Refrigerant inoita basa rakakosha mukuita kuti firiji yemuchina wekupisa weindasitiri itonhore. Kuisa mufiriji kunoitwa kuburikidza nekupinza nekuburitsa kupisa kwefiriji.
S&A Teyu inopa mhando dzakasiyana dzemaindasitiri ekupisa mafiriji dzinoshanda mumaindasitiri akasiyana siyana. Dzinowanzo shandiswa mafiriji ekuchengetedza nharaunda, anosanganisira R-134a、R-410a、R-407c, ayo anobatsira nharaunda zvikuru. Pamusoro pezvo, mhando dzakasiyana dzemaindasitiri ekupisa mafiriji dzinoshandisa mhando dzakasiyana dzemafiriji, saka vashandisi vanofanira kuateerera.
Mushure memakore gumi nemasere ekugadzira, tinovaka sisitimu yakasimba yemhando yepamusoro yezvigadzirwa uye tinopa sevhisi yakasimbiswa mushure mekutengesa. Tinopa mamodheru emvura anodarika makumi mapfumbamwe akajairwa uye mamodheru emvura anokwana zana nemakumi maviri ekugadzirisa. Nekukwanisa kutonhora kunobva pa0.6KW kusvika 30KW, mawater chiller edu anoshandiswa pakutonhodza manyuko akasiyana-siyana elaser, michina yekugadzira laser, michina yeCNC, zvishandiso zvekurapa, michina yerabhoritari nezvimwewo.
