O2) to build saturated vapor conditions. At dew point start to build micro condensate layer on surfaces.
I get to know about this. But unfortunally tthe situation is that. Our company isolator getting wrong right now. The humidity go up to 100 % during. Do you have experient to solve this problem. Can you suggest me what to do to solve the problem. And do you know from where i can find the regulation about isolator specification…
try some desicants
The humidity goes up during normal operation or during decontamination?
There are many factors which involve with humidity.
- Amount of H2O2 evaporation
- Starting Temperature
- Starting Humidity
- Are you having liquid inside your isolator?
- Are you cleaning the isolator?
- Are you using compressed air to control the humidity
Because having more than 100% humidity it means you will see drops or wet surfaces during normal operation. This has impact on the decontamination but also on the product which you are testing.
I work for a Isolator manufacturer but without more detailed information or actual seeing the equipment it is difficult to understand the current situation.
can you please share which recipe are you setting during VHP,In general during VHP cycle RH should be less than 20% >if it is not then first check the heater temperature of VHP system it should be more than 160>if all are okay then you need to introduce a condenser unit in air inlet
