Delta T management from BelimoThe delta T manager integrated in the Belimo Energy Valve™ is a function that continuously measures the temperature spread and compares­it­with­the­system-specific­limiting­value.­If­it­falls­below­this,­ the­ Belimo­ Energy­ Valve™­ automatically­ adjusts­ the­ flow­ so­that only the amount of water actually needed to achieve the de-sired­power­ is­used.­As­a­ result,­ the­ integrated­ logic­prevents­ the­occurrence of the low delta T syndrome and ensures maximum comfort­with­ the­ lowest­ possible­ energy­ consumption.­ All­ values­can be conveniently viewed via the Belimo Cloud and can also be adjusted­at­any­time­during­operation.­For­even­better­energy­effi-ciency, delta T management can also be performed by Belimo ex-perts­through­the­Belimo­Cloud.

The buildings and buildings construction sectors combined are responsible for 36% of global final energy consumption and nearly 40% of total direct and indirect CO2

emissions.(Source: International Energy Agency, 2019, www.iea.org/topics/energyefficiency/buildings)
