Expansion noise - capillary tube into evaporator

[desA]

Hi Des,

I am changing on a weekly base blocked driers on small cup tube systems such as air driers, beverage cabinets, water coolers, domestic fridges and freezers.

This refrigerant is too good when it comes to cleaning.

By using regular 1\4 drier, the problem disappear.

Thanks very much, chemi-cool. Your experience is very valuable.

Do you perhaps have a link, or picture of the 'regular 1/4" drier' you're referring to?
