Iikhoyili zomphunga eziqhelekileyo, ngakumbi iModel S, zenziwe ngokudibanisa kwiziphelo ezahlukeneyo zekhoyili. Olu hlobo lwekhoyili luvumela umphunga ukuba ungene kwintloko yonikezelo kwaye ubethe kwipleyiti ukuze usasaze umphunga kuzo zonke iityhubhu. Umphunga emva koko uyancipha kubude betyhubhu uze ukhuphe i-header yokubuyisela.

I-Advanced Coil icebisa ukuba kufakwe amaqondo obushushu omoya angaphezu kwama-40°F. Siyenza le modeli ngokudibanisa kwiziphelo ezichaseneyo zekhoyili. Iikhoyili zomphunga eziqhelekileyo zisetyenziswa kwiintlobo ngeentlobo zezicelo zomoya kunye nokomisa kwimizi-mveliso eyahlukeneyo. Njengomgaqo jikelele, iikhoyili kolu luhlu zikhethwa xa amaqondo obushushu omoya angenayo engaphezulu kweqhwa kwaye umbane womphunga ugcinwa kuxinzelelo oluhlala luhleli.

Iikhoyili zohlobo lwe-S ziyafumaneka njengeekhoyili ezinzulu zomqolo omnye kunye nezimbini ezineekhoyili ezinzulu ezinomphunga kwelinye icala kunye noqhagamshelo lokubuyela kwe-condensate kwelinye icala. Sikwaqinisekisa ukuba le modeli ikwicala letyhubhu edibeneyo ye-TIG ngexesha lokwakhiwa, kwaye siyakwazi ukubonelela ngesitampu se-ASME 'U' okanye ukwakhiwa kwe-CRN.
