When Trane develop their screw compressor, DB screw chillers had so much bad jobs in US. People even don't want to hear screw compressor/chiller. Then, Trane used series R / helical rotary instead of screw.
Hi could anyone help explain how i'm to charge a RTHA255 Trane Centra vac Series R Chiller? p.s. it run on R22
Do you have any literature on the equipment? Get RTHA-IOM-1A from the Trane website. You will find your answer in the manual. Why are you adding charge? Like the rest of the fellas, I'm concerned on why you are servicing equipment that you MAY not be skilled enough to work on. I think if I were you, I'd be discussing w/ the powers that be at your company,that they need to set aside some finances to send their mechanics to factory schools. An RTHA is not like a Voyager, there is a LARGE difference in compressor costs.
ouch!!! a little harsh on someone with two posts.how about a little bit of an answer so he can see its not so cut and dry. maybe he will come back .
and before all those "dont want him to kill himself" replies come flying at me.
i know, uh huh,
greasy hands if you cant find the nameplate charge and weigh it in, and you acnt figure out superheat, subcooling etc. dont do it!!! and if you are not EPA certified dont do it.
hope thats a start to make up your mind.
