Magnesium Oxide 380V Electric Heating Cable For Heat Related Equipment

Electric Heat Trace Solution For Hotel Water And Heat Related Equipment

Electric Heat Trace Solution for Hotel Water and Heat Related Equipment is a technical heating system to secure the unstopped hot water running pipeline to be maintained at a certain temperature from the faucet end so that for a period of stop using, when the faucet is opened, there is still immediater hot water available in the pipeline.  In sanitary hot water installations, when water stops flowing it starts to cool down to air temperature. And the time to obtain hot water corresponds to the piping length between the boiler and the tap.

 

The installation of the main pipeline, boiler, heat exchanger and other heating equipment may have been done before planning for some hotels. These equipment, after a few years’ use, may cause various aging problems or local heating imbalance which will seriously affect the comfort of the hotel housing.

 

In order to meet the requirements of residents and guests for the quality of life, extend the service life of heating equipment and reduce the use cost, from the perspective of low carbon, environmental protection and easy management, electric heat tracing should be installed in the external pipeline.

 

The advantages of installing the electric heat tracing are as follows: without replacing or disassembling the original equipment, the temperature can be maintained at 50 ~ 55℃ during the water cycle.
