Amakhoyili okushisa enziwa ngochungechunge lwamashubhu ethusi ane-aluminium noma amaphiko ethusi ukuze kwandiswe izindawo ezingaphezulu zokudlulisa ukushisa.Kuphakathi kokuthi uketshezi olushisisayo lusakazwa ngamashubhu kuyilapho umoya oshisayo udlula phezu kwamashubhu namafins.Amakhoyili okushisa amanzi ashisayo noma isitimu afakwe ohlakeni lwensimbi yeshidi.Isitimu sinikezwa futhi sikhishwe ngezihloko ezinoxhumo olunwetshwa ngohlangothi lokufinyelela lweyunithi yokubamba komoya.
