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 mafakitale laser chillers.
Ponena za kupanga, S&A Teyu adayika zida zopangira ma yuan opitilira miliyoni imodzi, kuwonetsetsa kuti njira zingapo zikuyenda bwino kuchokera pazigawo zapakati (condenser) za mafakitale oziziritsa kukhosi mpaka kuwotcherera kwachitsulo; pankhani ya Logistics, S&A Teyu akhazikitsa malo osungiramo katundu m'mizinda ikuluikulu ya China, atachepetsa kwambiri kuwonongeka kwa katundu chifukwa cha mtunda wautali wa katundu, komanso kupititsa patsogolo kayendedwe kabwino; pankhani ya pambuyo-malonda utumiki, nthawi chitsimikizo ndi zaka ziwiri.
