Refridgerant line ice build up

[mk98064]

Walk in freezer with remote condensor on roof producing so much ice on top of box that when during defrost cycle I have heavy flow of water on floor. Line are insulated well produce so much ice. Any way to rid the icing?

what size wall is on the insulation, i assume the ice is on the suction line only from what you are saying.

Icing is result of low temperature and high moisture content.
If line insulation is inadequate, your lines will be heavily iced.

What products in what packaging are inside.
What is room temperature?

Thank you Rigbee and Nike for confering what was suspect. Very iced lines and where exposed insul is wet cutting into it. It is 1/2 in. wall, same as refer with r-22 has no problem, freezer has 404 and heavily iced and build up glacier on top of box. I was not sure if there was other optimizing issue. I am going to replace with rubatex and wrap well. Sending flowers to you both
