Dear forum member,
we just purchasing vacuum dehydration Unit (VDU), to reduce the reduce the concentration of water in our contaminated lube oil tank.
It was running very well to remove water.
and then i stop it.
when we want to start again, now the problem come.
The VDU is not removing water.
by inspecting the vacuum reading, and oil temp, We are sure that we running it above the boiling point of water (-26 inHg / 60 C)
I call vendor,
he told me that the coalescer (inside of the vacuum chamber) is dirty. I need to clean it.
Hohoho,... i just use it for a week only.
do i need to clean the coalescer always on the time of start up?
he said "yes"
Do you face the same problem with your VDU?
