Abstract: A method for introducing additives into a closed system though a high pressure side service port is disclosed. In a first example, a method of introducing an additive into a closed system is disclosed comprising the steps of connecting a fluid flow path with the high pressure side service port of a closed system and transporting the additive from a fluid reservoir through the fluid flow path into the high pressure side service port of the system. The method may further comprise purging the closed system prior to introducing the additive into the system.
