Hello All
I have a client that is addamant that his cold store evaporators do not require a regular cleaning (I have atated a minimum yearly with twice yearly recommended)
The evaporator coils are very dirty as enviroment is dirty and majority of product is cardboard packaged.
Stores vary between 14 and 4 DegC holding temp.
I would like some information on efficiency reduction and if possible a way of determining the reduction in efficiency of the evaporators due to build up.
What is recommended cleaning?
