Ukunakekelwa okuvamile akuqinisekisi nje kuphela ukusebenza okuvamile kweyunithi ye-water chiller kodwa futhi kunweba impilo yesevisi yeyunithi yokupholisa amanzi. Ngakho yimaphi amathiphu okunakekela avamile? Okokuqala, beka iyunithi yokupholisa amanzi endaweni enomoya omuhle; Okwesibili, shintsha amanzi ajikelezayo ngezikhathi ezithile; Okwesithathu, geza i-condenser kanye ne-gauze yothuli njalo.
Mayelana nokukhiqizwa, i- S&A I-Teyu itshale izimali zokukhiqiza ezingaphezu kwesigidi samayuan, iqinisekisa ikhwalithi yochungechunge lwezinqubo kusukela ezingxenyeni eziyinhloko (i-condenser) ye-chiller yezimboni kuya ekushiseleni kweshidi lensimbi; ngokuphathelene nempahla, S&A I-Teyu imise izindawo zokugcina izimpahla emadolobheni amakhulu aseShayina, inciphise kakhulu umonakalo ngenxa yokuhanjiswa kwezimpahla ezikude, kanye nokusebenza kahle kwezokuthutha; mayelana nesevisi yangemuva kokuthengisa, isikhathi sewaranti iminyaka emibili.
