Default Large 2 Stage Cascade!

planuiesc constructia unei cascade din clasa "grea" , am introdus in acest build doua compresoare de putere, fiecare cu engine 2HP si un displacement de 41,7ccm (first stage- R404a - boiling point -46,7*C) respectiv 35,7ccm ( second stage- R1150 -boiling point -104*C)

initial am dorit constructia unei cascade in 3 stagii ( 3 compresoare cu instalatie independenta) , insa gazul R14 ( boiling point -128*C)din stagia 3 m-a oprit din actiune , deoarece are un cost extrem ( aproximativ 300 euro/ kg, se vinde la cilindru de cel putin 10kg, am nevoie de ~ 5 kg) , din pacate nu am alta alternativa sau echivalent pentru gazul R14 ( care era condensat de R1150 -st2) asa ca m-am limitat din nou la o cascada in 2 stagii

insa de aceasta data am introdus compresoare de capacitati mari , lucru ce ma va ajuta sa tin in stagia 2 loaduri de ~ 450-500W la o temperatura constanta de ~ -100*C

R1150(etilena) inlocuieste R23 si R508B , iar ca echivalent il are pe R170(etan) , insa nici unul din aceste gaze nu-l poate depasi pe R1150 ca performanta , R1150 este alternativa viabila intr-o cascada cu 2 stagii!
avantajul lui R23 /R508B sunt gaze nonflamabile , dar cilindru de inalta presiune , cand vorbim de R1150 trebuie sa fim constienti ca este un gaz extrem de inflamabil comprimat in cilindru de ~ 200 atmosfere ...asa ca mare atentie !!! , nu incercati transfer in alte tipuri de cilindru sau faceti amestec de gaz , pericol de explozie , se foloseste regulator de presiune compatibil cu R1150 gaz , evident cu sensul de filet specific gazelor inflamabile , folosirea unui regulator incompatibil cu acest gaz poate duce la explozie! , de altfel feriti acest gaz de contact cu oxigen comprimat , rezultatul este dezastros!
de altfel alt warn , pentru tuburile de O2 comprimat , extrem de periculos folosit fara cap! nu se foloseste ulei sau grasimi de orice fel la manipularea , montarea regulatorului si conexiunile pe thread ! atentie mare! ask google inainte de orice actiune cu aceste tipuri de gaze!
