Yilapho ukuqina kulwa khona nokuzinza. Izilinganiso zesistimu ye-membrane yesikhathi sokuqala zihlaba umxhwele—sikhuluma ngokukhiqiza igesi ngemizuzu embalwa. Uyayivula, ucindezele imojuli, futhi uba nokugeleza. Ilungele imisebenzi esebenzisa amashifu owodwa noma edinga igesi edingekayo.

Ngokuphambene nalokho, i-Cryogenic ASU ifana nesitimela sempahla. Sidinga isigaba eside sokuphola ukuze sifinyelele amazinga okushisa okusebenza, ngokuvamile sithatha amahora angu-12 kuya kwangu-36 ukuze sizinze futhi sikhiqize igesi yezinga elicacisiwe. Uma sesisebenza, ngokuvamile ufuna ukuyigcina isebenza.
