Ngamagama okuthutha, 'i-reefer' ibhekisela kusitsha esikhethekile esiqandisiwe noma umkhumbi wonke ohlonyiselwe ukuthwala lawo mabhokisi, eyakhelwe ukuthutha olwandle izinto ezibolayo njengemifino nezithelo, imikhiqizo yobisi kanye nenyama. Iziqukathi ze-Reefer zifakelwe izindlela zokulawula isimo sezulu ukuze kugcinwe izimo zemvelo ezisezingeni eliphezulu futhi kugcinwe ikhwalithi yempahla uma ithuthwa.
Ngaleso sikhathi, imikhumbi ye-reefer ihlukile emikhunjini evamile yokuqukatha kokubili ngokosayizi kanye nesidingo sokusebenza. Mancane uma kuqhathaniswa futhi adinga ukukhiqizwa kwamandla okukhethekile kanye nokuhlelwa kokusatshalaliswa kukagesi ukuze kunikeze usekelo oludingekayo lwesistimu yokupholisa yesiqukathi ngasinye. Ngaphandle kokukhuphuka kwezindleko zokusebenza kanye nezidingo ezijwayelekile zokunakekela, isidingo somkhakha wezokuthutha we-reefer sikhula ngokushesha.
