Thermal Oil Expansion Tank Design

Perform maintenance operations with the fluid at temperatures below 60 c.

Thermal oil expansion tank design. 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. It also helps in removal of moisture and non condensables during start up. Replace mechanical pump seals and gaskets only if leaks are detected. Because thermal oils expand at different rates the expansion tank capacity always should be verified against the oil properties prior to.

Expansion tank is provided in hot oil system to accommodate for the increased thermic fluid volume due to thermal expansion. This design allows for full fluid flow through the expansion tank during start ups and during times when moisture or low boilers must be vented from the system. Instead the focus is placed on specific components like pumps valves or the heater itself. 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.

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. 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. Correctly designed thermal fluid expansion tank systems are important to help provide the longest life for your thermal oil as well as the most. Because most thermal fluid heating systems are closed loop systems.

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. The design should also ensure that the temperature in the expansion tank is kept below 70 c. Design fabrication and parts thermal oil expansion tank systems are available that can include low and high boiler tanks emergency safety systems level gauges and inert nitrogen blanket kits. The properly sized expansion tank should be approximately 1 4 full at startup temperatures and 3 4 full at operating temperatures as the thermal system is brought up to operating temperature the straight leg design allows the expanded thermal fluid to enter directly into the bottom of the main expansion tank by means of a small diameter pipe.

Thermal process development can provide an expansion tank degassing tank system or help design a complete new system. Important system design principles like this often are overlooked. Do not insulate the expansion tank or the pipes connected to it.
