Suction temp

[Temprite]

Hello all.

Does any one have any idea of what the highest suction line temps that manufacturers rate for sealed units before they start to give trouble with overheating? (In particular Hermitique.)

Reason I ask this is because I know of a system serving a hotel that has an extra long pipe run and I noticed that the suction line is not very cool due to the length of it.Also the liquid line is strapped to the suction line also increasing the superheat.

I did once check the suction line temp and I think it was about 23 degrees c. The compressor itself is always quite hot to touch also.My belief is that eventually the excessive superheat will eventually damage the compressor.I have raised my concerns about this to another fridgy but he thinks I am worrying needlesly.Apart from this the system works perfectly.

I have thought about maybe setting up some kind of desuperheating set up on it.

Thanks all.
