In this embodiment, although one is used, a plurality of storage tanks 1 may be installed in parallel. Let's find out. The storage tank 100 is a material that does not cause a chemical reaction with the antifreeze is used, and is not particularly limited to a specific material.

The storage tank 100 is installed at the lower side of the front side and provided with a branch pipe 200 so as to be connectable with a plurality of test objects 2. The branch pipes 200 may be spaced apart from each other at regular intervals, and may be provided with control valves extending forward and individually controlling flow rates of the antifreeze.

The storage tank 100 includes a level indicator 102 disposed at one side of the front surface and displaying the level of the antifreeze stored therein. The level display unit 102 is installed for the operator to easily check the amount of the antifreeze currently stored in the storage tank 100 from the outside of the storage tank 100, and a tube having a predetermined diameter may be installed, but is not particularly limited. It is also possible to install electronic level gauges.

The operator can directly check the amount of the antifreeze displayed through the level display unit 102 at a time and then additionally supply it when the amount of the antifreeze currently stored in the storage tank 100 is insufficient. When the amount of the antifreeze is too large, it can be easily determined whether to take the antifreeze from the inside of the storage tank 100 to the outside. For reference, a description of the state of withdrawing the antifreeze from the storage tank 100 will be described later.

The storage tank 100 includes a gas outlet 104 installed on an upper surface, and the gas outlet 104 is generated inside the storage tank 100 while a large amount of antifreeze is stored or circulated in the storage tank 100. Is installed for the discharge of the gas. The gas outlet 104 has a lower end of the pipe having a predetermined diameter connected to the inside of the storage tank 100, and the upper end is bent roundly after extending upward. At least one gas outlet 104 may be installed and a plurality of gas outlets may be installed continuously in some cases.

The storage tank 100 further includes a lug 106 installed at the top edge. The lug 106 is installed to easily move to a desired place in a state in which the wires are wound and connected to a crane (not shown), respectively, when the storage tank 100 needs to be moved.

The storage tank 100 further includes a ladder 108 installed at one side of the above-described level indicator 102. The ladder 108 is installed by a worker to inspect the interior of the storage tank 100 or to repair and move the storage tank 100.
