The invention relates to an apparatus for the segregation of worn-out cleaning bodies consisting of resiliently deformable material such as rubber or plastic from the coolant circuit of a heat exchanger for the purpose of segregating and removing those cleaning bodies which on account of wear no longer have sufficient dimensions to clean the tubes of the heat exchanger. Cleaning bodies found still good are-together, if desired, with the new cleaning bodies replacing the rejected cleaning bodies-delivered back through the injecting device to the coolant circuit such that any air which has penetrated during the sorting or is contained in new cleaning bodies is virtually completely removed from the sponge-like cleaning bodies, and the cleaning bodies are imbibed with coolant fluid in order to assure a uniform distribution of the cleaning bodies in the coolant fluid and to prevent any floating up or sinking of the cleaning bodies and hence to prevent improper cleaning of the heat exchanger tubes. The novel apparatus permits the elimination and the replacement, as desired, of no longer effective cleaning bodies without interruption of the cooling circuit.
