A condensate tank, also known as a condensate receiver, is a vessel or tank that is designed to collect and store condensate, which is the liquid formed when steam is condensed back into water.

In steam systems, condensate is produced when steam transfers its heat energy to a heat exchanger or other equipment. The condensate is then collected and sent back to the boiler to be reused as feedwater, which helps to conserve water and energy.

Condensate tanks typically include a float valve or other mechanism to control the level of condensate in the tank, as well as a vent and drain to remove air and unwanted contaminants. They are commonly made of steel, stainless steel, or other corrosion-resistant materials and are available in a range of sizes to accommodate different system requirements.

Properly designed and installed condensate tanks can help improve the efficiency and reliability of steam systems by ensuring that condensate is collected and returned to the boiler, rather than being lost to the environment. Additionally, condensate tanks can help to prevent water hammer, which can occur when steam and condensate mix in a steam line, causing damage to equipment and potentially endangering personnel.
