THT has been researching and developing intelligentization since the late 1980s, especially in the integration and intelligence of fluid systems. On our own, THT developed respectively for central heating system, intelligent water supply system, hot air circulating system, integrated evaporating station and intelligent heat pump system, and formed the unique style and mode of THT. From the central control system to the intelligent heat exchange station has reached the leading level in China. THT is the national standard establishment unit for GB/ t29466-2012 of plate heat exchanger unit.
