I recently built a custom bencher for someone in the US (Not from this Forum) and felt the temps were respectable and on par with what I was expecting.

Compressor was a Danfoss SC18 3/4hp LT compressor and no load was -47c and eventually -50c.

240 watts -42c
280 watts -39c
310 watts between -35c to -37c (after recover from -35c).

The gentleman I built this for is less than happpy because he was expecting -56c to -60c unloaded since he was told that even Cryoz's were doing -58c or colder.

I tried to explain that adding more refrigerant to increase load handling would result in the temps under no load being warmer than they would with a lower charge.

Anyway maybe im the one off base here so I wanted to ask you guys if these temp seemed reasonable or if maybe I was the one short changing the guy.
