hi, there is an course you can go on, by revco but they have been brought by thermo fisher used to costs about $3000 in the usa im not sure if they have switched it to germany now. but this is an closly guided secret, the chap there said to me if he told me then he would have to kill me. i brought an service manual from them it cost me £300 to buy, give me your email address and ill send you an refrigeration system drawing, this is an mind field the refrigerant alone is a mixture of six or seven refrigerants then once you get to an chamber temp of -100.c then you add in the argon gas then you get your -152.

kindest regards graham
