"MT and MTZ compressors have a large internal free volume that protects against the risk of liquid hammering when liquid refrigerant enters the compressor. MT and MTZ compressors are fully suction-gas cooled. This means that no additional compressor cooling is required and allows the compressors to be insulated with acoustic jackets, to obtain lower sound levels, without the risk of compressor overheating."

For those like me who were hurt seeing this :



Impressive work and very nice compressors you've got there! Second stage seem a bit overkill with only -75.5°C evaporating temperature don't you think? Don't you think you could also switch 2nd and 3rd stage compressor to get benefit of the 67ccm for a gas with high specific volume like R14? In every case this beauty may work like a charm

Can't wait to see this beast loaded!
