For example, in the field of air conditioning and refrigeration, UHT has been building high-quality products and strictly implementing the 2g/y national standard requirements, helping customers significantly reduce customer complaints and after-sales caused by refrigerant leakage, and maintaining customers' brand image. To solve the problem of cost reduction for customers, our unique low helium test technology can reduce the helium concentration to 10%, and reduce the helium cost by more than 80% compared with Japanese competitive products. The non-standard customized equipment is highly automated, which greatly reduces the labor cost and realizes the automatic production and detection of the real black light factory.
