Blocked Driers
I've had three in the last couple of weeks blocked enough to cause bubbles in the sightglass, funny how these things all seem to come at once. I can't remeber the last one i changed for being blocked but would be six months ago i guess.
Anyone eles had driers blocked recently, i wonder if the warmer weather plays a part.

We had a weekend years ago now when three 120w fan motors failed, took the van stock of the whole company!
I get that 'think of a customer or site then get a call' thing, must start thinking of more customers

Re: Blocked Driers
IF a drier is located between the LSV and TXV, when the unit goes into pump down, the drier freezes and defrost after all the liquid has been pumped back.
After many times the core inside breaks inti small lumps and it blocks the fine mesh strainer. I've seen it a few times.

Re: Blocked Driers
I used to only fit sporlan, but i find the danfoss ones easier to braze in. Also climate centre seems to be stocking more danfoss and less sporlan now

Re: Blocked Driers
We avoid solid core driers as they tend to break apart (and block!) the easiest. Alko (then Emerson-Alko, now just Emerson I believe) are our weapon of choice.
