Expansion/De-aeration Tank of Thermopac

 For every 100 °C increasing temperature Hy-therm volume increases 7.5%

 Deaeration is the removal of air molecules liquid.

The simplest way of DE-aerating liquids is store liquid in tank for a certain length of time. During this time, air trapped in the liquid can rise to the surface and escape.

 Expansion tank allows  the increased volume of Hy therm.

 Expansion tank located at the highest point of the thermal system.

 Expansion tank volume should be approximately 26% - 30% of the total estimated volume.

The properly sized expansion tank should be approximately 1/4 full at start up temperatures and 3/4 full at operating temperatures. 

 The tank installed is taken care of expansion of Hy therm as well deaeration.
