Thermal Oil Expansion Tank

Expansion tanks are intended to be used in closed circuits of water or other fluids to allow for their expansion following a temperature increase in the heating fluid.

Thermal oil expansion tank.

Xt 8 thermal expansion tank is the 2 gal. The provisions made for thermal expansion and draining of the thermal oil are key factors to consider for the successful installation of any thermal oil heating system. The pirobloc de 2500 v hp expansion tank is a reservoir suitable for being pressurized with a diaphragm dividing the tank into two parts air and fluid. Instead the focus is placed on specific components like pumps valves or the heater itself.

Important system design principles like this often are overlooked. The expansion tank is connected to the system using a pipe known as a compensation pipe which allows us to send the increased volume produced by heating the whole circuit to the tank and in the cooling or end of day phase to compensate for the lower level produced due to an increase in the fluid s density upon cooling. When selecting an expansion tank the system volume including the initial fill of the expansion tank the operating temperature and the fluid s coefficient of thermal expansion should all be considered. Prevent permanent damage to your water heater with an expansion tank.

All water heaters regardless of whether they use heating oil natural gas or propane or even electricity can suffer the negative effects of thermal expansion as the cold water coming into the tank turns to hot heated water increasing the overall water volume via expansion and increasing pressure inside the tank. It also helps in removal of moisture and non condensables during start up. As the system pressure increases water enters the polypropylene lined water chamber of the tank expanding a diaphragm into. Expansion tank is provided in hot oil system to accommodate for the increased thermic fluid volume due to thermal expansion.

Thermal fluid expansion tanks and degassing systems are important for maintaining long oil life as well as lowering the maintenance costs on the thermal oil heater pumps and process equipment. This article will show how to do sizing of an expansion tank. Because most thermal fluid heating systems are closed loop systems. Thermal process development can provide an expansion tank degassing tank system or help design a complete new system.

System components and their function the system is made up of a pump that pushes the heat transfer fluid though an insulated piping system to a heater to the processing equipment there is an expansion tank on the system to allow for the expansion of the hot oil as it gets heated up and contraction when the hot oil is cooled down.
