RT: Refrigeration data. Refrigeration is my bread & butter. I repair, maintain, install and troubleshoot systems.
With the @helium and @DraginoTech platforms and sensors onboard, conditions can be seen from afar.
Major projects forthcoming, watch this space. https://t.co/Bhq35DQifM
RT：制冷数据。制冷是我的面包；黄油我维修、维护、安装和排除系统故障。
有了“氦”和“DraginoTech”平台以及船上的传感器，可以从远处看到情况。
重大项目即将到来，请观看此空间。https://t.co/Bhq35DQifM
