I-5 gal yethu ye-PUR melter bulk yamkela i-valve yokuhamba kwakhona echanekileyo (ukubuyisela ubuntununtunu ± 1bar), exhotyiswe ngomsebenzi wokutshixa ukunqanda ukonakala kwezixhobo okanye ukhuseleko lwabasebenzi olubangelwa ziimpazamo zokusebenza. Uyilo lokucoca ulwelo kumatshini wonke lisebenzisa ukuhluza okunobunzima obuninzi. Inokuthintela iglu yePUR ekubeni iphelelwe lixesha kwaye ibangele ukuvaleka. Kule minyaka, iimveliso zenkampani ziye zamkelwa kakuhle ngabathengi.

I-gal yethu ye-55 ye-gal ye-PUR inyibilikisa isebenzisa ukufudumeza okunyibilikayo kunye nokunyibilika: Isitya sokufudumeza sibekwe ngaphezulu kweglu. Xa isitya sokufudumeza sifudunyezwa, kuphela ngumaleko ophezulu weblue yeglue onxibelelana nesitya sokufudumeza kwaye ufike kwindawo yokunyibilika kunye nokunyibilika. Inxalenye esezantsi yombhobho weglu ayinyibiliki ngeli xesha. Ukuhlangabezana nemfuno yethu yokunyibilika njengoko kufuneka kwimveliso, iglu ekumgqomo werabha inobomi bembiza ende: ubomi bembiza bunokufikelela kwiiyure ezili-16 kwi-150 ° C kunye neentsuku ezi-3 kuma-90 ° C. Kule minyaka, iimveliso zenkampani ziye zamkelwa kakuhle ngabathengi.
