Abstract
A purification apparatus for removing gases and water from a fluid in a system, including a tank which has an expansion chamber for fluid in the system. A pump pumps the fluid in a circulation circuit of which the purification apparatus is an integral part. A closed chamber has a fluid-free upper part and contains a level-sensing device which controls flow of fluid to the closed chamber. The fluid-free upper part of the closed chamber is connected with a vacuum pump which sucks gases from the closed chamber and creates a lower pressure in the closed chamber than at an outlet of the apparatus. A pressure-generating device sucks fluid from the closed chamber.
