The refrigerants wamba kupezeka kwa mafakitale laser chiller amene ozizira Brazil laser kudula makina monga R22, R134A, R410A ndi R407C. Mafiriji onse omwe atchulidwa pamwambawa ndi osamalira chilengedwe kupatula R22. Refrigerant yosagwirizana ndi chilengedwe ndi yoletsedwa ndi mayiko ambiri, chifukwa idzawononga kwambiri ozoni. Pofuna kuteteza chilengedwe, S&A Teyu imapereka R134A, R410A ndi R407C kuti makasitomala asankhe akagula S&A Teyu industrial laser chillers.
Pankhani yopanga, S&A Teyu adayika zida zopangira yuan yopitilira miliyoni imodzi, kuwonetsetsa kuti njira zingapo zimachokera kuzinthu zazikuluzikulu (condenser) za mafakitale oziziritsa kukhosi mpaka kuwotcherera kwachitsulo; ponena za mayendedwe, S&A Teyu yakhazikitsa malo osungiramo katundu m'mizinda ikuluikulu ya China, atachepetsa kwambiri kuwonongeka chifukwa cha mayendedwe akutali a katunduyo, komanso kuwongolera magwiridwe antchito; pankhani ya pambuyo-malonda utumiki, nthawi chitsimikizo ndi zaka ziwiri.
