Through building an internationalized R&D team, MBT has overcome various technical bottlenecks and integrated the industrial top technologies and international-advanced sophisticated technologies such as the horizontally back-to-back uniaxial direct-drive centrifugal compression and full falling f­ilm evaporation. The inverter direct-drive centrifugal chiller boasts substantial benefits such as less refrigerant charge and lower noise. Also, the operation range is wider with a more compact size. Besides, COP is up to 6.399 and IPLV is up to 10.7 and all the types are under AHRI certification.
